DO-41 (Diode Outline 41) component package is a very popular 2-lead through-hole package used for older diodes (incl. the famous
1N400x series). The pitch is typically 400mil, although because of the long through-hole leads, it is user variable. It is easy to solder by hand. The
DO-41 package is normally used for higher power “rectifier” diodes, whilst the lower power “signal” diodes use smaller through-hole packages such as the
DO-35. The typical rated current for a diode in this package is 1A.
Typical PCB Land Area: 22mm²
This package is normally mounted on the PCB in two ways, either flat with the legs bent at 90° to fit into the holes, or in space-constrained applications, vertical, with one of the legs straight and one bent 180° to fit into the holes in the PCB (which are closer together than when in the flat orientation. Material of package is normally moulded plastic.
