Overview
The MIL-PRF-19500/406M specification sheet establishes performance requirements for a range of encapsulated silicon rectifiers, identified as semiconductor device types 1N4460 through 1N4496 and 1N6485 through 1N6491. Released on March 27, 2015, and superseding the prior MIL-PRF-19500/406L, this document details encapsulated, through-hole, and surface-mounted voltage regulator diodes suitable for use by the Department of Defense agencies and departments.
Scope and Ratings
The rectifiers covered by this specification offer micro-miniature 1.5 watt power capability and are designed for low leakage with voltage tolerances at 1%, 2%, and 5%. Four quality levels are provided, namely JAN, JANTX, JANTXV, and JANS, each offering different levels of product assurance. Packages include DO-41 (figure 1), and surface mount versions US (figure 2), and UM (figure 3), each with maximum storage and junction temperature ratings from -65°C to +175°C.
Product Designations and Ratings
The primary electrical characteristics span a range of nominal voltage from 3.3 V dc to 200 V dc. Variants specify voltage tolerances, with the “D” suffix indicating a 1% tolerance, “C” for a 2% tolerance, and no suffix for a 5% tolerance. There are specific maximum thermal resistance values for non-surface mount at 42°C/W and for surface mount configurations, at 20°C/W for ReJEc and 56°C/W for ReJsp. Derate figures are provided in figures 4 to 13 within the document.
Part Identification and Pin Configuration
The Part or Identifying Number (PIN) follows the guidelines of MIL-PRF-19500, detailed in sections 6.5 and 6.6. Quality level designators for encapsulated devices are presented in ascending order: JAN, JANTX, JANTXV, and JANS. The device type nomenclature starts with “1N,” followed by a second number set, which ranges from “4460” through “4496” and “6485” through “6491”. A suffix is used to indicate variants, with “C” denoting a modified version of the approved device type.
