Single Bipolar Transistors datasheet and documents for 2SB857-B-BP

2SB857-B-BP

Single Bipolar Transistors Overview

The 2SB857-B-BP is a PNP silicon power transistor manufactured by Micro Commercial Components (MCC). It utilizes a TO-220 package with an epoxy body rated UL 94 V-0. The device supports a collector current of -4 A and a collector-emitter voltage of -50 V. Junction temperature ranges from -55 to +150 °C. The 'B' suffix indicates a forward current transfer ratio (hFE) classification of 60 to 120 at -1 A. The '-BP' suffix designates bulk packaging containing 1,000 pieces per box.

Single Bipolar Transistors Feature Summary

Designed for low frequency power amplifier applications
Features a flange-mount TO-220 package for effective heat dissipation
Epoxy casing meets UL 94 V-0 flammability rating
