H11A4 [LITE-ON]

The H11Ax family is an industry standard single channel phototransistor coupler. It includes the H11A1, H11A2, H11A3, H11A4, H11A5 couplers. Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor. The isolation performance is accomplished through Vishay double molding isolation manufacturing process. Compliance to DIN EN 60747-5-5 partial discharge isolation specification is available by ordering option 1. These isolation processes and the Vishay ISO9001 quality program results in the highest isolation performance available for a commercial plastic phototransistor optocoupler.
