BC546CTA Description

Short technical summary and product information.

The BC546CTA is an NPN bipolar junction transistor manufactured by ON Semiconductor. Designed for general purpose amplification and switching applications, it offers reliable performance in low-power circuits.

 

Electrical characteristics include a maximum collector-emitter voltage of 65V and a maximum collector current of 100mA. The device features a minimum DC current gain (hFE) of 420 at 2mA collector current and 5V collector-emitter voltage, with a maximum saturation voltage of 600mV at 5mA base current and 100mA collector current. It has a typical transition frequency of 300MHz and a maximum power dissipation of 500mW.

 

The transistor is supplied in a through-hole TO-92-3 package, suitable for PCB mounting and prototyping. It can operate at a maximum junction temperature of 150°C. Compliance data indicates RoHS3, MSL 1, and REACH unaffected status, though these are unverified. For design validation, refer to the manufacturer's official datasheet.
