Overview
The SFH6106-3 is a single-channel surface-mount phototransistor output optocoupler from Vishay. It features an NPN phototransistor with a collector-emitter voltage of 70V and maximum collector current of 100mA. The device provides high isolation voltage of 5300Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a typical forward voltage of 1.65V, maximum forward current of 60mA, and a current transfer ratio ranging from 100% to 200%. Switching characteristics include a typical rise time of 3μs and fall time of 14μs.
Feature Summary
- High current transfer ratio for efficient signal transmission
- Low coupling capacitance ensuring minimal interference
- High isolation voltage for robust safety compliance
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in measurement and testing equipment
- Power supply feedback loops for circuit protection
Procurement Notes
Verify the specific suffix (e.g., -3T vs -3) against official datasheets to ensure correct packaging and CTR binning. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference pinout configurations with your PCB layout to prevent installation errors during surface mount placement.
Selection Notes
Select this component when high isolation voltage and moderate speed are required. Compare current transfer ratio ranges against other SFH6106 variants to match circuit gain requirements. Ensure the surface-mount package fits your board space constraints while maintaining adequate creepage distances for the specified isolation voltage.
Part Context
The SFH6106-3 belongs to the SFH6106 series of surface-mount optocouplers. This family offers alternatives with varying current transfer ratios and packaging options. It serves as a compact solution for isolating low-voltage control circuits from higher voltage loads in modern electronic designs.
Replacement Considerations
SFH6106-1T: Offers lower CTR (40-80%) but faster switching times (2μs/2μs). SFH6106-4T: Provides higher CTR (1.6-320%) with similar isolation. Verify pin compatibility and thermal performance before substitution.
