MMBZ5232BQ-7-F

Diodes Incorporated · Zener Diodes · SOT-23

MMBZ5232BQ-7-F from Diodes Incorporated, 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 A passive Zener anode, bottom-left terminal in the top-view device schematic; the 5.6V Zener (VZ 5.32V min to 5.88V max at IZT = 20mA) is rated for 350mW dissipation.
2 NC unconnected Bottom-right terminal, shown with no internal connection in the device schematic.
3 K passive Zener cathode, top terminal in the device schematic, which goes positive relative to the anode in reverse breakdown.
