HESDA5V3L from HXY MOSFET, 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: one of two steering-diode channels to common pin 3, for two unidirectional lines or one bidirectional line, working voltage 5V. |
| 2 | I/O2 | passive | Protected line 2: second diode channel to common pin 3, for two unidirectional lines or one bidirectional line, working voltage 5V. |
| 3 | COMMON | passive | Common node of both diodes in the circuit diagram, the shared return (ground) for two unidirectional lines; the datasheet gives no further name. |
