本规范涵盖了NPN、硅、低功率、超高频晶体管的性能要求。为每种设备类型提供四个级别的产品保证（JAN、JANTX、JANTSV和JANS）。按照MIL-PRF-19500的规定，为未封装设备提供了两个级别的产品保证（JANHC和JANKC）。RHA等级代号“M”、“D”、“P”、“L”、“R”、“F”、“G”和“H”附加在设备前缀后，用于识别已通过RHA要求的设备。

This specification covers the performance requirements for NPN, silicon, low power, ultra-high frequency transistors. Four levels of product assurance (JAN, JANTX, JANTXV and JANS) are provided for each device type. Two levels of product assurance (JANHC and JANKC) are provided for unencapsulated devices as specified in MIL-PRF-19500. RHA level designators "M", "D", "P", "L", "R", "F", "G", and "H" are appended to the device prefix to identify devices, which have passed RHA requirements.
