BC557B,112 Description

Short technical summary and product information.

The BC557B,112 is a PNP general purpose bipolar junction transistor manufactured by NXP Semiconductors. It is designed for low-current switching and amplification applications.

 

Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 45V, a collector current (IC) rating of 100mA (200mA peak), and a DC current gain (hFE) range of 220 to 475 at 2mA and 5V. The transistor features a transition frequency (ft) of 100MHz and a typical noise figure of 2dB, making it suitable for audio and low-frequency signal processing.

 

The device is housed in a TO-226-3 / TO-92-3 (TO-226AA) formed leads package with through-hole mounting. It has a maximum power dissipation of 500mW and a junction temperature rating of 150°C. The thermal resistance from junction to ambient is 250 K/W.
