PANJIT International · Zener Diodes · SMA(DO-214AC)
1SMA4746_R1_00001 from PANJIT International, in a SMA(DO-214AC). 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 | The color band denotes the cathode end, so pin 1 is the cathode of this two-terminal Zener diode. |
| 2 | Anode | passive | Pin 2 is the anode, the terminal opposite the color-banded cathode; the datasheet states no further electrical limit for this pin. |
