BC237B Description

Short technical summary and product information.

The BC237B is an NPN bipolar junction transistor manufactured by On Semiconductor. It features a collector-emitter breakdown voltage of 45V and a continuous collector current rating of 100mA, with a power dissipation of 500mW. The transistor offers a DC current gain (hFE) of 180 minimum at 2mA collector current and 5V collector-emitter voltage, and a transition frequency of 250MHz, making it suitable for general-purpose switching and amplification applications. The device is housed in a through-hole TO-92-3 package (TO-226-3, TO-92-3 (TO-226AA)), with an operating junction temperature up to 150°C. It is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified. The BC237B is commonly used in low-power signal processing, driver stages, and switching circuits.
