Vishay Semiconductors VORA1150 Solid State Relay

Vishay Semiconductors VORA1150 Solid State Relay is an AEC-Q102 qualified 1 form A solid-state relay in an innovative 4-pin SMD-8 package. This relay consists of an infrared emitter that is optically coupled to high-voltage MOSFETs between the output terminals. The VORA1150 solid-state relay features 1500V load voltage, 50mA load current, and 100Ω typical on-resistance. This relay provides reinforced isolation and is RoHS compliant. Typical applications include battery isolation measurement in electric vehicles, pre-charge relay, on-board charger, battery management system, and solar panel leakage current detection.
