# H5VHT2U

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

H5VHT2U from hongjiacheng, 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 | 1 | passive | Anode of the first 5V uni-directional ESD diode in the function diagram, connected to the other diode's anode only through the common cathode pin 3. |
| 2 | 2 | passive | Anode of the second 5V uni-directional ESD diode in the function diagram, connected to the first diode's anode only through the common cathode pin 3. |
| 3 | 3 | passive | Common cathode of both ESD diodes in the function diagram, with reverse working voltage 5.0V max and ±30kV IEC 61000-4-2 air and contact ESD rating. |

## CAD (KiCad official)

- Symbol: `H5VHT2U`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `h5vht2u-etched.step` / `h5vht2u-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `h5vht2u.step` / `h5vht2u.glb` are the bare package body.
