LMBZ5245BLT1G

LRC · Zener Diodes · SOT-23

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.
