4 terms

aec-q101 regulatory

"Automotive Grade T3KNxxA and T3KNxxCA series devices are AEC-Q101 qualified"

AEC-Q101 is an industry qualification standard that tests discrete semiconductor parts (like diodes and transistors) to ensure they can survive harsh automotive conditions such as heat, vibration and electrical stress. For investors, a part certified to AEC-Q101 is like a car tested for extreme road and weather conditions—it signals lower supply and reliability risk for companies that design or use those components, which can affect production, costs and product credibility.

automatic optical inspection (aoi) technical

"wettable flanks of their DFN6546A package allow for automatic optical inspection (AOI)"

Automatic optical inspection (AOI) is a machine-based visual check that uses cameras and software to scan products or circuit boards for defects, such as missing parts, incorrect placement, or surface flaws. Investors care because AOI helps companies catch quality problems early, reduce returns and rework costs, and speed up production — like a store using a fast, accurate scanner to spot damaged items before they reach customers, protecting revenue and margins.

msl moisture sensitivity level 1 technical

"the devices offer a MSL moisture sensitivity level of 1, per J-STD-020"

A moisture sensitivity level 1 part is an electronic component rated as not vulnerable to moisture-induced damage during manufacturing—it can be handled in normal factory air for an unlimited time without special drying or baking. For investors, that means lower production risk and cost because the part needs no extra humidity controls or rework, reducing potential delays and reliability concerns in the supply chain.

rohs-compliant regulatory

"The components are RoHS-compliant and halogen-free"

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

Featuring a Low 0.88 mm Profile and Wettable Flanks, Unidirectional and Bidirectional Devices Save Space and Provide Excellent Clamping Capability Up to 137 V

MALVERN, Pa., May 13, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced four series of unidirectional and bidirectional 3000 W PAR^® and TRANSZORB^® surface-mount transient voltage suppressors (TVS) in the new DFN6546A package with wettable flanks. Providing space-saving solutions for industrial and automotive applications, the Automotive Grade T3KNxxA and T3KNxxCA series devices are AEC-Q101 qualified and offer high temperature operation to +185 °C, while the 3KDFNxxA and 3KDFNxxCA series meet the LL15i Industrial Reliability Qualification.

The latest package in Vishay’s Power DFN family, the DFN6546A features a compact 6.5 mm x 4.6 mm footprint and an extremely low typical height of 0.88 mm, allowing the Vishay General Semiconductors TVS diodes released today to make more efficient use of PCB space. At the same time, the devices’ advanced construction and die placement technology allow for a higher copper content and larger chip sizes, resulting in significant performance increases. Footprint-compatible with the SMPC (TO-277A) package, the diodes offer twice the power dissipation with a 20 % lower profile. Compared to devices in the SMC (DO-214AB), they offer the same power dissipation while reducing volume by 76 %.

The TVS are designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning. Typical applications for the AEC-Q101 qualified T3KNxxA and T3KNxxCA PAR series include advanced driver assistance (ADAS), lidar, camera, infotainment, and sensor systems; DC/DC converters; battery management systems (BMS) and onboard chargers; electric power steering (EPS); traction inverters; central control units; and electrical motor drives. The industrial-qualified 3KDFNxxA and 3KDFNxxCA TRANSZORB series will be used in robot control boards, process / flow control instrumentation, automation systems, and generator start controllers; 60 kW energy storage systems; server power modules; consumer entertainment devices; and telecom and medical equipment.

For these applications, the diodes offer excellent clamping capability with maximum clamping voltages from 16.7 V to 33.2 V for the T3KNxxA and 3KDFNxxA, and 16.7 V to 137 V for the T3KNxxCA and 3KDFNxxCA. The wettable flanks of their DFN6546A package allow for automatic optical inspection (AOI), eliminating the need for an X-ray inspection. Ideal for automated placement, the devices offer a MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260 °C. The components are RoHS-compliant and halogen-free, and their matte tin-plated leads meet the JESD 201 Class 2 whisker test.
