MOC3063 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	LED anode. Forward-bias the input LED (VF ~1.2 V typ at IF=20 mA) with IF >= IFT (5 mA max for MOC3063) to trigger the output triac. Absolute max IF = 50 mA.
2	Cathode	input	LED cathode. Return for the input LED drive current. Reverse voltage rating VR = 6 V.
3	NC	unconnected	No internal connection. Leave floating or tie as convenient for PCB routing.
4	MT2	passive	Main terminal 2 of the output triac. Switches AC load current (ID(RMS) = 100 mA, ITSM = 1 A) up to VDRM = 600 V off-state. Zero-cross circuit inhibits triggering when
5	Substrate	unconnected	Substrate connection. Do not connect externally (leave floating).
6	MT1	passive	Main terminal 1 of the output triac. Companion terminal to MT2 for switching the AC load. On-state peak voltage VTM = 3.0 V max at ITM = 100 mA peak; holding current IH ~400 uA typ.
