    These devices are as thin as 0.88mm and feature side pads that are easy to absorb solder, saving space while offering higher thermal performance and efficiency
    MALVERN, Pennsylvania, USA; Shanghai, China - April 24, 2025 - Vishay Intertechnology, Inc. (NYSE: VSH) recently announced the launch of 27 standard and grooved MOS barrier Schottky (TMBS?) Surface mount rectifier in DFN33A package, which is thin and has side pads that are easy to adsorb solder. These standard devices are the industry's first to adopt this package size, providing space-saving and efficient solutions for commercial, industrial, communication and automotive applications. They have A rated current of up to 6 A, while TMBS devices achieve an industry-leading rated current of up to 9 A. TMBS? The device offers multiple voltage options ranging from 60 V to 200 V, and the maximum voltage of the standard rectifier can reach up to 600 V. These devices all have automotive-grade versions and comply with the EC-Q101 certification.

    DFN33A is the latest package size of the Vishay Power DFN series, featuring a compact size of 3.3mm x 3.3mm and a typical thickness as low as 0.88mm. Therefore, The Vishay General Semiconductor rectifier released recently can make more efficient use of PCB space. Compared with traditional SMB (DO-214AA) and eSMP? Compared with the series SMPA (DO-220AA), the package sizes are reduced by 44% and 20% respectively. Furthermore, the device thickness is 2.6 times thinner than that of SMB (DO-214AA) and SMC, and 7% thinner than that of SMPA (DO-220AA). Meanwhile, the optimized copper design of the rectifier and advanced chip mounting technology ensure excellent heat dissipation performance, allowing it to operate at higher rated currents.

    These devices are applicable to polarity protection and rail-to-rail protection in low-voltage, high-frequency inverters, DC/DC converters, freewheeling diodes, baseband antenna hot-swicking circuits, as well as Power over Ethernet (PoE) for switches, routers and optical network equipment. For these applications, rectifiers can be used up to +175? It operates at high temperatures. Meanwhile, the device's extremely low forward voltage drop and low leakage current enhance the design efficiency. The DFN33A package features side pads that are easy to attach solder, allowing for automatic optical inspection (AOI) without the need for X-ray inspection.
    These rectifiers are highly suitable for automatic mounting. According to the J-STD-020 standard, their humidity sensitivity (MSL) is grade 1, and the maximum reflux peak temperature reaches 260? C. These devices comply with RoHS regulations, are halogen-free, and their matte tin-plated pins meet the requirements of JESD 201 Type II whiskers test.
Device Specification sheet:

    Note: The suffix of the basic part number for industrial-grade products is -M3, and the suffix of the basic part number for automotive-grade products that comply with the EC-Q101 standard is -HM3
    Samples of the brand-new standard and TMBS rectifiers in DFN33A packaging are now available and mass production has been achieved, with an order cycle of 8 weeks.
