Standard Single Channel Phototransistor Couplers. The MCT2/ MCTE household is the Industry Standard Single Channel Phototransistor . Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor. Listed to abide by a 5300 VRMS isolation test voltage. This isolation performance is accomplished through Double molding isolation manufacturing process. Compliance to DIN EN 60747-5-2(VDE0884)/ DIN EN 60747-5-5 pending discharge isolation By ordering, specification can be obtained for all these families option 1. These isolation processes and the Vishay ISO9001 Quality program results in the isolation performance Accessible for a industrial phototransistor optocoupler. The devices are available in lead Suitable for surface mounting and are readily available Either on tape and reel, or at tube shipping containers.
