BD140

Overview

The BD140 is a plastic medium-power silicon PNP transistor designed for audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. It features a collector-emitter voltage (VCEO) of 80 V, a collector current (Ic) of 1.5 A, and a total power dissipation (PD) of 1.25 W at 25°C case temperature. The device offers a minimum DC current gain (hFE) of 40 at Ic = 0.15 A. Operating junction and storage temperatures range from -55°C to +150°C.

Feature Summary

Designed for use in audio amplifiers and drivers with complementary or quasi-complementary circuit topologies
Provides high DC current gain for effective signal amplification
Constructed with lead-free and halogen/BFR-free materials compliant with RoHS standards

Applications

Audio amplifier stages
Driver circuits
Complementary output configurations
Quasi-complementary output stages

Procurement Notes

Verify the specific manufacturer source, as BD140 components are produced by multiple vendors including onsemi and STMicroelectronics. Confirm that the received part matches the required pinout and electrical specifications for your design. Ensure compliance with environmental directives such as RoHS if applicable to your project requirements.

Selection Notes

Select this component when a medium-power PNP transistor is required for audio applications. It serves as the complementary pair to NPN transistors like the BD135, BD137, and BD139. Consider the 80 V collector-emitter voltage and 1.5 A continuous current rating to ensure adequate headroom for the intended load and supply voltages.

Part Context

The BD140 belongs to a series of plastic medium-power silicon PNP transistors. It is electrically complementary to the BD135, BD137, and BD139 NPN transistors. This pairing allows designers to create balanced push-pull output stages for audio equipment and other driver applications requiring matched performance characteristics.
