Overview
The Diotec Semiconductor BC817K-16 is a single NPN general-purpose transistor housed in an SOT-23 (TO-236) surface-mount package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current rating of 500 mA, with peak currents reaching 1 A. The device offers a DC current gain (hFE) range of 100 to 250 at IC = 100 mA and VCE = 1 V. Key electrical parameters include a power dissipation of up to 500 mW on a PCB, a transition frequency of 170 MHz, and a collector-base cutoff current of 100 nA.
Feature Summary
- Low thermal resistance construction for efficient heat dissipation
- Three distinct current gain groups available for precise circuit matching
- Compliant with RoHS, REACH, and Conflict Minerals regulations
Applications
- Signal processing circuits
- General-purpose switching applications
- Amplification stages
Procurement Notes
Verify the specific suffix against official documentation to confirm compliance status. Standard versions are commercial/industrial grade, while -Q and -AQ suffixes denote AEC-Q101 compliance or qualification. Confirm mechanical data such as tape and reel dimensions if automated assembly is required.
Selection Notes
Select this component when low thermal resistance and standardized gain grouping are required. The BC817K-16 provides a defined hFE window suitable for consistent amplification performance. Ensure the design accommodates the 45 V collector-emitter breakdown and 500 mA continuous current limits under specified thermal conditions.
Part Context
This part belongs to the BC817K series of SMD general-purpose NPN transistors manufactured by Diotec Semiconductor. The 'K' designation indicates enhanced thermal characteristics compared to standard variants. The series includes complementary PNP transistors and is designed for surface-mount technology in compact electronic assemblies.

FAQ
What marking code corresponds to the BC817K-16?
The BC817K-16 is marked with either '6A' or '6CR'.
How does the BC817K-16 differ from the standard BC817-16?
The BC817K-16 features lower thermal resistance and supports higher power dissipation (up to 500 mW with adequate copper pads) compared to standard versions.
Is the BC817K-16 suitable for automotive applications?
Standard BC817K-16 units are commercial/industrial grade. Automotive suitability requires the -Q (compliant) or -AQ (qualified) suffixes which meet AEC-Q101 standards.
