Key parametrics for AC load isolation
The MOC3163TVM: Rated for 4170 Vrms isolation and 600 V off-state voltage, this optoisolator drives resistive or inductive AC loads up to the triac's blocking voltage. The minimum static dV/dt of 1 kV/µs ensures the output does not falsely trigger on fast voltage transients from relay coil switching or motor contactor bounce — a common failure mode in industrial panels without this rating. The built-in zero-crossing circuit turns on the triac only when the AC mains voltage crosses near zero, reducing inrush current and EMI in heater, lamp, or solenoid loads. This is the distinguishing feature versus non-zero-crossing siblings like the MOC3073M, which fire immediately on the LED trigger.
Drive requirements and temperature range
The LED requires a maximum trigger current of 5 mA to latch the triac, with a typical forward voltage of 1.3 V. The hold current is 500 µA typical — below this the triac will commutate off, so ensure the load current exceeds this threshold at the lowest operating temperature.
Package and compliance
The supplier device package is listed as 6-DIP. Approved under UL and IEC/EN/DIN standards, and fully RoHS3 compliant. The tube packaging is the standard factory format for through-hole DIPs — no tape-and-reel option is listed.
