BZT52B24

NH · Zener Diodes · SOD-123

BZT52B24 from NH, in a SOD-123. 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, marked by the white band on the package; the Zener (BZT52B24, Vz 24.0V nominal, 23.52-24.48V min-max) conducts in reverse when this pin is positive relative to the anode.
2 A passive Anode; connects to the negative side in normal reverse-Zener regulation, with maximum forward voltage 0.9V at IF=10mA.
