MM5Z16AWT

Shandong Jingdao Microelectronics · Zener Diodes · SOD-523

MM5Z16AWT from Shandong Jingdao Microelectronics, in a SOD-523. 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 in the PINNING table and top view of the SOD-523 outline; the datasheet states no further pin-level electrical limits.
2 Anode passive Anode terminal of the zener diode, shown as pin 2 in the PINNING table and top view of the SOD-523 outline; the datasheet states no further pin-level electrical limits.
