MMSZ16T1G
onsemi · Zener Diodes · SOD-123
MMSZ16T1G 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, identified on the package by the polarity band (Style 1 pin 1 per the SOD-123 case outline). |
| 2 | Anode | passive | Anode terminal of the Zener diode (Style 1 pin 2 per the SOD-123 case outline), opposite the cathode polarity band. |
