Product Details

BD204 PNP Power Transistor - 8A / 60W for Audio & Motor Drive

The BD204 is a PNP power transistor housed in a TO-220 package, built to handle up to 8A of collector current and 60W of power dissipation. It's a classic choice for the PNP half of push-pull output stages in audio amplifiers, as well as DC motor control and relay/solenoid driving in hobbyist and repair projects.

Functions & Applications

High Current Capacity: Handles up to 8A of continuous collector current for demanding loads.
60W Power Dissipation: Suited for output stages that need to sink real power (with adequate heatsinking).
TO-220 Package: Easy to mount on a heatsink using a standard bolt-on or clip fixing.
PNP Complement: Pairs with an NPN counterpart to build symmetrical push-pull amplifier or driver stages.
General-Purpose Power Switching: Works well for motor, relay, solenoid and heater control circuits.

Frequently Asked Questions

Q: Does the BD204 need a heatsink?
A: For most of its rated 8A/60W capability, yes - a suitable heatsink bolted to the TO-220 tab is needed to keep junction temperature safe under sustained load.

Q: What is the complementary NPN transistor for the BD204?
A: The BD204 is commonly paired with the BD203, its NPN complement, forming a matched pair for push-pull output stages.

Notes

For sustained operation near the 8A/60W rating, proper heatsinking is essential to avoid thermal shutdown or damage.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
