Product Details

BD136 PNP Power Transistor - Reliable Switching & Amplification

The BD136 is a PNP power transistor housed in a TO-126 package, designed for 1.5A collector current and up to 45V, making it suitable for driving motors, relays and audio output stages. It is often paired with its NPN complement to build push-pull amplifier stages in hobbyist and repair electronics.

Functions & Applications

1.5A Collector Current: Handles moderate power loads like small motors and relay coils.
TO-126 Power Package: Tab-mounted design allows attachment of a heatsink for improved thermal performance.
45V Rated: Suitable for typical 12V-24V automotive and hobbyist power circuits with headroom.
Complementary Pair Available: Pairs with the NPN BD135 for symmetrical push-pull output stages.

Frequently Asked Questions

Q: What is the complementary NPN part for the BD136?
A: The complementary NPN transistor is the BD135, commonly used together in push-pull amplifier output stages.

Q: Does the BD136 need a heatsink?
A: For currents approaching 1.5A or continuous operation near its 12W power dissipation limit, attaching a heatsink to the TO-126 tab is recommended to avoid thermal shutdown.
