Introducing Vishay's Groundbreaking Rectifiers
Vishay Intertechnology, Inc. (NYSE: VSH) has unveiled a remarkable set of rectifiers that promise to revolutionize various sectors including commercial, industrial, and automotive applications. The introduction features 27 new standard and Trench MOS Barrier Schottky (TMBS) surface-mount rectifiers packaged in the compact DFN33A layout. Notably, these devices are a significant advancement as they are the first to offer such high current ratings, making them a powerful tool for engineers and manufacturers alike.
Remarkable Design and Efficiency
The DFN33A package stands out with a compact footprint of just 3.3 mm by 3.3 mm and an ultra-slim height of 0.88 mm. This innovative design ensures efficient utilization of PCB space compared to traditional sizes. In fact, the DFN33A is 44% smaller than standard SMB packages and 20% smaller than the eSMP series, providing a perfect blend of power efficiency and space-saving design.
Unmatched Current Ratings
Vishay's new rectifiers bring several voltage options ranging from 60 V to 200 V for TMBS devices, and up to a stunning 600 V for standard rectifiers. With current ratings peaking at 6 A for standard devices and an impressive 9 A for TMBS devices, engineers can expect enhanced performance in even the most demanding applications.
Applications That Will Benefit
These rectifiers are ideal for a variety of high-frequency inverting circuits, DC/DC converters, and protection applications such as polarity and rail-to-rail guarding in hot swap designs. The devices also support power over Ethernet (PoE) solutions, ensuring robust connectivity in switches, routers, and optical network apparatus.
Superior Thermal Performance
Enhanced thermal management is achieved through Vishay's optimized copper mass design and advanced die placement technology. This enables the rectifiers to sustain higher current ratings even at elevated temperatures, withstanding operations up to +175 °C while minimizing forward voltage drop and leakage current. This level of reliability adds significant value to projects requiring consistent performance.
Enhanced Inspection and Compliance
The wettable flanks of the DFN33A package facilitate automatic optical inspection (AOI), removing the necessity for more costly X-ray inspections. In addition, these devices adhere to RoHS-compliance standards and are free from halogens, marking them as environmentally friendly components that meet stringent industry requirements.
Automated Assembly Advantage
Designed for automated assembly, these rectifiers boast an MSL moisture sensitivity level of 1 per J-STD-020 and can endure peak reflow temperatures of 260 °C. Their matte tin-plating on leads satisfies the JESD 201 class 2 whisker tests, confirming the components' reliability in a variety of environments.
Availability and More Information
The new rectifiers are available now in samples and production quantities, with a lead time of eight weeks. For those eager to learn more, Vishay maintains an extensive catalogue of discrete semiconductors and passive electronic components essential for cutting-edge innovations across a wide spectrum of markets.
