1N5404RLG

onsemi · Diodes - General Purpose · DO-201AD

1N5404RLG 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 CATHODE passive Cathode terminal, marked by the polarity band on the body; the 1N5404 is rated 400 V peak repetitive reverse voltage (VRRM) and 3.0 A average rectified forward current at TL = 105°C.
2 ANODE passive Anode terminal; forward current flows from anode to cathode, with a non-repetitive peak surge current of 200 A (one cycle, 8 ms half-sine) and a junction/storage temperature range of −65 to +175°C (Tstg) and −65 to +150°C (TJ).
