BC817-25QB-QZ

Overview

The Nexperia BC817-25QB-QZ is an NPN general-purpose transistor in the DFN1110D-3 (SOT8015) leadless package. It features a collector-emitter voltage of 45 V, a continuous collector current of 500 mA, and a peak pulse current of 1 A. The DC current gain ranges from 160 to 400 at IC = 100 mA. Total power dissipation reaches 350 mW on a 35 μm copper PCB. Qualified under AEC-Q101, it operates between -55 °C and +150 °C.

Feature Summary

Ultra-thin DFN1110D-3 package with side-wettable flanks for Automatic Optical Inspection
Automotive qualification compliant with AEC-Q101 standards
High current capability with three distinct current gain selections

Applications

General-purpose switching and amplification
Space-restricted electronic designs

Procurement Notes

Verify the specific suffix 'QZ' against official Nexperia documentation to confirm tape-and-reel packaging details. Ensure the component matches the DFN1110D-3 footprint dimensions and pinout configuration before integration into the printed circuit board layout.

Selection Notes

Select this component when automotive reliability and compact form factors are required. The DFN1110D-3 package offers a smaller footprint than traditional SOT-23 devices while maintaining high thermal performance suitable for dense surface-mount assemblies.

Part Context

This device belongs to the BC817QB-Q series, which includes variants with different current gain ranges: BC817-16QB-Q (100-250), BC817-25QB-Q (160-400), and BC817-40QB-Q (250-600). All share identical electrical ratings and package geometry.

Replacement Considerations

Direct substitutes include BC817-25QB-Q and BC807-25QB-Q. Verify that alternative packages like SOT-23 or DFN1010D-3 meet the spatial and thermal requirements of the design.
