BC857BSHF

Overview

The Nexperia BC857BSHF is a PNP/PNP matched double transistor housed in an SOT363-3 (SC-88) surface-mount package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA per transistor. The device has a total power dissipation of 200 mW at 25°C, with a maximum operating temperature of 150°C and a storage range from -65°C to +150°C. Key electrical parameters include a minimum DC current gain (hFE) of 200 and a transition frequency (fT) of 100 MHz. The component complies with RoHS standards and is designed for general-purpose switching and amplification applications.

Feature Summary

• Matched PNP/PNP configuration ensures consistent performance between transistors
• Ultra-small SC-88 plastic package reduces board space requirements
• High thermal stability supports operation up to 150°C junction temperature

Applications

• General purpose switching circuits
• Signal amplification stages
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix 'SHF' against official Nexperia documentation to confirm tape and reel packaging specifications. Ensure compatibility with standard pick-and-place equipment due to the small SC-88 footprint. Confirm RoHS compliance status through the manufacturer's latest declaration before integration into regulated products.

Selection Notes

Select this component when a matched PNP pair is required in a minimal footprint. Compare hFE binning requirements against circuit sensitivity. Verify that the 45V voltage rating exceeds the maximum expected load voltage. Consider thermal management strategies given the 200mW total power dissipation limit in the small package.

Part Context

This part belongs to the BC857 series of small-signal PNP transistors. It serves as the dual-transistor complement to single-unit variants like the BC857B. The SC-88 package offers a compact alternative to larger SOT-23 configurations while maintaining similar electrical characteristics for space-constrained designs.

Replacement Considerations

BC857BSH-Q is a qualified automotive-grade alternative within the same family. Standard BC857BS variants may serve as functional replacements if automotive qualification is not required. Verify pinout compatibility and hFE matching tolerances before substitution.
