Description

The MCT27x family is an Industry Standard Single

Channel Phototransistor Couplers. It includes the

MCT270/ 271/ 272/ 273/ 274/ 275/ 276/ 277 couplers.

Each optocoupler consists of gallium arsenide infra-

red LED and a silicon NPN phototransistor.

These couplers are Underwriters Laboratories (UL)

age.

This isolation performance is accomplished through

Vishay double molding isolation manufacturing pro-

cess. Compliance to DIN EN 60747-5-2(VDE0884)/

DIN EN 60747-5-5 pending partial discharge isolation

specification is available by ordering option 1.

These isolation processes and the Vishay ISO9001

quality program results in the highest isolation perfor-

mance available for a commercial plastic phototrans-

istor optocoupler.

The devices are available also in lead formed config-

uration suitable for surface mounting and are avail-

able either on tape and reel, or in standard tube

shipping containers.
