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.
