# MOC3023

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

MOC3023 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. Forward current IF max 50 mA, VR max 6 V, PD 70 mW. Drive with a current-limited source; IFT (max trigger current) is 15 mA for MOC3023. |
| 2 | Cathode | input | Cathode of the input infrared LED. Return path for the LED forward current. |
| 3 | NC | unconnected | No internal connection. Leave floating on the PCB. |
| 4 | MT1 | passive | Main Terminal 1 of the output bilateral silicon switch (triac driver). Rated Vdrm 400 V min, peak repetitive surge current ITSM 1 A (PW=100us, 120 pps), collector power dissipation 300 mW. Connects to the AC-line / gate-drive network of the power triac. |
| 5 | SUB | unconnected | Substrate. Do not connect; treat as NC. |
| 6 | MT2 | passive | Main Terminal 2 of the output bilateral silicon switch (triac driver). Rated Vdrm 400 V min, peak repetitive surge current ITSM 1 A. Together with pin 4 forms the AC-switched output that controls the gate of a larger power triac. |

## CAD (KiCad official)

- Symbol: `MOC3023`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `moc3023-etched.step` / `moc3023-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `moc3023.step` / `moc3023.glb` are the bare package body.
