Description
The OPI120TX and OPI120TXV are optically coupled isolators, each consisting of a gallium aluminum arsenide infrared light emitting diode (OP235TX or OP235TXV) and an NPN silicon phototransistor (OP804TX or OP804TXV) sealed in a high dielectric plastic housing. This series is designed for applications requiring high voltage isolation between input and output.

Features
• High current transfer ratio
• 15 kV electrical isolation
• Base lead provided for conventional transistor biasing
• Components processed to Optek’s screening program patterned after MIL-PRF-19500 for TX and TXV devices
