Optocoupler with Phototransistor Output

Description

The TCET110./ TCET2100/ TCET4100 consists of a

phototransistor optically coupled to a gallium arsenide

infrared-emitting diode in a 4-lead up to 16-lead plastic

dual inline package.

The elements are mounted on one leadframe using a

coplanar technique, providing a fixed distance be-

tween

input

and

output

for

highest

safety

requirements.

Applications

Circuits for safe protective separation against electri-

cal shock according to safety class II (reinforced

isolation):

D For appl. class I – IV at mains voltage ≤ 300 V

D For appl. class I – III at mains voltage ≤ 600 V

according to VDE 0884, table 2, suitable for:

Switch-mode power supplies, line receiver, com-

puter

peripheral

interface,

microprocessor

system interface.
