BC817-25W-QF

Overview

The BC817-25W-Q is an NPN general-purpose transistor from the Nexperia BC817W-Q series, housed in a SOT323 (SC-70) surface-mount package. It supports a collector-emitter voltage of 45 V and a continuous collector current of 500 mA, with a peak pulse current capability of 1 A. The device features a DC current gain (hFE) range of 160 to 400 at IC = 100 mA and VCE = 1 V. It operates within a junction temperature range of -65 °C to 150 °C and has been qualified according to the AEC-Q101 standard for automotive applications.

Feature Summary

• Qualified according to AEC-Q101 standards for automotive use
• High current handling capability up to 500 mA
• Three distinct current gain selections available

Applications

• General-purpose switching
• Amplification circuits
• Automotive electronics

Procurement Notes

Verify the specific ordering code against the manufacturer's official database to ensure correct suffix alignment. Confirm that the component meets the required AEC-Q101 qualification status if intended for automotive deployment. Cross-reference the marking code '6B' followed by a manufacturing site placeholder to validate authenticity upon receipt.

Selection Notes

Select this variant when a moderate DC current gain between 160 and 400 is required for signal amplification or switching tasks. The SOT323 package offers a compact footprint suitable for space-constrained designs. Ensure thermal management accounts for the power dissipation limits defined in the datasheet under specific PCB mounting conditions.

Part Context

This component belongs to the BC817W-Q series of NPN transistors designed for robust performance in demanding environments. The series includes variants with different gain ranges (BC817-16W-Q, BC817-25W-Q, BC817-40W-Q) to accommodate various circuit requirements while maintaining a standardized pinout and package geometry.

Replacement Considerations

Direct functional substitutes within the same family include BC817-16W-Q and BC817-40W-Q, provided their respective hFE ranges align with design specifications. Non-series equivalents require verification of voltage, current, and gain parameters.
