# TPMEG4002ESFYL

**TECH PUBLIC** · Schottky Diodes · 0201

TPMEG4002ESFYL from TECH PUBLIC, in a 0201. 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 | CATHODE | passive | Cathode of the Schottky barrier diode; reverse voltage rating 40 V, forward current 200 mA DC. |
| 2 | ANODE | passive | Anode of the Schottky barrier diode; forward voltage max 0.39 V at IF=10 mA and 0.61 V at IF=200 mA. |

## CAD (KiCad official)

- Symbol: `TPMEG4002ESFYL`
- Footprint: `Diode_SMD:D_0201_0603Metric`
- 3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal _01005_ 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: `tpmeg4002esfyl-etched.step` / `tpmeg4002esfyl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpmeg4002esfyl.step` / `tpmeg4002esfyl.glb` are the bare package body.
