BC237 Description

Short technical summary and product information.

The BC237 is an NPN epitaxial silicon bipolar junction transistor manufactured by On Semiconductor (formerly Fairchild Semiconductor). It is designed for general-purpose switching and amplifier applications.

 

Key electrical characteristics include a minimum collector-emitter breakdown voltage (BVCEO) of 45V, a maximum collector current of 100mA, and a maximum power dissipation of 500mW. The DC current gain (hFE) is a minimum of 120 at 2mA collector current and 5V collector-emitter voltage. The current gain bandwidth product (fT) is typically 150MHz at 3V and 0.5mA, and 85MHz at 5V and 10mA. The output capacitance (Cob) is typically 3.5pF.

 

The device is housed in a through-hole TO-92 (TO-226) package with three leads. It supports an operating junction temperature range of -55°C to 150°C.
