Overview
The SFH6186-2T is a single-channel surface-mount phototransistor optocoupler from Vishay. It features an NPN phototransistor output with a current transfer ratio of 63% to 125%. The device provides high isolation voltage of 4420Vrms and operates within a temperature range of -55°C to 100°C. Typical switching times are 3.5μs rise and 5μs fall. It is packaged in a compact 4-SMD configuration suitable for automated assembly.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Compact surface-mount package design facilitating automated PCB assembly
- Wide operating temperature range ensuring reliability in harsh environments
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits in measurement technology
- Power supply feedback loops for safety compliance
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the CTR bin (63-125%) matches circuit requirements. Check RoHS compliance status as per latest datasheet revisions. Ensure ESD handling procedures are followed during storage and assembly.
Selection Notes
Select this component for applications needing moderate speed and high isolation. Compare CTR ranges against other SFH6186 variants if higher gain is required. Verify package dimensions against board space constraints. Consider thermal management needs given the 100°C maximum junction temperature limit.
Part Context
Part of the SFH6186 series, designed for general-purpose isolation. Shares common electrical characteristics with DIP versions but offers SMD advantages. Used in conjunction with standard LED drivers and phototransistor loads. Complements Vishay's broader optoelectronics portfolio for system integration.
Replacement Considerations
SFH6186-2 is the through-hole equivalent. SFH6186-3T offers higher CTR (100-200%). Verify pinout compatibility before substitution. Check isolation voltage ratings match application safety standards.
