ESD5Z5V0 from MDD Microdiode Semiconductor, 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 unidirectional ESD protection diode, connected to the protected I/O line (VRWM 5.0V, VB min 6.2V at 1mA for ESD5Z5V0), on the banded side of the package per the circuit diagram. |
| 2 | A | passive | Anode of the unidirectional ESD protection diode, normally connected to ground, per the circuit diagram (ESD per IEC 61000-4-2 ±30kV air, ±22kV contact). |
