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.
DO-35
The DO-35 (also known as DO-204-AH or SOD27) is a semiconductor package used to encapsulate signal diodes (i.e., diodes meant to handle small amounts of current and voltage). It is often used to package small signal, low power diodes such as 1N4148 (a 100 V, 300 mA 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 (i.e., diodes meant to handle larger currents and voltages than signal 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.
