The BC857 is a PNP bipolar junction transistor designed for switching and audio frequency amplifier applications in a SOT-23 package measuring 3.00 mm by 1.40 mm by 1.15 mm. It has a collector-emitter voltage rating of -45 V, a collector current rating of -0.1 A, and a maximum power dissipation of 200 mW. The device features a thermal resistance of 625 °C/W and a junction temperature limit of 150 °C. Current gain (hFE) ranges from 220 to 475 for the BC857B variant under test conditions of -5 V collector-emitter voltage and -2 mA collector current. Collector-emitter saturation voltage is -0.5 V at -100 mA collector current and -5 mA base current. Transition frequency is 100 MHz. The part meets RoHS standards and is packaged in SOT-23 with a noted compliance to AEC-Q200 for automotive applications.
