BC550 Description

Short technical summary and product information.

The BC550 is a general-purpose NPN bipolar junction transistor manufactured by ON Semiconductor. It is designed for low-power amplification and switching applications. Key electrical characteristics include a maximum collector-emitter voltage of 45V, a maximum collector current of 100mA, and a power dissipation of 500mW. The transistor offers a transition frequency of 300MHz and a DC current gain (hFE) of 110 minimum at 2mA collector current and 5V Vce. The collector-emitter saturation voltage is 600mV maximum at 5mA base current and 100mA collector current. The device is housed in a TO-92-3 through-hole package (TO-226-3, TO-92-3), suitable for manual assembly and prototyping. The operating junction temperature range is up to 150°C. It is RoHS3 compliant and has an MSL level of 1 (unlimited). Typical applications include signal amplification, driver stages, and low-current switching in consumer and industrial electronics.
