Product Details

BC327 PNP Transistor - General-Purpose Switching & Amplification

The BC327 is a PNP bipolar junction transistor (BJT) in a TO-92 package, commonly used for general-purpose switching and amplification tasks requiring higher current handling than typical small-signal transistors. It is the classic PNP complement in many hobbyist and repair projects where a BC337 or similar NPN is used on the other side of the circuit.

Functions & Applications

Higher Current Rating: Handles up to 800mA, suitable for driving small relays, motors and LED strips directly.
Standard TO-92 Package: Compact through-hole design, easy to solder on breadboards and prototyping boards.
PNP Polarity: Ideal for high-side switching and complementary push-pull output stages alongside NPN transistors.
General Purpose: Works well in both linear amplification and switching applications.

Frequently Asked Questions

Q: What is the complementary NPN part for BC327?
A: The complementary NPN transistor is the BC337, commonly used together in push-pull or high/low-side switching designs.

Q: Can the BC327 drive a small 12V relay?
A: Yes, as long as the relay coil current stays below 800mA (Ic). Use a flyback diode across the coil to protect the transistor.

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