Kelvin Contactor for High Power Applications Proves Performance

The ecoAmp™ specifically responds to the challenging requirements of high voltage/high current test. All typical packages and modules for power applications are covered by the ecoAmp™, including MOSFETs, drivers, IGBTs, power modules, and power packages such as TO, SO and DIP.

In order to achieve equal current symmetry over I/Os within the contactor, the contacting resistance is held low and stable. Resistance stability is influenced by the contact spring itself AND the condition of the device pin. The ecoAmp™ is designed for an electrical performance of 500+ amperes with an inductance of 1.0 nH and below for 0.5 mm pitch.

The high power contactor allows for testing at the full temperature range from -60°up to 175°C, which is a standard requirement for automotive applications. The ecoAmp™ is able to stand the high thermal stress and support temperature stability during test. Thermal energy dissipation requires thermal management within the contactor.

Gerhard Gschwendtberger, Business Unit Manager (Contactors) comments: “We received very positive feedback from this customer about the results of the evaluation in the HVM environment. The ecoAmp™ leverages our long-term experience in the automotive market for the new requirements of high power applications for automotive as well as energy efficiency, energy harvesting and green energy applications.”
