BC547CTA Description

Short technical summary and product information.

The BC547CTA is a general-purpose NPN bipolar junction transistor manufactured by ON Semiconductor. It is designed for low-power amplification and switching applications.

 

Key electrical specifications include a collector-emitter voltage (Vceo) of 45V, a continuous collector current (Ic) of 100mA, and a power dissipation (Pd) of 500mW. The transistor offers a transition frequency (ft) of 300MHz, making it suitable for moderate-speed switching and amplification up to VHF frequencies. The DC current gain (hFE) is a minimum of 420 at 2mA collector current and 5V Vce, ensuring consistent performance in linear circuits. The collector-emitter saturation voltage is a maximum of 600mV at 100mA collector current and 5mA base current.

 

The device is housed in a TO-226-3 / TO-92-3 (TO-226AA) package with formed leads, designed for through-hole mounting. The operating junction temperature is rated up to 150°C. The BC547CTA is RoHS3 compliant and has an MSL of 1 (unlimited).
