1N6478-E3

Vishay Intertech · Diodes - General Purpose · DO-213AB

1N6478-E3 from Vishay Intertech, in a DO-213AB. 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 end of the single rectifier, marked by the 1st band (white, denotes device type and positive end); solderable end, up to 1.0 A average forward current and VRRM per type (1N6478 50 V to 1N6484 1000 V).
2 A passive Anode end of the single rectifier, the solderable end opposite the banded cathode; 30 A peak surge (8.3 ms half sine-wave) and VF of 1.1 V at 1.0 A.
