1SMA5933B

LGE · Zener Diodes · DO-214AC(SMA)

1SMA5933B 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, marked by the color band on the SMA (DO-214AC) package; positive terminal in zener (reverse breakdown) operation, 1SMA5933B has a nominal 22 V zener voltage at 17.0 mA test current.
2 A passive Anode, the end opposite the color band on the SMA (DO-214AC) package; maximum forward voltage is 1.5 V at IF = 200 mA.
