PIV 1002 - Pulsed IV-Measurement Unit

Laboratory system for the characterization of high-voltage MOSFET.

PIV1002 is a laboratory system for the characterization of high-voltage MOSFET. The system is designed to be carried out on MOSFET pulsed measurements at high voltages and currents. As a result, characteristic curves are recorded without overloading the device thermally.


For measuring an internal capacitor is charged with a high voltage SMU, which provides the necessary drain current for the pulse duration. During the pulse output, the gate-pulse voltage and the drain current become high bandwidth scanned and represented by integrated oscilloscopes. This allows a detailed analysis of the pulse shape and thermal effects on the component.

Features & Benefit

  • Maximum drain voltage: 1100 V
  • Maximum drain current: 1 A
  • Pulse Width: 250 ns - 5 ms
  • ICCAP driver
  • 2-4 Terminal devices
  • Reliability test (HCI)
  • Bulk current measurement
  • P and N-MOSFET, as well as Depletion MOSFET / 2 pin devices
  • Overcurrent protection switch (needle protection)



The measurement system can be operated via a user-friendly control software on the PC. The PIV1002 has two different operating modes:

  • Constant pulse width: The gate voltage is changed with the outer measuring loop. The measured drain-source voltage is changed with the inner loop. Hence, performance diagrams can be generated with very small pulse widths and smallest thermal loads.
  • Constant gate voltage: The pulse width is changed with the outer measuring loop. The drain voltage is changed with the inner loop. This allows for examining the thermal drift behavior of the device.
