2EZ47D5

SUNMATE Elec · Zener Diodes · DO-41

2EZ47D5 from SUNMATE Elec, in a DO-41. 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, end marked with the color band; the Zener (2EZ47D5, VZ 47 V at IZT 10.6 mA) is reverse-biased with this terminal positive.
2 A passive Anode, axial lead at the end opposite the color band.
