SZMM5Z3V0T1G from onsemi, 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 Zener regulator diode, identified by the polarity band on the package; the reverse Zener voltage VZ is referenced to this terminal with the anode at pin 2. |
| 2 | Anode | passive | Anode terminal of the Zener regulator diode, which carries forward current (VF = 0.9 V max at IF = 10 mA for all types) and is the reference for the reverse Zener voltage. |
