General
The TOSHIBA TLP3109A photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is
housed in a 2.54SOP6 package. The low ON-state resistance and the high permissible ON-state current of the
TLP3109A make it suitable for power line control applications.

Features
(1) Normally opened (1-Form-A)
(2) OFF-state output terminal voltage: 100 V (min)
(3) Trigger LED current: 3 mA (max)
(4) ON-state current: 3 A (max) (A connection)
(5) ON-state resistance: 65 mΩ (max) (A connection)
(6) Isolation voltage: 1500 Vrms (min)
(7) Safety standards
