Insights
Vishay's introduction of 27 new rectifiers in the DFN33A package represents a meaningful expansion of their power management portfolio. The compact 3.3mm×3.3mm footprint with 0.88mm profile delivers substantial space savings—
The technical specifications are particularly notable. The TMBS variants achieve industry-leading current ratings up to 9A while standard rectifiers reach 6A, impressive for components this size. The voltage range from 60V to 600V covers diverse application requirements. This performance is enabled by Vishay's optimized copper mass design and advanced die placement technology, improving thermal characteristics while shrinking the footprint.
The wettable flanks feature is a significant manufacturing advantage, enabling automated optical inspection without X-ray requirements—reducing production costs and improving quality control for OEMs. The AEC-Q101 qualified automotive versions position these components for the growing vehicle electronics market where space constraints are increasingly challenging.
These rectifiers target critical power management functions in telecom infrastructure, industrial equipment, and automotive systems—all areas requiring compact, efficient solutions. While this release strengthens Vishay's competitive position in the discrete semiconductor space, particularly against competitors offering larger package sizes, it represents an evolutionary advancement rather than a revolutionary technology shift that would dramatically impact Vishay's financial performance.
The DFN33A package with wettable flanks addresses two critical challenges in modern electronics manufacturing: board space utilization and assembly inspection quality. With devices
From a production perspective, the wettable flanks feature is particularly valuable. This design enables automated optical inspection (AOI) of solder joints—eliminating the need for expensive X-ray inspection processes while maintaining quality assurance. This reduces manufacturing costs and inspection time while potentially improving reliability.
The package's MSL moisture sensitivity level of 1 per J-STD-020 and LF maximum peak of 260°C compatibility with standard reflow soldering processes means these components integrate seamlessly into existing manufacturing lines without special handling requirements. The RoHS-compliant and halogen-free construction aligns with global environmental regulations.
Thermal performance improvements are crucial given the industry's push toward higher power density. The optimized copper mass design allows these small components to handle substantial current loads—up to 9A in some variants—without overheating. This benefits engineers designing space-constrained applications like power over Ethernet equipment, DC/DC converters, and automotive systems where thermal management is challenging. These manufacturing advantages should strengthen Vishay's position with OEMs prioritizing board space efficiency and assembly process optimization.
Featuring Low 0.88 mm Profile and Wettable Flanks, Space-Saving Devices Provide Improved Thermal Performance and Efficiency
MALVERN, Pa., April 16, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced 27 standard and Trench MOS Barrier Schottky (TMBS®) surface-mount rectifiers in the low profile DFN33A package with wettable flanks. Providing space-saving, high efficiency solutions for commercial, industrial, telecom, and automotive applications, the standard devices are the industry’s first in this package size and provide current ratings up to 6 A, while the TMBS devices deliver industry-best current ratings up to 9 A. Offering a wide range of voltage options from 60 V to 200 V for TMBS and up to 600 V for standard rectifiers, the devices are available in Automotive Grade, AEC-Q101 qualified versions.
The latest package in Vishay’s Power DFN family, the DFN33A features a compact 3.3 mm by 3.3 mm footprint and an extremely low typical height of 0.88 mm, allowing the Vishay General Semiconductor rectifiers released today to make more efficient use of PCB space. Compared to the conventional SMB (DO-214AA) and eSMP® series SMPA (DO-220AA), the package’s size is 44 % and 20 % smaller, respectively. In addition, the device’s low profile is 2.6x thinner than the SMB (DO-214AA) and SMC, and 7 % thinner than the SMPA (DO-220AA). At the same time, the rectifiers’ optimized copper mass design and advanced die placement technology allow for superior thermal performance that enables operation at higher current ratings.
The devices are intended for low voltage, high frequency inverters, DC/DC converters, freewheeling diodes, and polarity and rail to rail protection in hot swap circuits for baseband antennas and power over Ethernet (PoE) for switches, routers, and optical network equipment. For these applications, the rectifiers offer high temperature operation up to +175 °C, while their exceptionally low forward voltage drop and low leakage current enhance design efficiency. The wettable flanks of their DFN33A package allow for automatic optical inspection (AOI), eliminating the need for an X-ray inspection.
Ideal for automated placement, the rectifiers offer an 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.
