BC817K-40HVL

Overview

The BC817K-40H is an NPN general-purpose transistor housed in a small SOT23 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 DC current gain (hFE) ranges from 250 to 600 at VCE = 1 V and IC = 100 mA. The device features high power dissipation capabilities, reaching up to 950 mW on FR4 PCBs with large collector pads, and operates reliably in high-temperature environments up to a junction temperature of 175 °C.

Feature Summary

High-temperature operation capability up to 175 °C
High power dissipation performance
Three distinct current gain selections

Applications

General-purpose switching
Amplification circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact current gain binning and packaging configuration. Ensure that the selected variant aligns with the thermal management requirements of the target application, particularly regarding the maximum junction temperature limits defined in the absolute maximum ratings.

Selection Notes

Select this component when designs require robust high-temperature stability and elevated power handling within a compact SOT23 footprint. The BC817K-40H offers a higher current gain range compared to lower-numbered variants in the series, making it suitable for applications demanding precise control or higher amplification factors without requiring excessive base drive current.

Part Context

This part belongs to the Nexperia BC817KH series, which provides NPN general-purpose transistors in the SOT23 package. The series includes variants with different current gain specifications, such as the BC817K-16H and BC817K-25H. The 'H' designation indicates non-automotive qualification, distinguishing it from automotive-grade alternatives.
