MMBZ5231BW-7-F

Diodes Incorporated · Zener Diodes · SOT-323

MMBZ5231BW-7-F from Diodes Incorporated, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the Zener diode. Under reverse bias, this terminal is held at approximately +5.1V above the anode when conducting IZT = 20mA (VZ range 4.85V-5.36V). Maximum reverse leakage 5.0µA at VR = 2.0V.
2 NC unconnected No internal connection on the second SOT-323 lead. Device schematic shows a single two-terminal Zener element; only two pads are electrically active.
3 A passive Anode of the Zener diode. Forward voltage VF = 0.9V max at IF = 10mA. Under normal Zener operation this pin is the return/ground-referenced terminal.
