MMSZ8V2T1G

onsemi · Zener Diodes · SOD-123

MMSZ8V2T1G 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, marked by the polarity band on the SOD-123 package; the MMSZ8V2T1G has a nominal Zener voltage of 8.2 V (range 7.79 V to 8.61 V at IZT1 = 5 mA).
2 Anode passive Anode terminal, opposite the cathode polarity band; the device is a Zener voltage regulator diode rated 500 mW on FR-4 or FR-5 board.
