Teradyne, Inc., a global leader in automated test equipment and advanced robotics, has announced the release of the ETS-800 D20, the newest member of the ETS-800 platform. The system is designed to meet growing demand for precise, scalable, and cost-effective testing solutions in power semiconductors, serving industries that depend on high performance, reliability, and efficiency.
The ETS-800 D20 brings a dual sector test head system to market, providing a flexible and efficient platform for all test insertions and package types. This design allows configuration for low-volume testing with up to two instruments or high-volume production with up to eight parallel test sites, enabling manufacturers to optimize for both throughput and versatility.
“We are thrilled to introduce the Teradyne ETS-800 D20. This new system offers a cost-effective and flexible solution for high volume and high mix/low volume device testing for the power semiconductors enabling today’s most critical systems and applications,” said Dominic Viens, Vice President and General Manager of the Power Test division at Teradyne. “With its advanced features and compatibility with existing instruments and systems, the ETS-800 D20 is poised to meet the evolving needs of our customers to help them achieve their production goals.”
Addressing Modern Testing Demands
As artificial intelligence (AI) continues to transform cloud computing infrastructure, the need for accurate and stable power supplies has become critical. Power devices must deliver clean voltage outputs and precise measurements, especially for ultra-low resistance components that influence system reliability.
The ETS-800 platform supports these demands by providing rapid current delivery and simultaneous ultra-low resistance measurement—minimizing heat generation and power loss. The platform’s scalability ensures a smooth transition from prototype to high-volume production, aligning with the evolving needs of AI servers, electric vehicles (EVs), and battery management systems (BMS).
Technical Highlights
The ETS-800 D20 brings together several key capabilities that make it a standout in the field of semiconductor testing and non-destructive electrical validation:
- Flexible Testing Configuration: Supports high-volume or high-mix/low-volume applications for power semiconductors.
- Extensible Platform: Shared tests, instruments, docking, and software across ETS-800 systems maximize capital efficiency.
- High Performance: Delivers higher channel density, faster test cycles, and increased parallelism.
- Widest Dynamic Range: Expands test coverage for precision power and analog devices.
Driving Reliability and Energy Efficiency
As EV adoption accelerates and data centers demand greater energy efficiency, power semiconductors play a critical role in reducing energy losses, heat generation, and operational costs. The ETS-800 D20 ensures manufacturers can achieve the accuracy, speed, and repeatability needed for these high-stakes applications.
By enabling high channel density and parallel testing, the new system helps companies shorten validation cycles, improve yield, and accelerate time-to-revenue—all while maintaining the highest standards of reliability and measurement integrity.
