Very Extreme temperature Testing

Example of parts characterization (I): Optical & Electrical parameters

All optical & electrical parameters of different  families  of electronic components (Electro-optical, ASIC, RF, Discrete components, passive parts, new materials, etc…) can been characterized to asses usability of parts under such environment.

Very Extreme temperature Testing Example


Example of parts characterization (II): Characterization of SiC JFET & MOSFET

Key Testing parameters:

  • Temperature characterization: SiC -> T>150ºC
  • High Voltage (up to 1700V) plus high temperature testing (175ºC)
  • High Power Tests: 17A Devices
