MM5Z2V4T1G 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 (polarity band) of the Zener diode; the MM5Z2V4T1G has a nominal Zener voltage of 2.4 V (2.2 V min to 2.6 V max) at the test current. |
| 2 | Anode | passive | Anode of the Zener diode; forward voltage is 0.9 V max at IF = 10 mA. |
