Overview
The SFH6156-3X001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70 V and a maximum collector current of 100 mA. The device provides an isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.65 V, and a collector-emitter saturation voltage of 400 mV. The Current Transfer Ratio (CTR) ranges from 100% to 200%. Typical switching times are 3 µs for rise time and 14 µs for fall time.
Feature Summary
- High insulation voltage capability of 5300 Vrms for robust signal isolation
- Wide operating temperature range supporting extreme environmental conditions
- High current transfer ratio ensuring efficient signal transmission
- Surface-mount SMD-4 package design for compact integration
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal isolation in microprocessor interfaces
Procurement Notes
Verify the specific suffix X001 against official Vishay documentation to confirm packaging type and CTR binning. Ensure compatibility with surface mount assembly processes. Cross-reference datasheet revisions for any changes in mechanical dimensions or electrical limits before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required. The NPN phototransistor output suits applications needing standard logic interfacing. Verify that the 100-200% CTR range meets the specific circuit gain requirements. Confirm that the 4-SMD footprint aligns with the target PCB layout constraints.
Part Context
This part belongs to the SFH6156 series of high-speed, high-reliability optocouplers. The series offers various CTR bins and packaging options. The SFH6156-3 variant specifically denotes the 100-200% CTR range. The X001 suffix typically indicates tube packaging, distinguishing it from tape-and-reel variants like X001T.
Replacement Considerations
Check for direct substitutes within the SFH6156 family such as SFH6156-1X001 or SFH6156-2X001 if different CTR bins are acceptable. Verify pinout compatibility and thermal characteristics before substituting.
