1N5388B

LGE · Zener Diodes · DO-15

1N5388B from LGE, in a DO-15. 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 cathode band; positive terminal in zener (reverse breakdown) operation, with VZ 200 V at IZT 5.0 mA for the 1N5388B and 5.0 W maximum DC power dissipation at TL=75.
2 A passive Anode terminal, opposite the cathode band end; lead terminal of the axial DO-15 package with maximum junction temperature TJ of 150.
