Circuit Protection for the Now Ubiquitous USB-C Specification

18/07/2025

In December 2024, new European Union regulations took effect that mandated USB-C charging ports for electronic devices sold in the EU. This includes all small and medium sized electronics, such as smartphones. Laptops are to follow by 2026. The law was passed years ago and so USB-C has been growing in adoption in anticipation of the law taking effect. ProTek Devices offers an integrated TVS diode array solution that safeguards USB-C devices from voltage spikes, including common surges caused by cables being improperly removed. Using transient voltage suppressors on Vbus lines and ultra-low capacitance steering diode/thyristor arrays on data lines, provides ideal results.

There are many mandatory safety systems requiring advanced electronic components in automotive applications. There is also an ever-increasing reliance on electronic technologies within the automotive sector. ProTek Devices offers surge protection solutions for a variety of automotive applications.
