Vishay reveals technology slate for electronica

"At electronica, one of our primary goals is to show engineers that we are a one-stop shop with a very broad portfolio of solutions to meet all of their application needs," said Johan Vandoorn, Chief Technical Officer and Deputy to the CEO at Vishay. "We will be exhibiting an enormous range of products in both our main and automotive booths. Highlighted new products such as our gallium nitrite MOSFETs, multi-spectral optical sensors, and diodes for 48V electrical and hybrid vehicles will demonstrate that we are innovative across a variety of market segments, from automotive and IoT to home automation and 5G."

Vishay will highlight its capability to deliver a custom passive solution to meet specific design requirements. Experts will be on hand to talk about the variety of core materials and terminations available for filter inductors and power pulse transformers; enclosure types for grid resistors; shapes and sizes for RF power plate capacitors; pre-conditioning options for wirewound resistors; and much more.

Another feature will be the automotive X-Ray demonstration which enables an X-ray view inside an e-Car to see how Vishay technology is enabling the e-mobility evolution.

MOSFETs on display boasting the latest GaN technology will include a 100V enhancement-mode GaN HEMT device with a dedicated Kelvin source gate return.

With a gate charge of only 5nC — more than 10x lower than existing silicon MOSFET technology — and on-resistance of 5mΩ, the device offers low gate charge times on-resistance FOM to reduce switching losses.

For DC/DC conversion and battery management, Vishay will be showcasing power MOSFETs in new space-saving PowerPAK 8x8L packages; XCLAMPR transient voltage suppressors (TVS) with extremely low clamping ratios; custom magnetics including hybrid planar transformers; battery shunt resistors; DC-Link film capacitors; IHLP low profile, high current inductors; current limiters featuring PTC resistors; and high current thermal fuses.

A fully integrated, light to digital sensor for proximity sensing up to 1.5meters with 12- or 16-bit resolution will be on show, in addition to a capacitive atmospheric humidity sensor with a humidity range of 10% to 90%.

For IoT power management, transmitter burst current support, and replacement of high capacitance MLCCs, Vishay will parade vPolyTan polymer surface-mount chip capacitors designed to deliver increased volumetric efficiency.

Combining polymer tantalum technology with Vishay's high efficiency MicroTan packaging, the devices achieve industry-best capacitance-voltage ratings in six molded case codes.Vishay will highlight surface-mount, high-frequency MLCCs with Q > 2000 andultra low ESR; high temperature MLCCs offering an excellent aging rate of 0 % per decade; and surface-mount RF capacitors with low DCR and high Q.
