Dynamic high temperaturegate bias burn-in test system(DHTGB2010)

The system performs dynamic high temperature gate bias burn-in test capabilities for the third-generation SiC MOS transistor, and each test area can independently burn up to 12 workstations. independently 12 configurable pulses, and the leakage current of the test gate does notinterfere with each other. The device is available at room temperature+10°C ~ 200°C. It has thefunction of short-circuit disengagement test of test device, which can automatically detach thefaulty device from the burn-in test without affecting the normal test of other devices.

Function
  • High-speed dv/dt>1V/ns
  • nA leakage current test
  • Threshold value voltage test
  • Customized burn-in test boards are available for different device packaging,power requirements, etc
  • Full experimenter human safety considerations are set
