Vishay Introduces Compact, High-Power TVS Devices for Automotive and Industrial Applications

Vishay Intertechnology

MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH), a leading global manufacturer of discrete semiconductors and passive electronic components, has launched four new series of transient voltage suppressors (TVS) designed to enhance protection and efficiency in automotive and industrial electronics. These new surface-mount devices, featuring the compact DFN3820A package with wettable flanks, mark a significant evolution in Vishay’s product offerings, catering to the growing demand for space-saving solutions in various applications.

The newly unveiled 6DFNxxA, 6DFNxxxCA, T6NxxA, and T6NxxxCA series boast a peak pulse power of 600 W at 10/1000 μs and exhibit low leakage current, down to 1 μA. Their introduction positions Vishay at the forefront of innovations aimed at safeguarding sensitive electronic equipment against voltage transients induced by phenomena such as inductive load switching and lightning strikes.

These devices are housed in the DFN3820A package, Vishay’s first entry into its new Power DFN family. This package provides a significant reduction in footprint and height, offering an 85% size decrease compared to the SMB (DO-214AA) package and a 42% reduction over the SlimSMAW (DO-221AD). Such compactness allows for more efficient utilization of printed circuit board (PCB) space without compromising on power dissipation capabilities.

The TRANSZORB TVS devices, specifically the 6DFNxxA and 6DFNxxxCA series, are tailored for signal line protection across a wide range of applications, from server power modules and digital media controllers in computer and consumer sectors to industrial robot control boards and automation systems. On the other hand, the T6NxxA and T6NxxxCA PAR TVS series, which are AEC-Q101 qualified and support high temperature operations up to +185 °C, are designed primarily for automotive applications including advanced driver assistance systems (ADAS), battery management systems (BMS), and infotainment systems, providing robust load dump protection.

An additional feature of these TVS devices is their excellent clamping capability, with maximum clamping voltages ranging from 16.7 V to 137 V across the series. The inclusion of wettable flanks facilitates automatic optical inspection (AOI) processes, thereby eliminating the need for X-ray inspections—a boon for manufacturers aiming to streamline production and ensure quality control.

Moreover, these devices are RoHS-compliant and halogen-free, with matte tin-plated leads that meet the stringent JESD 201 class 2 whisker test, further underscoring Vishay’s commitment to environmental sustainability and reliability.

The launch of these TVS devices by Vishay Intertechnology not only enhances the company’s portfolio but also reflects the broader industry trend towards miniaturization and increased efficiency in electronic component design. As electronic systems in automotive and industrial applications become more complex and integrated, the need for compact, high-performance protection components like these TVS devices becomes ever more critical. Vishay’s latest offerings are set to play a pivotal role in meeting these demands, ensuring the continued growth and technological advancement of these sectors.
