This performance specification sheet covers the requirements for 500 milliwatt, silicon, voltage regulator diodes with voltage tolerances of 5%, 2%, and 1%.


The specification includes three levels of product assurance for each encapsulated device type and two levels for each unencapsulated device.

Physical Dimensions

The diodes have physical dimensions similar to DO-35 and DO-213AA, with maximum ratings of 500 mW at +50°C and +125°C, respectively.

Primary Electrical Characteristics

The primary electrical characteristics include voltage tolerances, thermal resistance, and junction-to-end-caps thermal resistance.

Applicable Documents

The specification references other documents, including MIL-PRF-19500, MIL-STD-750, and ASME Y14.5M.


The devices must meet the requirements specified in MIL-PRF-19500 and be manufactured by an authorized manufacturer listed on the qualified manufacturer’s list (QML).
