This specification covers the performance requirements for silicon, voltage regulator diodes with
voltage tolerances of 5 percent, 2 percent, and 1 percent. Four levels of product assurance (JAN, JANTX, JANTXV, and JANS) are provided for each encapsulated device type as specified in MIL-PRF-19500, and two levels of product assurance (JANHC and JANKC) for each unencapsulated device type die.
