MMSZ5234A_R1_00001

PANJIT International · Zener Diodes · SOD-123

MMSZ5234A_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; the datasheet polarity diagram labels pin 1 as Cathode, and the device is rated for 500 mW maximum power dissipation at TA=25°C (Note A).
2 Anode passive Anode terminal of the Zener diode; the datasheet polarity diagram labels pin 2 as Anode, and the operating junction and storage temperature range is -50 to +150 °C.
