LM5Z3V9T1G from LRC, 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 of the Zener diode, with a standard Zener breakdown voltage of 3.9 V (3.7 V to 4.1 V at IZT = 5 mA). |
| 2 | ANODE | passive | Anode of the Zener diode; the device is rated for 200 mW steady state power dissipation and a forward voltage of 0.9 V max at IF = 10 mA. |
