H3V3LD5B 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 | A1 | passive | Bi-directional ESD protection terminal (cathode-band side of the SOD-523 body) with 3.3V max reverse working voltage, interchangeable with the other terminal and connected to the protected line. |
| 2 | A2 | passive | Bi-directional ESD protection terminal (opposite end from the cathode band) with 3.3V max reverse working voltage, connected to ground or the second line being protected. |
