**Yangzhou Yangjie Elec Tech** · IC · SOT-23

ESD2402EB from Yangzhou Yangjie Elec Tech, 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 bi-directional TVS to pin 3, with reverse stand-off voltage ±24V max and ±30kV IEC61000-4-2 contact/air ESD rating. |
| 2 | I/O2 | passive | Protected line 2 bi-directional TVS to pin 3, with reverse stand-off voltage ±24V max and ±30kV IEC61000-4-2 contact/air ESD rating. |
| 3 | COM | passive | Common pin shared by both bi-directional TVS diodes (pin 1 and pin 2 each clamp against pin 3); datasheet gives no ground/supply designation. |

## CAD (KiCad official)

- Symbol: `ESD2402EB`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `esd2402eb-etched.step` / `esd2402eb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd2402eb.step` / `esd2402eb.glb` are the bare package body.
