# CYMOC3020

**OCIC** · Triac, SCR Output Optoisolators · DIP-6

CYMOC3020 from OCIC, in a DIP-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ANODE | passive | Anode of the GaAs infrared LED input; LED trigger current IFT is 30 mA max at main terminal voltage 3V for CYMOC3020, with absolute maximum forward current 60 mA. |
| 2 | CATHODE | passive | Cathode of the GaAs infrared LED input; reverse voltage must not exceed 6 V. |
| 3 | NC | unconnected | No connection (N/C); shorted with pins 1 and 2 only for the isolation voltage test. |
| 4 | MAIN TERM. | passive | Main terminal of the photo-TRIAC output, rated for VDRM 400 V (CYMOC302X) and 100 mA RMS on-state current. |
| 5 | NC | unconnected | No connection (NC*) on the output side, marked with an asterisk in the datasheet diagram. |
| 6 | MAIN TERM. | passive | Main terminal of the photo-TRIAC output, rated for VDRM 400 V (CYMOC302X) and 100 mA RMS on-state current. |

## CAD (KiCad official)

- Symbol: `CYMOC3020`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `cymoc3020-etched.step` / `cymoc3020-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cymoc3020.step` / `cymoc3020.glb` are the bare package body.
