The continued growth of electrification of vehicles has driven the need for communication ICs with thousands of volts of isolation. Production level partial discharge testing allows manufacturers to ensure and specify the isolation level as well as the leakage through the isolation barrier. It goes without saying that devices with high isolation and lower inherent charge (pC) have an increased value in the market. To accurately and repeatably test these devices, one needs a solution that can stress these devices to the industry specification and accurately measure the inherent charge. In this TUG paper, we will quickly cover the market and why these devices are required, with focus on electrification of vehicles. At a high level, what systems in a vehicle require this technology and why. Then we will deep dive into the specifications of partial discharge and the current industry standard and the challenges that it created for mass production testing with thousands of volts of specified and guaranteed isolation. We will also cover what values semiconductor manufacturers can benefit from with robust, accurate, and repeatable production test solutions. Finally, wrap up with the latest Teradyne solution and the benefits it can provide to the industry.
