General
The TLP3146 photorelay consists of a photo MOSFET optically coupled to an infrared light emitting diode. It is
housed in a 4-pin package with 2.54-mm lead pitch and 2.1-mm height. The low on-state resistance and the high
permissible on-state current make it suitable for power line control applications.

Features
(1) Package: SOP (2.54SOP4) (Height 2.1 mm, pitch 2.54 mm)
(2) Normally opened (1-Form-A)
(3) OFF-state output terminal voltage: 30 V (min)
(4) Trigger LED current: 3 mA (max)
(5) ON-state current: 3.3 A (max)
(6) ON-state resistance: 50 mΩ (max)
(7) Output capacitance: 450 pF (typ.)
(8) Off-state current: 1 μA (max)@VOFF = 30V
(9) Isolation voltage: 1500 Vrms (min)
