SML4746A

JUXING · Zener Diodes · DO-214AC(SMA)

SML4746A from JUXING, 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 terminal marked by the laser band; the 18 V nominal Zener (SML4746A, ±5%) is reverse-biased with this pin positive, at IZT 14 mA and ZZT 20 Ω.
2 A passive Anode, the terminal opposite the cathode band; the device dissipates at most 1.0 W with a maximum junction temperature of 150 °C.
