BC857A-7-F

Overview

The BC857A-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 125 to 250 at -2.0 mA and -5 V. Electrical characteristics include a transition frequency of 100 MHz to 200 MHz and a power dissipation capacity of 310 mW. Operating temperatures range from -55°C to +150°C.

Feature Summary

Designed for automatic insertion processes
Complementary to the BC846A-BC848C NPN series
Qualified to JEDEC standards for high reliability

Applications

Switching applications
Audio Frequency (AF) amplifier circuits

Procurement Notes

Verify the specific ordering suffix '-7-F' against official Diodes Incorporated documentation to confirm the standard 3,000-unit reel packaging configuration. Ensure that the component meets RoHS 3 compliance requirements as defined by EU Directive 2015/863. Confirm that the marking code 'K3A' matches the intended production batch specifications.

Selection Notes

Select this component when a PNP transistor with a -45 V collector-emitter breakdown voltage is required. The BC857A variant offers a minimum hFE of 125, suitable for general-purpose amplification. Consider the SOT23 footprint for surface-mount designs requiring compact layouts.

Part Context

This part belongs to the BC856A–BC858C family of PNP small-signal transistors. The 'A' designation indicates a specific DC current gain binning range compared to the 'B' and 'C' variants within the same datasheet. These devices are designed as complementary pairs to the BC846A–BC848C NPN transistors.
