BC857B-7-F

Overview

The BC857B-7-F is a PNP small-signal transistor manufactured by Diodes Incorporated, housed in an SOT23 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 (hFE) ranging from 220 to 475 at -2.0 mA and -5 V. Power dissipation reaches 310 mW on standard FR-4 PCBs. Operating temperatures span from -55°C to +150°C.

Feature Summary

Designed for automatic insertion processes
Suitable for switching and audio frequency amplifier applications
Fully RoHS compliant and halogen-free

Applications

Switching circuits
Audio frequency amplifiers

Procurement Notes

Verify the specific suffix '-7-F' against official documentation to confirm the 3,000-unit reel packaging format. Ensure the component matches the K3B marking code for the BC857B variant. Confirm compliance with JEDEC standards for high reliability requirements before finalizing procurement specifications.

Selection Notes

Select this component when a PNP transistor with moderate current gain and low power dissipation is required. The SOT23 package facilitates surface-mount assembly. Consider complementary NPN types like the BC847 series if push-pull configurations are needed within the same design architecture.

Part Context

This part belongs to the BC856A–BC858C family of PNP small-signal transistors. It shares the SOT23 form factor with other variants in the series but differs in current gain ranges and breakdown voltages compared to the A and C grades.
