DESCRIPTION

This data sheet presents five families of Infineon Industry Standard

Single Channel Phototransistor Couplers. These families include the

4N25/26/27/28 types, the 4N35/36/37/38 couplers, the H11A1/A2/

A3/A4/A5, the MCT2/2E, and MCT270/271/272/273/274/275/276/

277 devices.Each optocoupler consists of Gallium Arsenide infra-

red LED and a silicon NPN phototransistor.

These couplers are Underwriters Laboratories (UL) listed to comply

is accomplished through Infineon double molding isolation manu-

facturing process. Compliance to VDE 0884 partial discharge isola-

tion specification is available for these families by ordering option 1.

Phototransistor gain stability, in the presence of high isolation volt-

ages, is insured by incorporating a TRansparent lOn Shield

cesses and the Infineon IS09001 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.
