Insights
The introduction of Vishay Intertechnology's new series of transient voltage suppressors (TVS) represents a significant evolution in the design and application of protective components in various electronic systems. The compact footprint and low profile of these devices are important for modern electronics, where space is at a premium. The ability to operate at high temperatures up to +185 °C also indicates robustness, which is particularly important in harsh environments like automotive or industrial settings.
From an engineering perspective, the wettable flanks feature is a noteworthy advancement. It facilitates automatic optical inspection (AOI), which is a cost-effective method for quality control during manufacturing. This eliminates the need for X-ray inspection, reducing production costs and time. Moreover, the moisture sensitivity level of 1 indicates that these devices can withstand higher levels of humidity, which enhances their reliability in various applications.
Furthermore, the adherence to RoHS compliance and being halogen-free reflects the industry's ongoing commitment to environmental sustainability. The compliance with the JESD 201 class 2 whisker test is also significant as it addresses concerns related to tin whisker growth, which can cause short circuits in electronic components.
The release of new TVS devices by Vishay Intertechnology is strategically positioned to meet the increasing demand for more efficient use of PCB space in high-growth sectors such as automotive ADAS, battery management systems and infotainment. These sectors are experiencing rapid innovation, with a consistent push towards miniaturization and higher performance standards.
The market for electronic components in the automotive sector, especially, is expected to grow significantly as the industry moves towards electric and autonomous vehicles. The AEC-Q101 qualification of the automotive-grade TVS suggests that Vishay is targeting this lucrative segment and is well-aligned with industry quality standards.
However, the lead time of 12 weeks could be a potential drawback in an industry where speed to market is critical. It will be important for Vishay to manage its supply chain effectively to meet the expected demand and minimize potential disruptions that could arise from such lead times.
Vishay Intertechnology's launch of the new TVS series could have a positive impact on their financial performance, given the broad application range of these components. The adoption of these TVS devices across various sectors could lead to an increase in sales volume, potentially improving the company's revenue. Moreover, the operational efficiencies gained from the AOI-compatible wettable flanks could lead to margin improvements over time.
Investors should monitor the adoption rate of these new components, as it will be a key indicator of Vishay's competitive positioning in the semiconductor market. It's also important to consider the company's ability to scale production and maintain quality, as any issues here could affect the brand's reputation and financial outcomes.
In the context of the broader market, Vishay's innovation in component design and commitment to sustainability may enhance its appeal to environmentally conscious investors, possibly influencing its stock performance positively.
Featuring Compact 3.8 mm by 2.0 mm Footprint, Low 0.88 mm Profile, and Wettable Flanks, Space-Saving Devices Offer Operating Temperatures to +185 °C
MALVERN, Pa., April 10, 2024 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced four new series of surface-mount industrial-grade TRANSZORB® and Automotive Grade PAR® transient voltage suppressors (TVS) in the low profile DFN3820A package with wettable flanks. Providing space-saving solutions for automotive, computer, consumer, and industrial applications, the 6DFNxxA, 6DFNxxxCA, T6NxxA, and T6NxxxCA offer peak pulse power of 600 W at 10/1000 μs and low leakage current down to 1 μA.
The first package in Vishay’s new Power DFN family, the DFN3820A features a compact 3.8 mm by 2.0 mm footprint and an extremely low typical height of 0.88 mm, allowing the Vishay General Semiconductor TVS to make more efficient use of PCB space. Footprint-compatible with the SMP (DO-220AA) package, the DFN3820A is 85 % smaller than the SMB (DO-214AA) and 42 % smaller than the SlimSMAW (DO-221AD), but it keeps peak pulse power dissipation with a 10/1000 μs waveform at 600 W.
The devices released today are designed to protect sensitive electronic equipment against voltage transients induced by inductive load switching and lightning. The 6DFNxxA and 6DFNxxxCA TRANSZORB TVS will be used for signal line protection in server power modules, digital media controllers, and AV signal extenders for computer and consumer applications, in addition to industrial robot control boards, process / flow control instruments, and automation systems.
AEC-Q101 qualified and offering high temperature operation to +185 °C, the T6NxxA and T6NxxxCA PAR TVS are intended for automotive load dump protection. Typical applications will include advanced driver assistance (ADAS), battery management (BMS), electric power steering (EPS), and infotainment systems; central control units; on-board chargers (OBC); DC/DC converters and traction inverters; and electrical motor drives.
The TVS offer excellent clamping capability with a maximum clamping voltage from 16.7 V to 70.1 V for the 6DFNxxA and T6NxxA, and 16.7 V to 137 V for the 6DFNxxxCA and T6NxxxCA. The wettable flanks of their DFN3820A package allow for automatic optical inspection (AOI), eliminating the need for an X-ray inspection. Ideal for automated placement, the rectifiers offer a MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260 °C. The devices are RoHS-compliant and halogen-free, and their matte tin-plated leads meet the JESD 201 class 2 whisker test.
