Optocoupler with Phototransistor Output

Description

The

TCET120./

TCET2200

consists

of

a

phototransistor optically coupled to a gallium arsenide

infrared-emitting diode in a 4-lead up to 8-lead plastic

dual inline 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):

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,

computer peripheral interface, microprocessor

system interface.
