Product Details

BDW84D Power Darlington - Industrial Switching & Audio Amplifier Output Stage

The BDW84D is a PNP Darlington configuration power transistor designed for high-current switching and linear amplification in demanding industrial and audio applications. With a maximum collector current of 15A and Vceo rating of 120V, it delivers the base drive efficiency and voltage robustness required for robust power supply control and complementary output stage pairs in amplifiers.

Functions & Applications

High Collector Current: Handles up to 15A, ideal for driving loads directly without intermediate stages.
Darlington Configuration: Extreme current gain translates to minimal base drive current, simplifying gate logic.
Robust Voltage Rating: Vceo of 120V ensures safe operation in high-rail power supplies and audio amplifiers.
TO-247 Package: Large copper pad for excellent heat dissipation; easy to mount on heatsinks.
Complementary Pair: Works seamlessly with NPN BDW83D for push-pull and output stage designs.

Frequently Asked Questions

Q: What is the complementary NPN Darlington for the BDW84D?
A: The complementary NPN part is the BDW83D. Both share identical voltage and current ratings, making them ideal for complementary push-pull output stages in audio amplifiers.

Q: Does the BDW84D require a heatsink?
A: For continuous operation at high currents (above 5A), a heatsink is strongly recommended. The TO-247 package includes a mounting flange designed for standard heatsinks to keep junction temperature within safe limits.

Notes

Power transistor—requires heatsink for continuous operation above 5A. Ensure adequate thermal contact between device and heatsink using thermal paste. Verify base-drive circuit can supply sufficient base current for intended load.

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