Technical details

No last-time-buy or end-of-life notice applies to this date-code window, which simplifies procurement planning for both prototype builds and production runs.

3750Vrms isolation and wide CTR window

Rated for 3750Vrms isolation, this single-channel transistor-output optocoupler suits galvanic isolation in power supplies, motor drives, and industrial interface circuits. The current transfer ratio spans 50% minimum to 600% maximum at a 1mA forward current — a broad window that gives the designer margin when driving logic inputs or low-power loads without needing to overdrive the LED side. Output transistor handles up to 80V and 50mA per channel, with a typical Vce saturation of 400mV.

Temperature range and package for industrial environments

The 4-SOIC body (4.40mm width) with 4-SSOP supplier package footprint is a common pinout shared across many Vishay and compatible optocouplers, simplifying board layout or last-minute substitution review.
