SD15 from MDD Microdiode Semiconductor, in a SOD-323. 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 unidirectional TVS diode, connected to the protected I/O line (VRWM 15V max, breakdown VB 16.7V min at 1mA for SD15). |
| 2 | A | passive | Anode of the unidirectional TVS diode, connected to ground/return (ESD rated ±30kV air and contact per IEC 61000-4-2). |
