BZT52C3V6T from MDD（Microdiode Electronics）, 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 zener diode, identified by the marking bar on the body; BZT52C3V6T has Vz 3.6V nominal (3.4V to 3.8V) at Izt 5mA. |
| 2 | A | passive | Anode of the zener diode; the datasheet gives no pin numbers, so the numbering is inferred from the two-terminal SOD-523 package. |
