DESCRIPTION

The TCET111., TCET111.G consists of a phototransistor

optically coupled to a gallium arsenide infrared-emitting

diode in a 4 pin plastic dual inline package.

APPLICATIONS

Circuits for safe protective separation against electrical

shock according to safety class II (reinforced isolation):

• for appl. class I to IV at mains voltage

 300 V

• for appl. class I to III at mains voltage

 600 V according

to DIN EN 60747-5-5 (VDE 0884), suitable for:

- Switch-mode power supplies

- Line receiver

- Computer peripheral interface

- Microprocessor system interface

FEATURES

• CTR offered in 9 groups

• Isolation materials according to UL 94 V-0

• Pollution degree 2



(DIN / VDE 0110 / resp. IEC 60664)

• Climatic classification 55 / 100 / 21



(IEC 60068 part 1)

• Special construction: therefore, extra low coupling

capacity of typical 0.2 pF, high common mode rejection

• Low temperature coefficient of CTR

• Temperature range -40 °C to +110 °C

• Rated
