1N5408

Diodes Incorporated · Rectifier Diode · DO-201AD

The 1N5408 is a 3 A general-purpose rectifier rated to 1000 V reverse voltage, part of the 1N5400 glass-passivated series. Its axial DO-201AD package suits through-hole power supplies, freewheeling, and general rectification where high reverse voltage is needed.

Pinout

Pin Name Type Function
1 K passive Cathode terminal of the rectifier diode, identified by the printed band on the DO-201AD case. Blocks reverse current up to VRRM = 1000V for the 1N5408G variant.
2 A passive Anode terminal of the rectifier diode. Conventional forward current flows from anode to cathode when VF > ~0.7V (typ 1.1V at IF = 3.0A).

Key specifications
