Micro Commercial Components Corp. Single Bipolar Transistors BC857B-13P

The BC857B is a PNP silicon transistor designed for switching and audio frequency amplifier applications, available in a SOT-23 package. It features a collector-emitter voltage rating of -45 V, a collector current of -100 mA, and a power dissipation of 310 mW at 50°C. The device supports a junction temperature range of -55°C to +150°C and has thermal resistances of 320°C/W (junction to solder point) and 403°C/W (junction to ambient). The DC current gain (hFE) ranges from 220 to 475 at -5 V collector-emitter voltage and -2 mA collector current. The transistor is RoHS compliant, halogen-free, meets UL 94 V-0 flammability rating, and is moisture sensitivity level 1. The -13P suffix indicates tape and reel packaging of 10,000 pieces per reel.
