Transistor BC328 PNP 25V / 0.8A

Product information:

The BC328 transistor is a versatile PNP-type transistor known for its reliability and performance in various electronic applications. With a maximum current of 800 mA and a maximum voltage of 25 V, this transistor offers solid performance for a wide range of projects.

Thanks to its low collector-emitter voltage (VCE) and high current gain factor (hFE), the BC328 is ideal for use in switching circuits, signal amplifiers and power amplifiers. The compact TO-92 package makes it easy to integrate this transistor into various electronic designs.

What Does a PNP Transistor Do?

A PNP transistor is a type of bipolar transistor that operates by applying a small current or voltage between the base and the emitter to control a much larger current between the emitter and the collector. The key feature of a PNP transistor is that current flows from the emitter to the collector (unlike an NPN transistor, where current flows from the collector to the emitter).

What a PNP transistor does:

Switching: If the base of the PNP transistor is lower than the emitter (more negative), the transistor turns 'on,' allowing current to flow from the emitter to the collector. This is used to switch current circuits.

Amplifying: Similar to an NPN transistor, a PNP transistor can use a small input current (base current) to control a larger current through the collector. This makes it a useful amplifier for signals.

The base current of a PNP transistor must be negative relative to the emitter to turn the transistor on, meaning the circuit and polarity diagram are often reversed compared to an NPN transistor.

In summary: A PNP transistor allows current to flow from the emitter to the collector if the base has a lower voltage than the emitter.
