LMBZ5250BLT1G

LRC · Zener Diodes · SOT-23(TO-236AB)

LMBZ5250BLT1G from LRC, in a SOT-23(TO-236AB). 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, identified as pin 1 in the datasheet pinout (1-Anode, 2-No Connection, 3-Cathode).
2 NC unconnected No internal connection; the datasheet pinout lists pin 2 as No Connection.
3 Cathode passive Cathode terminal of the Zener diode, identified as pin 3 in the datasheet pinout; the datasheet states the cathode is indicated by a polarity band on the package.
