BC327 PNP Transistor Pinout Datasheet

Introduction

The BC327 transistor is a PNP bipolar junction transistor (BJT) designed for low to medium power switching and amplification. With its ability to handle a collector current up to -800mA, it is suitable for driving loads such as relays, LEDs, and small motors, making it a preferred choice for a variety of switching applications. Its moderate power handling capacity, along with good frequency response, allows it to be employed in both analog and digital circuits.

Encased in the TO-92 plastic package, the BC327 transistor provides excellent reliability at a low cost. It features a maximum collector-emitter voltage (Vce) of -45V, making it suitable for circuits with relatively higher voltage requirements compared to general small-signal transistors. The BC327 also comes in gain groupings (A, B, C), providing flexibility in selecting the right variant with DC gain (hFE) between 100 and 630.

BC327 PNP Transistor

The transistor is highly popular in audio amplifier stages, switching regulators, signal processing units, and microcontroller interface circuits. It offers stable performance, low saturation voltage, and the ability to deliver moderate current, which makes it useful in both educational projects and professional designs. Because of its versatility and robust design, the BC327 remains one of the go-to PNP transistors for hobbyists, students, and engineers alike.
