TCDT1120(G) Series
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The TCDT1 120(G) series consists of a phototransistor optically coupled to a gallium arsenide
infrared-emitting diode in a 6-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.
