1. Anode

2. Cathode

3. Emitter

4. Collector

Features

1. Opaque type, mini-flat package.

2. Subminiature type

(The volume is smaller than that of our conventional DIP type by

as far as 30%).

3. Current transfer ratio

4. Isolation voltage between input and output (Viso:3750Vrms).

Applications

1. Hybrid substrates that reguire high density mounting.

2. Programmable controllers.
