LUDZS3.0BT1G

LRC · Zener Diodes · SOD-323

LUDZS3.0BT1G from LRC, in a SOD-323. 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 K passive Cathode of the Zener diode, on the end of the package with the marking band; Zener voltage VZ is 3.01 to 3.22 V at IZT=5 mA.
2 A passive Anode of the Zener diode; the device dissipates at most 200 mW (PD) and operates from -55 to +150 °C.
