2EZ39D5

SUNMATE Elec · Zener Diodes · DO-41

2EZ39D5 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	CATHODE	passive	Cathode is the lead at the end marked by the color band, and the datasheet rates the part at 2.0 W DC power dissipation at TL = 75 °C with lead length 3/8 in (9.5 mm) from body.
2	A	passive	Anode is the lead at the end opposite the color band, with a maximum forward voltage of 1.2 V at IF = 200 mA and a junction temperature range of -55 to +175 °C.
