MIL MIL-PRF-19500/512K涵盖了用于高速开关和驱动器应用的PNP硅晶体管的性能要求。按照MIL-UOPRF-UO19500的规定，每种封装设备类型都有四个级别的产品保证（JAN、JANTX、JANTSV和JANS），每种未封装设备类型有两个级别的质量保证（JANHC和JANKC）。辐射硬度保证（RHA）的规定，为JANTXV和JANS产品保证水平提供了八个辐射水平。RHA级别指示符“UIM-U”、“UID-U”、”UIP-UI“、”UIL-U“、”UIR-U“、“UIF-U”、、”UIG-U“和”UIH-U“被附加到设备前缀，以识别已通过RHA要求的设备。

MIL MIL-PRF-19500/512K covers the performance requirements for PNP silicon transistors for use in high speed switching and driver applications. Four levels of product assurance (JAN, JANTX, JANTXV, and JANS) are provided for each encapsulated device type as specified in MIL-UOPRF-UO19500, and two levels of product assurance (JANHC and JANKC) for each unencapsulated device type. Provisions for radiation hardness assurance (RHA), eight radiation levels is provided for JANTXV and JANS product assurance levels. RHA level designators "UIM-U", "UID-U", "UIP-UI", "UIL-U", "UIR-U", "UIF-U", "UIG-U", and "UIH-U" are appended to the device prefix to identify devices, which have passed RHA requirements.
