Hitachi High-Technologies GLOBAL

  1. This is an equipment that performs reliability assessment of samples by making the IGBT / IPM (Intelligent power transistor) / DIODE use the prescribed amount of electricity, and then performing intermittent energization at a predetermined time.
  2. Thermal resistance measurement can also be performed at the same time. The data is sent to the host PC.
  3. Combines IPM and DIODE testing.
