The DNA of Tech™ Enables Vehicle Electrification
Vishay’s Automotive Grade Components for EV systems go beyond AEC-Q
Backed by extensive expertise in traditional automotive electronics, Vishay has developed a wide range of products to support the growing EV industry — from inductors and temperature sensors to diodes and optoelectronics. For under the hood applications, we have six decades of experience in developing components designed to withstand high temperature, high humidity conditions. To meet these conditions, Vishay has incorporated key automotive industry quality initiatives into its own Automotive Grade standard, which was developed with a goal of ZERO defects. The requirements cover design, qualification, and manufacturing, and are used to continuously improve products and processes.

48 V Resettable eFuse Reference Design
With the arrival of 48 V systems, a new method of safely connecting and disconnecting high current loads to the battery is required. This results in problems associated with arcing, which occurs when using mechanical relays. Therefore, an electronic fuse (eFuse) has been designed to switch loads up to 200 A at 48 V on a compact double-sided FR4 printed circuit board with passive cooling.
