Description
The TCET1600/ TCET2600/ TCET4600 consists of a phototransistor optically coupled to 2 gallium arsenide infrared-emitting diodes 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 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:

   Computer peripheral interface, microprocessor system interface, telecom equipment.
