MOC3083

Lite On · Triac, SCR Output Optoisolators · DIP-6

MOC3083 from Lite On, in a DIP-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Anode input Anode of the input infrared LED. Drive with forward current IF (recommended > IFT max = 5 mA, absolute max 50 mA) referenced to the Cathode to trigger the output triac. VF typ 1.2 V at IF = 20 mA.
2 Cathode input Cathode of the input infrared LED. Return path for the LED forward current. Reverse voltage rating VR = 6 V max.
3 NC unconnected No internal connection. Leave floating or tie to input side for creepage; do not use for signal routing.
4 MT2 passive Main Terminal 2 of the output bilateral triac. Rated VDRM = 800 V off-state, ITSM = 1 A peak repetitive surge, VTM 3 V max at 100 mA. Connects to the AC load in series with MT1.
5 Substrate unconnected Substrate connection. Not intended for external use; leave unconnected in the application circuit.
6 MT1 passive Main Terminal 1 of the output bilateral triac (paired with MT2 via internal zero-crossing circuit). Inhibit voltage VINH typ 5 V above which the device will not trigger, ensuring zero-cross switching of the AC load.
