LMBZ5245BLT1G 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 of the Zener diode; the pinout is given as 1-Anode, 2-No Connection, 3-Cathode for this series, and LMBZ5245BLT1G is specified at nominal VZ 15 V (14.25 V min to 15.75 V max) at IZT 8.5 mA. |
| 2 | NC | unconnected | No connection; the datasheet pinout lists this pin as No Connection (NC). |
| 3 | Cathode | passive | Cathode of the Zener diode, indicated by the polarity band on the package; the device is rated 225 mW total power dissipation on FR-5 board at TA = 25°C. |
