RM3A

EIC Semicon · Diodes - General Purpose · DO-201AD

RM3A from EIC Semicon, 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, the axial lead at the color-band end of the DO-201AD body (lead length 1.00 in (25.4 mm) min).
2 A passive Anode, the axial lead at the end opposite the color band (lead length 1.00 in (25.4 mm) min), rated 2.5 A average forward current.
