VOS618A-2X001T Vishay VOS618A-2X001T Isolation Optocoupler with Certified Safety Insulation
- Balanced CTR (63–125 %) with Safety Compliance: Offers moderate drive while assuring safe-isolation certification.
- High Isolation Performance: Ensures electrical separation in demanding systems at 3750 VRMS rating.
- Compact Tape-and-Reel Format: “T” suffix allows efficient SMT integration; “X001” ensures agency approved variant.
The Vishay VOS618A-2X001T combines the “-2” CTR bin (63 %–125 %) with the safety option “X001” (option 1 regulatory insulation) and is supplied in tape-and-reel (“T”). This part supports galvanic isolation between input and output circuits with guaranteed insulation performance per agency approvals.
It shares the architecture of the series: GaAs IR diode emitter, silicon planar phototransistor detector, SSOP-4 package.
