S-LM3Z7V5T1G from LRC, in a SOD-323. 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 of the Zener diode, indicated by the polarity band on the SOD-323 package; the Zener voltage of the LM3Z7V5 is 7.5 V nominal (7.0 V to 7.9 V) at IZT = 5 mA. |
| 2 | ANODE | passive | Anode of the Zener diode on the SOD-323 package; the device is rated for 200 mW power dissipation and a junction/storage range of -65 to +150 °C. |
