Overview
The SFH690D-X001T is a single-channel transistor output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a 3750Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device utilizes a 4-SOP (2.54mm) surface-mount package. Key electrical parameters include a maximum collector-emitter saturation voltage of 300mV, a typical forward voltage of 1.15V, and an output current capacity of 50mA. The current transfer ratio ranges from 100% to 300% at a forward current of 5mA.
Feature Summary
- Provides high-voltage isolation capability for signal transmission between isolated circuits
- Utilizes a compact surface-mount package suitable for automated assembly processes
- Features fast switching characteristics with defined rise and fall times
Applications
- General-purpose digital signal isolation in industrial control systems
- Power supply feedback loops requiring galvanic isolation
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the specific suffix X001T against official Vishay documentation to confirm packaging and tape-and-reel specifications. Ensure compliance with RoHS3 standards as indicated in public records. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, general-purpose transistor output isolator is required. The 4-SOP package offers space efficiency compared to DIP variants. Consider the 3750Vrms isolation rating for safety requirements. Verify that the 50mA output current meets the load requirements of the receiving circuitry without exceeding absolute maximum ratings.
Part Context
This component belongs to the SFH690 family of transistor output optocouplers. The family includes variants such as SFH690ABT and SFH690CT, which share similar core isolation technologies but differ in packaging, current transfer ratio grades, or specific electrical tolerances. The SFH690 series is designed for cost-effective isolation solutions in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult official Vishay cross-reference guides or datasheets for verified equivalents.
