General
The TLP3420 is a photorelay in a VSON4 that consists of a photo MOSFET optically coupled with an infrared
LED. The TLP3420 is suitable for applications that require low output capacitance and high withstand voltage,
such as LCD testers.

(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: 100 mA (max)
(5) ON-state resistance: 8 Ω (typ.), 14 Ω (max)
(6) OFF-state Capacitance: 6 pF (typ.), 8 pF (max)
(7) Isolation voltage: 500 Vrms (min)
