**TECH PUBLIC** · ESD Protection Devices · SOT-23

TPE24MCANS3 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 | Protected line 1 of the 2-line bi-directional TVS, with reverse working voltage 24 V max and breakdown 25.7 V min at 1 mA. |
| 2 | I/O2 | passive | Protected line 2 of the 2-line bi-directional TVS, with reverse working voltage 24 V max and breakdown 25.7 V min at 1 mA. |
| 3 | COMMON | passive | Common node of the diode pair, shown on the pin configuration as the shared connection of both TVS steering paths, with 30 pF typ junction capacitance to pin 2 or pin 1 and 55 pF max. |

## CAD (KiCad official)

- Symbol: `TPE24MCANS3`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tpe24mcans3-etched.step` / `tpe24mcans3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpe24mcans3.step` / `tpe24mcans3.glb` are the bare package body.
