Description
Product Details

BD201 Power Transistor - 8A NPN for Audio & Motor Control

The BD201 is an NPN power transistor in a TO-220 package, rated for 45V and 8A, commonly used in audio power stages, DC motor drivers and general high-current switching circuits. Its TO-220 case allows it to be mounted directly on a heatsink for sustained power dissipation.

Functions & Applications

High Current Capacity: Handles up to 8A, suitable for motor drivers and power output stages.
TO-220 Package: Easy to mount on a heatsink for continuous high-power operation.
60W Power Dissipation: Enough headroom for demanding audio and switching applications.
Robust 45V Rating: Comfortable margin for 24V/36V power supply designs.

Frequently Asked Questions

Q: Does the BD201 need a heatsink?
A: For any load approaching its 60W dissipation rating, yes - a heatsink is strongly recommended to keep the junction temperature safe during sustained operation.

Q: What is the complementary PNP part for BD201?
A: The commonly paired complementary PNP transistor is the BD202.

Notes

Recommended to mount on a heatsink for applications near maximum power dissipation.
