1N5408RLG

onsemi · Diodes - General Purpose · DO-201AD

1N5408RLG from onsemi, in a DO-201AD. 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, indicated by the polarity band; the 1N5408 blocks up to 1000 V (VRRM/VR) and passes 3.0 A average rectified forward current.
2 A passive Anode terminal of the rectifier diode; forward voltage is at most 1.0 V at IF = 3.0 A, TA = 25°C.
