What are the key features of BD536?

  • PNP power BJT with 60 V VCEO and 8 A collector current capacity for medium-power switching and linear amplification
  • Minimum DC current gain (hFE) of 15 at high collector currents ensures reliable base drive from standard logic or MCU outputs
  • TO-220AB package with bolt-down tab allows direct heatsink mounting for continuous 8 A operation without thermal runaway

What is BD536 used for?

The BD536 is used in audio power amplifier output stages, DC motor speed controllers, and linear power supply pass elements where a PNP transistor handling up to 8 A at 60 V is required. Its TO-220AB package bolts directly to chassis heatsinks, making it practical in off-road vehicle lighting controllers and industrial relay driver circuits. Complementary pairing with the BD535 NPN device enables push-pull Class AB audio output stages with symmetrical drive characteristics.

Frequently Asked Questions

What are the maximum collector-emitter voltage and continuous collector current ratings for the BD536?

The BD536 is rated for a maximum collector-emitter voltage (VCEO) of 60 V and a continuous collector current (IC) of 8 A. These ratings make it suitable for medium-power PNP applications such as 24 V or 48 V motor drive circuits where the transistor must handle sustained load currents without exceeding its safe operating area.

How does the BD536 perform in a complementary push-pull audio amplifier paired with a suitable NPN transistor?

In a complementary push-pull output stage, the BD536 PNP and a complementary NPN such as BD535 handle the negative and positive half-cycles respectively, each rated at 60 V and 8 A to deliver power into 4-ohm or 8-ohm speaker loads at supply rails of plus-or-minus 30 V. The minimum hFE of 15 keeps base drive current below 540 mA even at full 8 A collector current, which a driver transistor can supply without saturation.

What heatsink is needed to operate BD536 continuously at 8 A collector current in a 25 degree C ambient environment?

The BD536 in TO-220AB has a junction-to-case thermal resistance of approximately 3.1 degrees C per W. At 8 A with a VCE(sat) near 0.5 V, power dissipation reaches about 4 W, requiring a heatsink with thermal resistance below 15 degrees C per W to keep the junction below 150 degrees C. A small 40 mm x 40 mm aluminum heatsink with thermal compound is typically sufficient for continuous 8 A operation.
