D3V3M1U2S9-7 from Diodes Incorporated, in a SOD-923. 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 | CATHODE | passive | Pin 1 is the cathode side, marked by the line on the package outline, and the device clamps ESD transients per IEC 61000-4-2 at ±30 kV contact and ±30 kV air with a 3.3 V reverse standoff voltage. |
| 2 | ANODE | passive | Pin 2 is the opposite terminal of this unidirectional TVS, with a channel input capacitance of 70 pF typical and 80 pF maximum at VR = 0 V, f = 1 MHz. |
