DO-204

General form of the packages described by DO-204. Lead diameter is not controlled less than E from the body to allow for minor irregularities.

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 (also known as DO-204-AA) is a common semiconductor package for 1N34A germanium diodes.[3][12]

DO-35

The DO-35 (also known as DO-204-AH or SOD27) is a semiconductor package used to encapsulate signal diodes.[10][13][2] It is often used to package small signal, low power diodes such as 1N4148 (a 100V, 300mA silicon diode.)

DO-41

The DO-41 (also known as DO-204-AL or SOD66) is a common semiconductor package used to encapsulate rectifier diodes.[11][14] The name is derived from the JEDEC descriptor "Diode Outline, Case Style 41".[2] 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 1N400x series of rectification diodes.
