MAXIMUM JUNCTION AND STORAGE TEMPERATURE 150oC MAXIMUM OPERATING TEMPERATURE 125oC
MIL-PRF-38535
SLIDE 5
DEFINITION OF HIGH TEMPERATURE ELECTRONICS?
◆ NO INDUSTRY STANDARDS OR AGREEMENT ◆ “ELECTRONICS OPERATING AT TEMPERATURES IN
EXCESS OF THOSE NORMALLY ENCONTERED BY CONVENTIONAL SILICON-BASED SEMICONDUCTORS OR THEIR AUXILLARY COMPONENTS.”1
◆ TYPICALLY >125oC OR >150oC BUT SOME REPORTED
LAB WORK TO 600oC.
