Overview
The Diotec Semiconductor BC817K-40R13 is an SMD general-purpose NPN transistor housed in a SOT-23 package. It features a maximum collector-emitter voltage (VCEO) of 45 V and a continuous DC collector current (IC) of 500 mA. The device offers three current gain groups, with the -40 suffix indicating a minimum hFE of 250 at IC = 100 mA. Power dissipation reaches 500 mW on a PCB with 3 mm² copper pads. Peak collector current is rated at 1 A, and the junction temperature range spans from -55°C to +150°C.
Feature Summary
- Low thermal resistance design for efficient heat dissipation
- Three distinct current gain groups for precise amplification control
- Compliant with RoHS, REACH, and Conflict Minerals regulations
Applications
- Signal processing circuits
- General switching applications
- Amplification stages
Procurement Notes
