VOS618A-7T Vishay VOS618A-7T Mid-CTR Signal-Isolation Optocoupler for Compact Electronics
- Mid-Range CTR (80–160 %): Well matched for designs with moderate LED drive and cost-sensitive requirements.
- High Isolation Assurance: 3750 VRMS isolation ensures safe separation between input/output circuits in noisy or high-voltage environments.
- Space-Efficient Packaging: The SSOP-4 format allows minimal board real estate while delivering full isolation performance.
The Vishay VOS618A-7T is another variant in the VOS618A series packaged in SSOP-4 half-pitch format. For this “-7” bin, the CTR is specified at 80 % to 160 % (IF = 1 mA, VCE = 5 V).
Designed to transfer signals between two electrically isolated circuits, it provides high isolation voltage, low coupling capacitance, and compact packaging suitable for modern electronic systems.
