General
The TLP3409S photorelay consists of a photo MOSFET optically coupled to an infrared light emitting diode. It
is housed in a S-VSON4 package. The TLP3409S features a very small on-resistance and on/off switching of
current as high as 0.65 A, making it ideal for switching applications in high-speed testers.

Features
(1) S-VSON4: height = 1.75 mm (max), area = 1.45 mm × 2.0 mm (typ.)
(2) Normally opened (1-Form-A)
(3) OFF-state output terminal voltage: 100 V (min)
(4) Trigger LED current: 3.0 mA (max)
(5) ON-state current: 0.65 A (max)
(6) ON-state resistance: 0.6 Ω (max)
(7) Isolation voltage: 500 Vrms (min)
(8) Halogen-free
