Overview of MIL-PRF-19500/406K with Amendment 2
The datasheet presents the performance specifications for micro-miniature silicon voltage regulator diodes, specifically under the MIL-PRF-19500/406K with Amendment 2, which supersedes the previous version dated November 9, 2012. This specification has received approval for use by all Departments and Agencies within the Department of Defense and outlines the requirements for procuring the described products, which adhere to MIL-PRF-19500.
Scope and Performance Requirements
The document details the standards for 1.5 watt silicon voltage regulator diodes with low leakage and varying tolerance levels of 5 percent, 2 percent, and 1 percent. It specifies physical dimensions, including DO-41, surface mount, and UM surface mount configurations (figures 1, 2, and 3, respectively) and sets forth maximum ratings for temperature and power conditions. These devices are required to operate effectively from 65°C to +175°C at various power levels and conditions, accommodating high altitude operations where reduced barometric pressure is a factor.
Primary Electrical Characteristics
Key electrical characteristics of these diodes include a direct voltage (Vz) range from 3.3 V dc to 200 V dc, with nominal voltage tolerances specified for differing device types: 1 percent for 1N4460D through 1N4496D and 1N6485D through 1N6491D, 2 percent for 1N4460C through 1N4496C and 1N6485C through 1N6491C, and 5 percent for 1N4460 through 1N4496 and 1N6485 through 1N6491.
Applicable Documents and Standards
Comprehensive references and standards necessary for compliance are listed, including the general military performance specification MIL-PRF-19500 for semiconductor devices and MIL-STD-750 for test methods. These documents are integral to this specification and available for access through the Department of Defense’s ASSIST Online database. The hierarchy/order of precedence is established, giving this document authority over referenced standards in the event of any conflicts, except where overridden by applicable laws or regulations.
