Product Overview
A closer look at VOS618AT as a optocouplers: functional summary, usage notes, and the features that matter in real designs.
- Wide CTR Range (50–600 %): Provides selection flexibility for designers to match input current and drive conditions.
- High Isolation Performance: With 3750 VRMS test rating and robust insulation distances, it delivers reliable electrical separation.
- Compact Packaging, Robust Design: The SSOP-4 package allows integration into dense PCBs while delivering high performance.
The Vishay VOS618AT is the baseline version of the VOS618A series optocoupler: a GaAs IR diode emitter coupled to a silicon planar phototransistor in a SSOP-4 half-pitch package.
While the datasheet lists a generic “VOS618A” (without bin suffix) with CTR 50 %–600 % as the full part number range, the VOS618AT variant follows this naming scheme for the base bin.
It is well suited for applications needing broad CTR flexibility, high isolation and compact packaging.
