DO-204

DO-204 is a family of diode semiconductor packages defined by JEDEC. This family comprises lead-mounted axial devices with round leads. Generally a diode will have a line painted near the cathode end.

Common variants

Several common packages are archived in DO-204 as variants, and may be referred to using their alternative names.

DO-7

The DO-7 is a common semiconductor package for 1N34A germanium diodes.

DO-35

The DO-35 is a semiconductor package used to encapsulate signal diodes. It is often used to package small signal, low power diodes such as 1N4148

DO-41

The DO-41 is a common semiconductor package used to encapsulate rectifier diodes. The name is derived from the JEDEC descriptor "Diode Outline, Case Style 41". DO-41 diodes are larger than signal diode packages such as DO-35, which are not required to handle large currents. The most common diode using this packaging is the 1N4001 to 1N4007 series of rectification diodes.
