Optocoupler with Phototransistor Output

Description

The TCLT10.. Series consists of a phototransistor

optically coupled to a gallium arsenide infrared-

emitting diode in a 4-lead SO6L package.

The elements are mounted on one leadframe using a

coplanar technique, providing a fixed distance

between

input

and

output

for

highest

safety

requirements.

Applications

Circuits

for

safe

protective

separation

against

electrical shock according to safety class II (reinforced

isolation):

For appl. class I –

IV at mains voltage ≤ 300 V

For appl. class I – III at mains voltage

≤ 600 V

according to VDE 0884, table 2, suitable for:

Switch-mode

power

supplies,

line

receiver,

computer peripheral interface, microprocessor

system interface.
