本规范涵盖功率PNP硅2N3740和2N3741晶体管的性能要求。按照MIL“PRF”19500的规定，为每种封装的设备类型提供四个级别的产品保证（JAN、JANTX、JANTSV和JANS），为每一种未封装的设备提供两个级别的质量保证（JANHC和JANKC）。针对质量等级JANTXV、JANS、JANHC和JANKC，提供了八个辐射等级的辐射硬度保证（RHA）规定。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 power PNP silicon 2N3740 and 2N3741 transistors. Four levels of product assurance (JAN, JANTX, JANTXV, and JANS) are provided for each encapsulated device type and two levels of product assurance (JANHC and JANKC) are provided for each unencapsulated device type as specified in MIL‰ÛÒPRF‰ÛÒ19500. Provisions for radiation hardness assurance (RHA) to eight radiation levels is provided for quality levels JANTXV, JANS, JANHC, and JANKC. 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.
