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
