BC238A Description

Short technical summary and product information.

The BC238A is an NPN bipolar junction transistor manufactured by onsemi. It features a maximum collector-emitter breakdown voltage of 25V and a maximum collector current of 100mA, with a power dissipation rating of 500mW. The transistor has a minimum DC current gain (hFE) of 120 at Ic=2mA and Vce=5V, and a maximum collector-emitter saturation voltage of 600mV at Ib=5mA and Ic=100mA. With a transition frequency of 250MHz, it is suitable for low-frequency amplification and switching applications.

 

The device is housed in a through-hole TO-92-3 package (also referred to as TO-226-3 or TO-226AA). It supports a maximum operating junction temperature of 150°C. The BC238A is designed for general-purpose use in consumer electronics, signal processing, and low-power driver circuits. No additional heat sinking is required for typical operation within its ratings.
