Why the HYG009N04LS1C2 Excels in UAV Applications

High Current Handling for Power-Intensive Operations

The HYG009N04LS1C2 supports a continuous drain current of 200 A at Tc=25°C (141 A at Tc=100°C) and a pulsed drain current of up to 800 A, making it ideal for UAVs with high-power demands, such as FPV racing drones and industrial drones. For instance, FPV racing drones may require motor currents of 40–150 A per motor during bursts, while industrial drones can exceed 100 A for heavy-lift tasks. The 800 A pulsed current rating allows the MOSFET to handle short-duration surge currents during rapid throttle changes or takeoff, provided these pulses are brief and adequately managed with proper thermal design. This supports reliable power delivery for motors and other high-current components in demanding UAV operations, but engineers should ensure pulse conditions fall within safe operating limits.

Ultra-Low On-Resistance for Enhanced Efficiency

With an on-resistance of 0.75 mΩ at VGS=10V (1.05 mΩ at VGS=4.5V),the HYG009N04LS1C2 significantly reduces conduction losses. At 200 A continuous current, this translates to approximately 30 W of power dissipation—manageable with adequate heat sinking or active cooling. However, in compact UAVs with limited space and airflow, this thermal load must be carefully managed to maintain safe operating temperatures and ensure long-term reliability. Low RDS(on) is especially critical in battery-powered drones, where every watt saved contributes to longer flight times. In comparison, a typical MOSFET with a 10 mΩ on-resistance would dissipate around 400 W at the same current level, making HYG009N04LS1C2 a far more efficient choice. Its reduced heat generation allows for smaller thermal solutions and more compact power system designs, improving both endurance and performance in consumer and industrial UAVs.

Suitable Voltage Rating for Common UAV Batteries

The 40 V drain-source voltage rating supports UAVs using 3S to 8S LiPo batteries (11.1 V to 33.6 V fully charged), covering most consumer drones (e.g., DJI Phantom 4 series, 4S at 15.2 V nominal) and many industrial drones (6S to 8S). For 6S batteries (25.2 V fully charged), the 14.8 V voltage margin provides robust headroom to tolerate switching-induced transients. For 8S batteries (33.6 V), however, the remaining 6.4 V margin is quite narrow, and successful use depends on effective transient suppression, clamping, and conservative design practices to prevent voltage overshoot from exceeding the 40 V maximum rating. For 10S (42 V) or 12S (50.4 V) systems, the 40 V rating is insufficient, as industry standards recommend a 20–30% voltage margin (e.g., 60 V MOSFET for 50.4 V), therefore, this MOSFET is not suitable for main power stages in 10S (42 V) or 12S (50.4 V) UAV systems, as these exceed the 40 V maximum drain-source voltage rating. But it may still be appropriate for auxiliary circuits or subsystems within such platforms, as long as those specific circuits operate at voltages safely below 40 V.

Robust Reliability for Demanding Environments

The HYG009N04LS1C2 is 100% avalanche tested with a 780 mJ single-pulse avalanche energy rating (L=0.3 mH), enabling it to withstand voltage spikes from inductive loads like motors, which are common in UAVs during switching events. Its wide junction temperature range of -55°C to +175°C, combined with low thermal resistance (2°C/W junction-to-case, 45°C/W junction-to-ambient), supports reliable operation in extreme conditions, such as high-altitude flights (-40°C) or hot climates (+85°C ambient). This robustness ensures durability in industrial drones and outdoor applications, reducing the risk of failure under thermal stress or electrical transients.

Fast Switching for Precise Motor Control

With switching times of 15 ns (turn-on delay), 98 ns (rise time), 215 ns (turn-off delay), and 99 ns (fall time), along with a total gate charge of 89 nC at VGS=10V and a gate resistance of 1.9 Ω, the MOSFET supports efficient high-frequency PWM switching—commonly in the 8 kHz to 48 kHz range—making it well-suited for electronic speed controllers (ESCs) in UAVs. These characteristics ensure precise motor control and minimize switching losses, supporting responsive throttle adjustments in FPV racing drones and precise control in industrial drones. The moderate gate charge and gate resistance simplify gate driver design, reducing complexity and cost in ESC circuits, enhancing overall UAV performance.

Compact and Lightweight Package

The PDFN5*6-8L package (5x6 mm) is compact and lightweight, reducing PCB footprint and drone weight, which is critical for maximizing flight endurance and payload capacity in UAVs. The small package also minimizes board-level inductance, improving energy transfer efficiency in high-current applications like ESCs and DC/DC converters. This design enables space-efficient integration into UAV electronics, making the MOSFET suitable for both compact consumer drones and larger industrial platforms where weight and space constraints are key considerations.

Environmental Compliance

The HYG009N04LS1C2 is RoHS compliant and halogen-free, aligning with environmental regulations in markets like the EU, Korea,etc. This compliance is essential for commercial UAVs, ensuring they meet global standards for environmental safety. By using eco-friendly materials, the MOSFET facilitates regulatory approval, making it a practical choice for manufacturers targeting commercial and industrial drone markets.

Versatile Applications in UAV Systems

The MOSFET’s specifications make it suitable for use in multiple UAV subsystems, such as ESCs, DC/DC converters, and battery protection circuits. In ESCs, its high current handling and low Rds(on) ensure efficient motor control. In DC/DC converters, its fast switching and high efficiency support voltage regulation for subsystems like sensors and cameras. In battery protection circuits, it manages high currents with minimal voltage drop, protecting against overcurrent conditions. This versatility allows manufacturers to use the same MOSFET model across different subsystems, simplifying design and inventory management.

Versatility Across UAV Types

The HYG009N04LS1C2’s specifications make it suitable for a range of UAV categories, each with distinct power and performance requirements:

Consumer Drones

For aerial photography and recreational drones using 3S to 4S batteries (11.1 V to 14.8 V nominal, 12.6 V to 16.8 V fully charged), the 40 V rating provides ample headroom for 4S batteries (nominal 14.8 V, fully charged up to 16.8 V), ensuring safe operation even under transient conditions such as motor switching or brief voltage overshoots, and the 200 A current capacity supports motor currents of 10–40 A per motor in quadcopters or hexacopters (e.g., DJI Phantom 4 series, 4S at 15.2 V nominal). Its efficiency and reliability ensure stable performance and extended flight times.

FPV Racing Drones

Using 4S to 6S batteries (14.8 V to 22.2 V nominal, 16.8 V to 25.2 V fully charged), the MOSFET’s 800 A pulsed current rating handles bursts up to 150 A per motor, and its fast switching (98 ns rise time) supports rapid throttle response for agile maneuvers. The 40 V rating is sufficient for 6S (25.2 V) with a 14.8 V margin, making it ideal for competitive racing.

Industrial Drones

For surveying, agriculture, or light payload delivery with 6S to 8S batteries (22.2 V to 29.6 V nominal, 25.2 V to 33.6 V fully charged), the 200 A continuous and 800 A pulsed current ratings support high-power motors (100+ A in heavy-lift scenarios). The 40 V rating is adequate for 8S (33.6 V) with a 6.4 V margin, though careful transient management is needed. Its thermal performance and avalanche rating ensure reliability in harsh environments.

VTOL and Hybrid Fixed-Wing UAVs

For drones with up to 8S batteries, the 780 mJ avalanche energy rating handles voltage spikes during flight mode transitions, and the high current capacity supports motor demands. The 40 V rating aligns with 6S to 8S systems—though for 8S, it offers limited headroom and requires good PCB layout and transient protection—ensuring reliability in complex operations.

Battery-Powered Fixed-Wing UAVs

The MOSFET’s low Rds(on) minimizes conduction losses, improving power efficiency and reducing heat generation—critical for long-endurance missions. Its compact package lowers overall system weight, supporting fixed-wing UAVs with up to 8S batteries and extending mission duration through improved energy-to-weight performance.
