BD136

Overview

The BD136 is a PNP silicon epitaxial planar transistor designed for audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. It features high DC current gain, with a minimum hFE of 25 at Ic=1.5A, Vce=-4V. Key electrical ratings include a collector-emitter voltage (VCEO) of 45V, collector-base voltage (VCBO) of 45V, and emitter-base voltage (VEBO) of 5V. The device supports a continuous collector current (Ic) of 1.5A and base current (IB) of 0.5A. Total power dissipation is rated at 1.25W at Ta=25°C and 12.5W at Tc=25°C, with a derating factor of 10mW/°C above 25°C. Operating and storage junction temperatures range from -55°C to +150°C.

Feature Summary

Designed for audio amplifiers and drivers in complementary or quasi-complementary circuits
High DC current gain for effective signal amplification
Lead-free and halogen/BFR-free design compliant with RoHS standards

Applications

Audio amplifier circuits
Driver stages in complementary configurations
Quasi-complementary circuit designs

Procurement Notes

Verify the specific package variant, as BD136 devices are available in TO-225AA (TO-126) and SOT-32 packages. Confirm RoHS compliance status and lead-free designation for environmental requirements. Check for obsolescence notices, as some variants like BD13616S have been marked as discontinued by distributors. Ensure the selected part matches the required thermal dissipation capabilities for the intended application.

Selection Notes

Select the BD136 when a PNP transistor with 45V VCEO and 1.5A Ic is required for audio applications. It serves as the complementary pair to NPN types such as BD135 and BD139. Consider the thermal management needs, as power dissipation varies significantly between ambient and case temperature mounting. Verify that the required DC current gain meets the minimum specifications for the circuit design.

Part Context

The BD136 belongs to a family of medium-power silicon PNP transistors manufactured by onsemi. It is part of a complementary set that includes NPN counterparts like the BD135 and BD139. These transistors are engineered for use in audio output stages where matched performance in complementary topologies is essential. The series offers robust reliability for consumer and industrial audio equipment.
