1. SCOPE
1.1 Scope. This specification covers the performance requirements for 500 milliwatt, silicon, voltage regulator diodes with voltage
tolerances of 5, 2, and 1 percent. Three levels of product assurance are provided for each device type as specified in MIL-PRF-19500.
Two level of product assurance is provided for die.
1.2 Physical dimensions. See 3.3 and figure 1 (similar to DO-35) and figure 2 (similar to DO-213AA), and figures 3 and 4 for die.
1.3 Maximum ratings. Maximum ratings are as shown in column 4 table II herein and as follows:
