LM5Z9V1T1G 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 (pin 1) of the Zener diode; for LM5Z9V1T1G the Zener voltage is 8.5 V min, 9.1 V nom, 9.6 V max at IZT = 5 mA. |
| 2 | ANODE | passive | Anode terminal (pin 2) of the Zener diode; total device dissipation is rated 200 mW at TA = 25°C on an FR-5 board. |
