LM5Z4V3T1G 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 terminal of the Zener diode; for LM5Z4V3T1G the datasheet gives VZ of 4.0 V min, 4.3 V nom and 4.6 V max at IZT = 5 mA. |
| 2 | ANODE | passive | Anode terminal of the Zener diode; the datasheet states VF = 0.9 V max at IF = 10 mA for all types. |
