General

The TLP3555A and TLP3555AF photorelay consist of a photo MOSFET optically coupled to an infrared LED. It

is housed in a 4-pin DIP package. The low ON-state resistance and the high permissible ON-state current of the

TLP3555A and TLP3555AF make it suitable for power line control applications.

Features

(1) Normally opened (1-Form-A)
