LMBZ5246BLT1G

LRC · Zener Diodes · SOT-23

LMBZ5246BLT1G 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 Zener diode anode; the datasheet pinout is 1-Anode, 2-No Connection, 3-Cathode.
2 NC unconnected No internal connection; the datasheet labels this pin No Connection (NC).
3 Cathode passive Zener diode cathode, indicated on the package by the polarity band; the device is a Zener voltage regulator.
