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)

Vpd = 1.6 kV

? Rated isolation voltage (RMS includes DC)

VIOWM = 600 VRMS

? Rated recurring peak voltage (repetitive) VIORM = 850 Vpeak

? Creepage current resistance according to VDE 0303/

IEC 60112 comparative tracking index: CTI ? 175

? Thickness through insulation ? 4 mm

? External creepage distance > 8 mm

? Material categorization: for definitions of compliance
