LMBZ5230BLT1G from LRC, in a SOT-23. 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 | Anode | passive | Anode terminal of the Zener diode; the datasheet rates the device for a junction and storage temperature range of -65 to +150 °C. |
| 2 | NC | unconnected | No connection; this pin is not internally connected on the LMBZ5230BLT1G. |
| 3 | Cathode | passive | Cathode terminal of the Zener diode, indicated by the polarity band on the package. |
