MMSZ5235B_R1_00001

PANJIT International · Zener Diodes · SOD-123

MMSZ5235B_R1_00001 from PANJIT International, 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 Cathode passive Cathode terminal of the zener diode, shown as pin 1 with the label "Cathode" in the package drawing; the datasheet gives the device total power dissipation of 500 mW but no separate pin-level limit.
2 Anode passive Anode terminal of the zener diode, shown as pin 2 with the label "Anode" in the package drawing; the datasheet gives the device total power dissipation of 500 mW but no separate pin-level limit.
