2EZ7.5D5

EIC Semicon · Zener Diodes · DO-41

2EZ7.5D5 from EIC Semicon, 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, marked by the color band on the DO-41 axial package; the zener (VZ 7.5 V at IZT 66.5 mA) is reverse-biased with this lead positive.
2 A passive Anode, the axial lead at the end opposite the color band of the DO-41 package; maximum forward voltage is 1.2 V at IF = 200 mA.
