MMSZ5230B-TP from MCC Micro Commercial Components, in a SOD-123. 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, the end marked with the cathode band; it goes positive of the anode in zener breakdown (VZ 4.7V nominal, ±5%, at IZT=20mA for MMSZ5230B). |
| 2 | A | passive | Anode, the end opposite the cathode mark; forward voltage is at most 0.9V at IF=10mA. |
