3SMB5935B

LGE · Zener Diodes · SMB

3SMB5935B from LGE, in a SMB. 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 end marked by the color band; the Zener voltage is 27 V nominal at IZT = 13.9 mA for the 3SMB5935B.
2	A	passive	Anode, the end opposite the color band; the maximum forward voltage is 1.5 V at IF = 200 mA.
