Overview
The SFH620AGB-X019T is a single-channel optoisolator featuring an NPN phototransistor output and SMD-4 package. It provides 5300 Vrms isolation voltage with a current transfer ratio ranging from 100% to 600%. Key electrical parameters include a maximum forward voltage of 1.65V, max input current of 60mA, and collector-emitter saturation voltage of 400mV. Rise and fall times are both 2µs. The device supports a maximum collector current of 100mA and operates within a temperature range of -5°C to +100°C.
Feature Summary
- High isolation voltage capability for safety-critical applications
- Fast switching performance with microsecond rise and fall times
- Wide current transfer ratio range for flexible signal coupling
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated ground planes
Procurement Notes
Verify the specific suffix X019T against official Vishay documentation to confirm packaging type and tape/reel specifications. Ensure the component matches the required SMD footprint and pin configuration for your PCB layout. Cross-reference the CTR binning requirements with your circuit design needs before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and fast response are critical. The wide CTR range accommodates varying input drive conditions. Ensure thermal management accounts for the 150mW power dissipation rating. Verify compatibility with surface mount assembly processes due to the SMD-4 package format.
Part Context
This part belongs to Vishay's SFH series of optocouplers, designed for general-purpose isolation tasks. The SFH620AGB variant offers transistor output characteristics suitable for digital signal transmission. The X019T suffix typically denotes specific packaging or handling configurations provided by the manufacturer.
Replacement Considerations
Direct substitutes may include other Vishay SFH620 series variants with compatible pinouts and electrical ratings. Verify isolation voltage and CTR ranges match application requirements when considering alternative models.
