DO-204

From Wikipedia, the free encyclopedia
Jump to: navigation, search
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 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[edit]

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

DO-35[edit]

1N4148 diodes, in the DO-35 package

The DO-35 is a semiconductor package type.[3] It is often used to package small signal, low power diodes such as 1N4148 (a 100V, 300mA silicon diode.)

DO-41[edit]

The DO-41 is a common package used to encapsulate rectifier diodes. The name is derived from the JEDEC descriptor "Diode Outline, Case Style 41".[4] 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.
