MMSZ5236BT1G from onsemi, 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 | Cathode | passive | Cathode terminal, identified by the polarity band on the SOD-123 package, per the datasheet's Style 1 pin assignment. |
| 2 | Anode | passive | Anode terminal, per the datasheet's Style 1 pin assignment for the SOD-123 package (the datasheet gives no separate pin-level limit for this terminal). |
