AQ1003-01LTG from TECH PUBLIC, 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 | K | passive | Cathode of the 1-line uni-directional TVS diode, connected to the protected line (reverse working voltage 24V max, breakdown 26V min at 1mA). |
| 2 | A | passive | Anode of the uni-directional TVS diode, normally connected to ground; the 2-pin leadless package has only these two terminals. |
