**MCC Micro Commercial Components** · ESD And Surge Protection (TVS/ESD) · SOT-523

ESDU5V0T5-TP from MCC Micro Commercial Components, in a SOT-523. 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 | 1 | passive | Anode of the first protection diode (zener) in the internal structure, protected line; reverse working voltage 5 V max, clamping 11 V at IPP=1A (8/20µs). |
| 2 | 2 | passive | Anode of the second protection diode (zener) in the internal structure, protected line; reverse working voltage 5 V max, clamping 11 V at IPP=1A (8/20µs). |
| 3 | 3 | passive | Common cathode node joining both protection diodes in the internal structure; the datasheet gives no further function for this pin. |

## CAD (KiCad official)

- Symbol: `ESDU5V0T5-TP`
- Footprint: `Package_TO_SOT_SMD:SOT-523`
- 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `esdu5v0t5-tp-etched.step` / `esdu5v0t5-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esdu5v0t5-tp.step` / `esdu5v0t5-tp.glb` are the bare package body.
