BC546 NPN Transistor: Equivalents, Datasheet, and Pinout

The BC546 is a high-frequency NPN transistor commonly used in low noise amplifier designs. It has a maximum gain value of 800 and a high collector to emitter voltage of 65V, making it suitable for high voltage audio and signal amplifier applications. The maximum load the BC546 allows is 100mA, which is an ideal value to drive relays, LEDs, ICs, and other transistors, etc.

The BC546 is manufactured in four different part numbers: BC546, BC546A, BC546B, and BC546C. The only difference between these four part numbers is their DC current gain value. For example, BC546's current gain value is from 110 to 800, BC546A is from 110 to 220, BC546B is from 200 to 450, and BC546C is from 420 to 800.
