MIL-PRF-19500/246K Silicon Power Rectifiers

The MIL-PRF-19500/246K datasheet provides detailed specifications for silicon power rectifiers, specifically types 1N3289, 1N3291, 1N3293, 1N3294, and 1N3295, as well as their reverse (R) types. These semiconductor devices are approved for use by the Department of Defense and must comply with both the datasheet and the overarching MIL-PRF-19500 specification.

Features and Requirements:

The datasheet outlines several key attributes of the silicon power rectifiers:

  • Product assurance levels as specified in MIL-PRF-19500.
  • Differentiation between normal and reverse types, based on the connection to the stud (cathode or anode).
  • Physical dimensions conforming to DO-205AA (formerly DO-8).
  • Maximum repetitive peak reverse voltage (VRSM) ranging from 240V to 1,200V.
  • Non-repetitive peak surge current (IFSM) from 200A to 1,000A.
  • Operating temperatures between -65°C and +200°C, with potential derating above 134°C.
  • Thermal resistance characteristic of 0.4°C/W.

Additional details include the devices’ barometric pressure tolerance and specific ratings for the operating junction and storage temperatures. For Tc (case temperatures) of 150°C and 134°C, different derating values are provided.

Applicable Documents and Standards:

References to government documents such as MIL-PRF-19500 (General Specification for Semiconductor Devices) and MIL-STD-750 (Test Methods for Semiconductor Devices) are included, specifying standards that these rectifiers must satisfy.

Acquisition and Compliance:

Manufacturers must be listed on the qualified manufacturer’s list (QML) before contract award to ensure adherence to the performance specifications. Compliance with the provisions of MIL-PRF-19500 is reiterated with requirements for lead finish, marking, and polarity clearly stated.

Contact information for feedback or questions is provided, directing correspondence to DLA Land and Maritime, with the suggestion to verify currency using the ASSIST Online database.

In the event of any conflict, the document text takes precedence over cited references, adhering to applicable laws and regulations without exemption.
