BC817K-16-QR

Overview

The BC817K-16-QR is a single NPN general-purpose transistor manufactured by Nexperia. It operates within a collector-emitter voltage (VCEO) of 45 V and supports a continuous collector current (IC) of 500 mA. The device utilizes an SOT-23 (TO-236AB) surface-mount package with three pins. Key electrical characteristics include a maximum collector-base voltage (VCBO) of 50 V, a maximum emitter-base voltage (VEBO) of 5 V, and a total power dissipation (Pd) of 350 mW. The minimum DC current gain (hFE) for the -16 grade is 100 at IC=100mA, VCE=1V. The transition frequency (fT) is typically 100 MHz. Operating temperatures range from -65°C to +150°C.

Feature Summary

• High current capability suitable for switching applications
• Three available current gain selections for design flexibility
• AEC-Q101 qualified for automotive reliability standards

Applications

• General-purpose switching circuits
• Amplification stages in audio or signal processing
• Automotive electronic systems requiring AEC-Q101 compliance

Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm tape-and-reel packaging specifications and exact binning parameters. Ensure the selected component matches the required hFE grading (-16) and that the source provides valid traceability records for automotive-grade parts.

Selection Notes

Select this component when a small SOT-23 footprint is required alongside high current handling up to 500 mA. The -16 gain bin offers a standard amplification range. Consider the complementary BC807K-16-QR for push-pull configurations. Verify thermal management requirements given the 350 mW power dissipation limit in the specified package.

Part Context

This part belongs to the BC817 series of NPN transistors, which are widely used as general-purpose devices. The series includes variants like BC817-16, BC817-25, and BC817-40, differentiated primarily by their DC current gain ranges. The BC817K variant specifically denotes automotive qualification under AEC-Q101 standards, ensuring higher reliability for vehicle electronics compared to standard commercial grades.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified NPN transistors in SOT-23 packages with similar 45V/500mA ratings, such as the BC817-16-QR or equivalent parts from other manufacturers meeting the same electrical and automotive standards.
