H5VND5B from hongjiacheng, in a SOD-523. 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 | Bi-directional ESD protection terminal on the cathode-band side, protecting against IEC 61000-4-2 ±30 kV air/contact discharge with 5 V max reverse working voltage. |
| 2 | I/O2 | passive | Bi-directional ESD protection terminal opposite the cathode band, interchangeable with pin 1, rated for 8 A (8/20 µs) peak pulse current and 20 pF max junction capacitance. |
