DESD5Z5.0 from CBI, 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 | Cathode | passive | Cathode terminal of the ESD protection diode, identified as pin 1 in the SOD-523 top view and symbol; the datasheet gives no pin-specific electrical limits. |
| 2 | Anode | passive | Anode terminal of the ESD protection diode, identified as pin 2 in the SOD-523 top view and symbol; the datasheet gives no pin-specific electrical limits. |
