The requirements for acquiring the product described herein shall
consist of this specification sheet and MIL-PRF-19500.
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
encapsulated device type as specified in MIL-PRF-19500. Two level of product assurance is provided for each
unencapsulated device .
1.2 Physical dimensions. See 3.4 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 maximum and primary test ratings (see 3.9) herein and
as follows:
