SZMMSZ5245ET1G

onsemi · Zener Diodes · SOD-123

SZMMSZ5245ET1G from onsemi, 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, marked by the polarity band on the package. The datasheet gives no further electrical limits for this pin.
2 Anode passive Anode terminal of the Zener diode, opposite the cathode polarity band. The datasheet gives no further electrical limits for this pin.
