DESCRIPTION

The H11A1 is an industry standard single channel

phototransistor coupler.

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.

Note

? Designing with data sheet is covered in Application Note 45.
