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
RMS
Isolation Test Voltage. This isolation performance
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-
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.
