Product Details

BD176 PNP Power Transistor - 3A, 30W in Compact TO-126

The BD176 is a PNP power transistor housed in a TO-126 package, designed to handle up to 3A of collector current and 30W of power dissipation. It is commonly used as the PNP complement in push-pull power stages, motor control circuits and audio amplifier output stages.

Functions & Applications

3A Collector Current: Handles moderate-power switching and amplification tasks with headroom.
30W Power Dissipation: Suitable for continuous operation in audio and motor driver stages with adequate heatsinking.
TO-126 Package: Compact power package with a metal tab for easy heatsink mounting.
Complementary Pairing: Pairs with the NPN BD175 for symmetrical push-pull output stages.

Frequently Asked Questions

Q: What is the complementary NPN transistor for the BD176?
A: The complementary NPN part is the BD175, commonly used together in push-pull power stages.

Q: Does the BD176 need a heatsink?
A: For loads approaching its 30W power dissipation rating, a heatsink attached to the TO-126 metal tab is strongly recommended to keep junction temperature safe.
