Product Description

BC327 BC32725 PNP Transistor (45V, 0.5A0.8A)

General Purpose PNP Switching and Amplification Transistor

The BC32725 is a widely used generalpurpose PNP silicon transistor in a TO92 package. It serves as the complementary PNP counterpart to the NPN BC33725 transistor and is ideal for switching, amplification, and audio driver stages.

High Current Gain Minimum hFE of 160 (within the 160400 range) for strong amplification.
PNP Complement Pairs with BC33725 NPN for push-pull circuits and audio amplifiers.
CollectorEmitter Voltage: 45V (max).
Collector Current: 500mA to 800mA (varies by manufacturer).
The "-25" suffix indicates the hFE rank, representing a gain range of 160 to 400 at 100mA.
Verify pinout: For the TO-92 package, the pin configuration is usually Collector, Base, Emitter.

Troubleshooting

Transistor not switching:

  • Verify baseemitter voltage is below 0.7V (PNP turn-on) to turn on.
  • Check base current and resistor values.
  • Ensure load current does not exceed maximum rating.

Excessive heat:

  • Verify collector current within limit.
  • Ensure power dissipation does not exceed 625mW.
