# CIQ4180

**Tokmas** · TRIACs · TO-3P

CIQ4180 from Tokmas, in a TO-3P. 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 | A1 | passive | Main terminal A1, the reference for A2 polarity and gate signals, carrying up to 40 A rms on-state current at Tc = 95 °C. |
| 2 | A2 | passive | Main terminal A2, with a non-repetitive surge peak off-state voltage of VDSM/VRSM + 100 V (tp = 10 ms, Tj = 25 °C) and 40 A rms on-state current at Tc = 95 °C. |
| 3 | G | input | Gate trigger input with IGT max 50 mA (quadrants I-II-III) or 100 mA (quadrant IV), VGT max 1.3 V and peak gate current IGM of 8 A (tp = 20 µs). |

## CAD (KiCad official)

- Symbol: `CIQ4180`
- Footprint: `Package_TO_SOT_THT:TO-3P-3_Vertical`
- 3D model: TO-3P (KiCad packages3D, STEP)
- 3D model files: `ciq4180-etched.step` / `ciq4180-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ciq4180.step` / `ciq4180.glb` are the bare package body.
