# TPE24U2S3

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23

TPE24U2S3 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 | I/O1 | passive | TVS protected line 1 (anode of uni-directional diode to pin 3); VRWM 24V max, junction capacitance 70pF max pin 1 to pin 3. |
| 2 | I/O2 | passive | TVS protected line 2 (anode of uni-directional diode to pin 3); VRWM 24V max, junction capacitance 70pF max pin 2 to pin 3. |
| 3 | COMMON | passive | Common pin of the two TVS diodes shared by lines 1 and 2; per the p.1 diagram it is the common node, and for uni-directional use is typically the ground/return reference. |

## CAD (KiCad official)

- Symbol: `TPE24U2S3`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tpe24u2s3-etched.step` / `tpe24u2s3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpe24u2s3.step` / `tpe24u2s3.glb` are the bare package body.
