regulator diodes with voltage tolerances of 5 percent, 2 percent, and 1 percent. Three levels of product assurance
are provided for each encapsulated device type as specified in MIL-PRF-19500, and two levels of product assurance
for each unencapsulated device type die. For JANHC and JANKC quality levels (see 6.5).
