MMSZ5248CT1G

onsemi · Zener Diodes · SOD-123

MMSZ5248CT1G 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, indicated by the polarity band; for MMSZ5248CT1G the Zener voltage is 17.64 V min to 18.36 V max (18 V nominal) at IZT = 7.0 mA.
2 Anode passive Anode terminal of the Zener diode (SOD-123 CASE 425 Style 1); forward voltage is 0.9 V max at IF = 10 mA.
