FR204

LGE · Diodes - Fast Recovery Rectifiers · DO-15

FR204 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 color band on the DO-15 molded plastic case; positive-side terminal that blocks up to 400 V (VRRM/VDC for FR204) in reverse.
2 A passive Anode terminal, the end opposite the color band; carries 2.0 A average forward current at TA=55 °C with VF max 1.3 V at 2.0 A.
