Single Bipolar Transistors datasheet and documents for BC557BG

BC557BG

Single Bipolar Transistors Overview

The BC557BG is a PNP silicon epitaxial planar transistor manufactured by onsemi in a TO-92 (TO-226) plastic package. It features a collector-emitter voltage of -45 V and a continuous collector current of -100 mA. The device provides a DC current gain range of 120 to 460 at -10 mA, with a typical current-gain bandwidth product of 320 MHz. Thermal resistance from junction to ambient is 200 °C/W, supporting operation within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

PNP silicon epitaxial planar construction for amplifier applications
High-voltage capability with -45 V collector-emitter breakdown
Lead-free packaging available compliant with environmental standards

Single Bipolar Transistors Applications

General-purpose switching circuits
Audio frequency amplification stages
Complementary pairing with NPN transistors such as the BC547 series

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix BG corresponds to the specific bulk packaging configuration listed in the official documentation. Confirm lead-free status and pinout style 17 (Collector-Base-Emitter) matches the target circuit design requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate voltage ratings and standard TO-92 form factor is required. Ensure the application operates within the specified thermal limits and accounts for the variation in DC current gain across the B-series range during circuit design.

Single Bipolar Transistors Part Context

This part belongs to the BC55x family of general-purpose amplifier transistors produced by onsemi. It serves as the PNP counterpart to the BC547 series and shares similar physical dimensions and electrical characteristics with other variants like the BC557B, differing primarily in packaging and gain binning specifications.
