LGE · Zener Diodes · DO-214AC(SMA)
SZ455G from LGE, in a DO-214AC(SMA). 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 with a color band; the 5.6 V nominal Zener (VZ at IZT = 89.5 mA) is reverse-biased with this pin positive relative to the anode. |
| 2 | A | passive | Anode, the end opposite the color band; maximum forward voltage is 1.2 V at IF = 200 mA. |
