Frequently Asked Questions

Q: Is a heatsink required for the BD829?
A: Yes, for continuous operation with high loads (typical in audio amplifiers), a heatsink with thermal paste is mandatory. Without proper thermal management, the junction temperature will exceed safe limits.

Q: What is the complementary PNP part for BD829?
A: The complementary PNP transistor is the BD830. Together they form a matched pair for symmetrical push-pull amplifier stages.

Notes

Requires heatsink and thermal paste for safe operation above moderate current levels. Not suitable for breadboarding; through-hole soldering to PCB recommended.

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