LM5Z4V7T1G 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; at IZT = 5 mA the LM5Z4V7T1G regulates at VZ = 4.4 V min, 4.7 V nom, 5.0 V max (ZZT 80 ohm max). |
| 2 | ANODE | passive | Anode of the Zener diode; forward voltage VF is 0.9 V max at IF = 10 mA, and total device dissipation is 200 mW max at TA = 25°C. |
