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
with a 5300 V
Isolation Test Voltage. This isolation performance
RMS
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
®
(TRIOS) on the phototransistor substrate. These isolation pro-
Notes:
cesses and the Infineon IS09001 Quality program results in the
highest isolation performance available for a commercial plastic
phototransistor optocoupler.
Designing with data sheet is covered in Application Note 45.
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.
