# MOC3063

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

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 |V(MT1-MT2)| exceeds VINH (~5 V typ, 20 V max). |
| 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. |

## CAD (KiCad official)

- Symbol: `MOC3063`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `moc3063-etched.step` / `moc3063-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `moc3063.step` / `moc3063.glb` are the bare package body.
