MIL-PRF-19500/124M – Semiconductor Device, Diode; Silicon, Voltage Regulator Diodes

Category: Defense Logistics Agency, Diodes, Electronics

Overview

This performance specification sheet details the requirements for a range of 10-watt, silicon voltage regulator diodes, including product assurance levels and electrical characteristics. These semiconductor devices are utilized by various Departments and Agencies within the Department of Defense and meet the standards set by the MIL-PRF-19500/124M, dated 4 December 2016, which supersedes the earlier MIL-PRF-19500/124L from 24 August 2011.

Scope Detail

The MIL-PRF-19500/124M specification outlines the performance parameters for silicon voltage regulator diodes. These devices are designed to operate at 10 watts and are available in both standard and reverse polarity forms. To cater to different requirements, four quality levels are provided: JAN, JANTX, JANTXV, and JANS. Each level denotes a product assurance standard.

Package Outline

Devices conform to the DO-4 package outline, as per the defined figures, suitable for all encapsulated types specified in this document.

Maximum Ratings and Conditions

The diodes are rated for a power dissipation (Pr) of 10 watts at a case temperature (Tc) of +55°C, with a derating factor of .083 W/°C beyond that temperature. The operating junction temperature (Tj) range is specified from -65°C to +175°C, and the storage temperature range (TstG) is from -65°C to +200°C. Maximum thermal resistance from junction to case (Rθjc) is capped at 12°C/W.

Primary Electrical Characteristics

The principal electrical characteristics of the voltage regulator diodes are defined by specific columns in the characteristics and test ratings table 3.7, which is referenced but not included in the first two pages.

Part or Identifying Number (PIN)

The specification sheet emphasizes that the Part or Identifying Number (PIN) system aligns with MIL-PRF-19500, offering examples, a list of available PINs, and supersession information within the document.

Quality Levels

For encapsulated devices, four quality level designators are applicable in accordance with this specification sheet: JAN, JANTX, JANTXV, and JANS.
