BC857C Description

Short technical summary and product information.

The BC857C is a PNP bipolar junction transistor designed for general purpose switching and amplification applications. It is part of the BC857 series from Diotec Semiconductor, offering a high DC current gain (hFE) of 420 minimum at 2mA, 5V. The transistor is rated for a maximum collector-emitter voltage of 45V and a continuous collector current of 100mA, with a peak current capability of 200mA. Power dissipation is limited to 250mW, and the junction temperature range is -55°C to 150°C. The device is housed in a surface mount SOT-23 package (also known as TO-236-3 or SC-59), making it suitable for compact PCB designs. It is available in tape and reel packaging with 3000 units per 7-inch reel. The BC857C is compliant with RoHS, REACH, and Conflict Minerals regulations, and has an MSL of 1. Typical applications include signal processing, switching circuits, and amplification stages in consumer and industrial electronics.
