PANJIT International · Zener Diodes · SMA(DO-214AC)
1SMA5931_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 | K | passive | Cathode, the end marked by the color band; the zener (1SMA5931, 18V nominal, 17.1 to 18.9V at 20.8mA) is reverse biased with this pin positive. |
| 2 | A | passive | Anode, the end opposite the color band; zener diode terminal that is negative in normal reverse-bias regulation. |
