# P3100TA

**TECH PUBLIC** · Thyristor Surge Suppressors (TSS) · SMA(DO-214AC)

P3100TA from TECH PUBLIC, in a SMA(DO-214AC). 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 | T1 | passive | Bi-directional thyristor surge suppressor terminal; the part is symmetric, with 275 V off-state voltage (VD), 350 V max switching voltage (VS) and 80 A (10/1000us) peak pulse current. |
| 2 | T2 | passive | Bi-directional thyristor surge suppressor terminal; the part is symmetric, with 120 mA typical holding current (IH) and -40 to 150 °C operating junction temperature. |

## CAD (KiCad official)

- Symbol: `P3100TA`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `p3100ta-etched.step` / `p3100ta-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `p3100ta.step` / `p3100ta.glb` are the bare package body.
