# TPB1000S3

**TECH PUBLIC** · Schottky Diodes · SOT-23

TPB1000S3 from TECH PUBLIC, in a SOT-23. 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 | Diode anode; the device is rated for 40 V DC blocking voltage and 1.16 A forward continuous current. |
| 2 | N.C | unconnected | No connection; pin 2 is marked N.C on the SOT-23 pin configuration. |
| 3 | CATHODE | passive | Diode cathode; reverse voltage is limited to a 40 V DC blocking voltage. |

## CAD (KiCad official)

- Symbol: `TPB1000S3`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tpb1000s3-etched.step` / `tpb1000s3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpb1000s3.step` / `tpb1000s3.glb` are the bare package body.
