Overview
The BC817K-25VL is an NPN general-purpose transistor from the Nexperia BC817K series, housed in a small SOT23 (TO-236AB) surface-mount plastic package. It supports a maximum collector-emitter voltage of 45 V and a continuous collector current of 500 mA. The device offers a peak collector current capability of 1 A for single pulses up to 1 ms. DC current gain (hFE) ranges from 160 to 400 at VCE = 1 V and IC = 100 mA. Total power dissipation reaches 350 mW at Tamb ≤ 25 °C. Transition frequency is rated at 100 MHz.
Feature Summary
- Three distinct current gain selections available within the series
- High power dissipation capability for efficient thermal management
- Qualified according to AEC-Q101 automotive standards
Applications
- General-purpose switching circuits
- Amplification applications
- Automotive electronics systems
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the component meets AEC-Q101 requirements if deployed in automotive environments. Cross-reference marking codes with datasheet tables to validate manufacturing origin and authenticity before integration into production designs.
Selection Notes
Select this variant when a moderate DC current gain range between 160 and 400 is required. The SOT23 package provides space efficiency for dense PCB layouts. Consider the 45 V rating for low-voltage logic interfacing. Evaluate thermal resistance values based on the specific PCB copper layer configuration and mounting pad size used in the design.
Part Context
This component belongs to the BC817K series of NPN transistors designed for high-current applications. It serves as the complement to the BC807K PNP series. The K-series designation indicates qualification for automotive use under AEC-Q101 standards. It shares the same physical footprint as standard BC817 devices but offers enhanced reliability specifications.
