600 V off-state triac output, 3750 Vrms reinforced isolation
The VOM160NT is a Vishay 1-channel triac output optocoupler rated for 600 V off-state voltage and 3750 Vrms isolation — suited for switching AC loads up to 70 mA RMS in mains-isolated circuits like solid-state relays, motor starters, and appliance controls. It is a non-zero-crossing (random-phase) device, meaning the triac fires immediately when the LED current exceeds the 5 mA max trigger threshold. This makes it a fit for phase-angle dimming or any application where turn-on timing relative to the AC waveform matters.
500 V/µs dV/dt immunity and 1.2 V forward drop
A minimum static dV/dt of 500 V/µs gives the output triac good immunity against false turn-on from fast line transients — a practical concern in motor-drive or relay-coil switching environments where inductive kickback is common. The LED forward voltage is 1.2 V typical with a maximum DC forward current of 60 mA. The 300 µA typical hold current means the triac stays latched once triggered until the load current drops below that level near the AC zero-crossing.
