This specification covers the performance requirements for N-channel, enhancement-mode, MOSFET, radiation hardened (total dose and single event effects (SEE)), power transistors. Two levels of product assurance are provided for each device type as specified in MIL-PRF-19500, with avalanche energy maximum rating (E_AS) and maximum avalanche current (I_AS). See 6.5 for JANHC and JANKC die versions.
