Overview
The SFH608-4X007T is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a transistor output with base access. It provides 5300Vrms isolation voltage and utilizes a 6-SMD surface-mount package. The device supports DC input and offers a minimum current transfer ratio of 160% at 10mA forward current. Key electrical parameters include a maximum collector-emitter saturation voltage of 400mV, a typical forward voltage of 1.2V, and a maximum DC forward current of 60mA. It operates within a temperature range of -55°C to 100°C.
Feature Summary
- High current transfer ratio capability at low input currents
- Transistor output configuration with accessible base terminal
- Robust 5300Vrms insulation voltage for safety isolation
Applications
- General purpose signal isolation in industrial control systems
- Interface circuits requiring high current gain
- Power supply feedback loops
Procurement Notes
Verify the specific suffix '4X007T' against the official Vishay datasheet to confirm packaging and tape/reel specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity level (MSL 1) requirements for storage and handling during assembly processes.
Selection Notes
Select this component when a high current transfer ratio is required relative to the input drive current. The integrated base allows for external biasing or speed adjustment. Compare the 5300Vrms isolation rating against system safety requirements and ensure the 6-SMD footprint fits the PCB layout constraints.
Part Context
This part belongs to the SFH608 series of Vishay's optocoupler family, designed specifically for applications demanding high linearity and current transfer efficiency. The series typically features a gallium arsenide LED coupled to an NPN phototransistor, optimized for performance in compact surface-mount designs.
Replacement Considerations
Consult the official Vishay cross-reference documentation for verified substitutes. Generic equivalents may differ in current transfer ratio or isolation voltage ratings; verify all critical parameters before substitution.
