With DOT800T, SPEA provides a complete solution for power testing, combining on a single machine all the resources to perform ISO, AC, DC test on the whole range of power applications

SPEA DOT800T Power Semiconductor Tester

Key Features


  • Market leader in mass production AC/DC test
  • One test platform for all power applications
  • Wide range of test instrumentation
  • Lowest parasitic inductance on the market
  • ISO + AC + DC Multi-station asynchronous test
  • Turnkey solution

One test platform for all power applications

DOT800T covers the complete test requirements for wafers, discretes (based on Si, SiC or GaN technology), IPMs, DBCs and IGBT modules.

Wide range of test instrumentation

The system is configurable with a complete set of instruments, providing up to 20kV voltage and 10kA current.

Lowest parasitic inductance on the market

Over-voltage is always lower than breakdown.

ISO + AC + DC Multi-Station asynchronous test

Multi-core architecture allows DOT 800 T to perform ISO test, AC test and DC test on dedicated stations, each of which with dedicated independent controller. The different test programs are performed in parallel, asynchronous way

Turnkey solution

SPEA can provide the complete solution: Tester architecture and instrumentation, contacting, software, application. Designed, manufactured, supported and guaranteed directly by SPEA.

Power Test Capabilities


  • ISO test up to 20kV
  • DC test up to 20kV / 4kA
  • AC test up to 1.5kV / 3kA
  • I Short Circuit test up to 10kA
  • UIL test
  • Built-in-digitizers on test instruments

Short Test Time


  • Multi-core multi-station architecture: parallel asynchronous ISO/DC/AC test
  • Local set-up memory for on-module set-up change
  • Embedded macros to generate ramps and triggers on V/I HV HI modules

Reliable Mixed Mode Operation


  • System wide hardware synchronization between modules
  • Embedded alarms on high voltage and high current modules (e.g. Over temp, over current, floating, Kelvin,…)

Multi-Core Architecture


DOT800T is a multi-core power tester, which can be equipped with one to three independent and configurable test cores.

Each core has an internal dedicated controller to manage the tester resources, the connection with the linked instruments, and the test program execution.
