Product Overview

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 is 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. The devices are available in lead formed configuration suitable for surface mounting and are available either on tape and reel, or in standard tube shipping containers.
