BC817K-25H-QR

Overview

The Nexperia BC817K-25H-Q is an NPN general-purpose transistor housed in a small SOT23 (TO-236AB) Surface-Mounted Device plastic 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 range of 160 to 400 at VCE = 1 V and IC = 100 mA. It operates within a junction temperature range up to 175 °C and is qualified according to the AEC-Q101 standard for automotive applications.

Feature Summary

Qualified for automotive applications under the AEC-Q101 standard
High power dissipation capability suitable for demanding thermal environments
Supports high-temperature operation up to 175 °C junction temperature
Offers three distinct current gain selections for design flexibility

Applications

General-purpose switching circuits
Amplification stages
Automotive electronic systems

Procurement Notes

Verify that the specific part number suffix matches the required current gain bin, as the BC817K series offers multiple gain options. Confirm the component meets AEC-Q101 qualification requirements if intended for automotive use. Ensure the ordering code aligns with the desired packaging format and manufacturing site markings specified in the official datasheet.

Selection Notes

Select this component when a robust NPN transistor with high current handling and elevated temperature tolerance is required. The BC817K-25H-Q provides a mid-range current gain profile compared to other variants in the series. Consider the SOT23 package dimensions and thermal resistance characteristics relative to the PCB layout and available cooling methods during the design phase.

Part Context

This component belongs to the BC817KH-Q series, which includes complementary PNP transistors such as the BC807K-25H-Q. The series is designed to provide matched performance characteristics for push-pull or differential amplifier configurations. All members share the same physical footprint and electrical limits, differing primarily in their specified DC current gain ranges.
