Overview
The BC817K-16R is an NPN general-purpose transistor from the Nexperia BC817K series, 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. The device offers three current gain selections; the -16 variant provides a DC current gain range of 100 to 250 at VCE = 1 V and IC = 100 mA. It features high power dissipation capability and is qualified according to AEC-Q101 standards for automotive applications.
Feature Summary
- Three distinct current gain selections available within the series
- High power dissipation capability for robust thermal performance
- Qualified for automotive applications under AEC-Q101 standards
Applications
- General-purpose switching circuits
- Amplification stages
- Automotive electronic systems
Procurement Notes
Verify the specific ordering suffix 'R' against official Nexperia documentation to confirm reel packaging specifications. Ensure the selected part number matches the required current gain bin (-16). Confirm that the SOT23 package footprint aligns with the target PCB design constraints before finalizing procurement orders.
Selection Notes
Select the BC817K-16R when a low-to-moderate DC current gain (100–250) is required for precise biasing control. This variant is suitable for designs where higher gain options like the -25 or -40 would cause instability. Verify that the 45 V collector-emitter voltage rating exceeds the maximum circuit operating voltage under all transient conditions.
Part Context
This component belongs to the BC817K series of NPN general-purpose transistors manufactured by Nexperia. The series includes complementary PNP devices such as the BC807K-16. All variants share the same SOT23 package and electrical limits, differing primarily in their specified DC current gain ranges to accommodate various circuit amplification requirements.
