BD140 PNP Transistor: Pinout, Equivalents & Applications

BD140 DescriptionThe BD140 is a silicon-based medium power PNP transistor widely used in audio amplifiers, power drivers, and quasi-complementary or complementary circuit designs. Packaged in a compact TO-126 form factor, it is capable of handling collector currents up to 1.5A, making it suitable for driving relays, motors, speakers, power LEDs, and other medium-power loads. With collector-emitter and collector-base voltage ratings up to 80V, the BD140 delivers stable and reliable performance in both analog and power management applications.The transistor features a low saturation voltage of approximately -0.5V and a power dissipation capability of around 12.5W, which enhances its efficiency in amplifier and switching circuits. Its DC current gain (Beta) ranges from 40 to 160, providing flexible amplification characteristics for different circuit requirements. In many audio and embedded applications, the BD140 is commonly paired with the BD139 NPN transistor to form complementary output stages, enabling smooth handling of positive and negative signal cycles.(Contact us for a quote) BD140 Operation PrincipleThe operation of the BD140 PNP transistor mainly relies on the current control relationship between the base, emitter, and collector. When the emitter maintains a higher potential than the base, the transistor enters the conduction state, allowing current to flow from the emitter to the collector. However, when a positive voltage is applied to the base so that the base-emitter junction no longer satisfies the conduction condition, the current flow between the collector and emitter stops, causing the transistor to enter the cut-off state.In conduction mode, the BD140 can drive currents of up to approximately 1.5A through the emitter-collector path, making it suitable for controlling medium-power loads such as relays, motors, LEDs, and audio power stages. When operating near saturation, the transistor provides a relatively low voltage drop, helping improve circuit efficiency. Once the base current is removed, the BD140 switches into cut-off mode and blocks further current flow. BD140 Key SpecificationsParameterValuePart NumberBD140DescriptionTRANS PNP 80V   1.5A SOT-32Lead Free   Status / RoHS StatusLead free /   RoHS CompliantVce Saturation   (Max) @ Ib, Ic500mV @ 50mA,   500mADC Current   Gain (hFE) (Min) @ Ic, Vce40 @ 150mA,   2VMounting   TypeThrough HoleMoisture   Sensitivity Level (MSL)1 (Unlimited)Current -   Collector (Ic) (Max)1.5ACurrent -   Collector Cutoff (Max)100nA (ICBO)Voltage -   Collector Emitter Breakdown (Max)80VPower - Max1.25WOperating   Temperature150°C (TJ)Transistor   TypePNPPackageTO-126Base Product NumberBD140(Contact us for a quote) BD140 Pinout1.

Audio Power Amplifier CircuitOne of the most common applications of the BD140 is serving as a driver-stage or output-stage transistor in audio power amplifiers. In practical circuits, the BD140 is often paired with NPN transistors such as the BD139 to form a complementary push-pull output configuration, handling both the positive and negative half-cycles of audio signals. 2. Motor and Relay Drive CircuitWith a maximum collector current of approximately 1.5 A, the BD140 is suitable for driving low and medium-power loads. In embedded control systems, it acts as a current amplification and switching device, using a small base current to control a larger load current to realize functions such as motor start-stop and relay switching. 3. Voltage Regulation and Power Management SystemThe BD140 is also widely used in linear regulators, power regulation and voltage control circuits. In analog power supply designs, it can function as a series pass transistor. By adjusting base bias, it controls output voltage and current to achieve voltage stabilization. 4. Switching Control and Logic Drive CircuitIn digital and analog circuits, the BD140 is commonly used as an electronic switch for LED control, power switching, and buzzer driving. It supports logic-level control and is compatible with embedded systems such as MCUs and DSPs. 5. Teaching Experiments and Basic Electronic DesignFeaturing a simple structure, low cost and versatile applicability, the BD140 is a widely used component in electronic teaching and experimental projects. It is adopted as a demonstration device in basic transistor experiments, motor control tests, and analog amplification experiments. BD140 EquivalentsCommon equivalents of BD140 include TIP42C, 2N2907, BC327, BC557, SS8550, and S8550. These devices are all PNP transistors and can, under certain conditions, be used as functional substitutes for BD140 in medium- and small-power switching, current amplification, and audio driving applications. Sound-Controlled DC Motor Circuit with CA3140 and BD140This circuit diagram illustrates a classic sound-controlled DC motor driver using the CA3140 operational amplifier as a voltage comparator. The front-end stage uses an electret microphone (MIC) to capture sound vibrations and convert them into weak electrical signals. This signal is fed into the inverting input of the CA3140, while the non-inverting input is connected to a voltage divider formed by a 10K potentiometer.By adjusting the potentiometer, a trigger threshold (sensitivity level) can be set. When the voltage generated by the sound signal exceeds this preset value, the output of the op-amp (Pin 6) switches state, triggering the subsequent driver stage.The output stage adopts a multi-level current amplification structure to drive a DC motor with higher power requirements. Since the CA3140 has limited output driving capability, 2N3906 and BD140 transistors are introduced in the circuit.When the CA3140 produces a valid output signal, it first switches the 2N3906 transistor, which then drives the high-power BD140 PNP transistor into conduction, allowing current to flow through the DC motor. This design effectively replaces a physical switch with a sound-based control signal.(Contact us for a quote) BD139 vs BD140 The BD139 and BD140 are among the most famous "complementary pairs" in the world of electronics.
