Taiwan Semiconductor has unveiled the PUUPxxH family, a new addition to its fast recovery epitaxial diodes line. This latest series extends the benefits of FRED (fast recovery epitaxial diode) technology to applications that demand up to 6 A of operating current.
These high-reliability devices are AEC-Q101 qualified, ensuring robust performance in demanding environments. One key feature of the PUUPxxH family is its optimized switching speed versus reverse recovery time. This design characteristic enables efficient and precise switching operations, crucial for high-current applications.
Moreover, the PUUPxxH diodes offer a soft reverse recovery behavior, resulting in lower noise during switching transitions. This not only enhances the overall performance of the components but also contributes to improved system reliability.
In terms of power efficiency, the PUUPxxH series delivers low losses, helping to minimize energy wastage and maximize operational efficiency. The devices are designed to meet the growing demand for power-efficient solutions in various industries.
The TO-227 package of the PUUPxxH family features heat spreader contacts that facilitate excellent heat dissipation, ensuring optimal thermal management. This design consideration is essential for maintaining the reliability and longevity of the components, especially in high-current applications.
Furthermore, the PUUPxxH series includes models with different voltage and current ratings to cater to a wide range of application requirements. Alongside the 100 V and 200 V rated 3 A, 4 A, and 6 A models in the PUUP series, 3 A and 4 A versions are also available in SOD-128 and DO-214 packages, providing flexibility in design and implementation.
In conclusion, Taiwan Semiconductor's PUUPxxH family represents a significant advancement in fast recovery epitaxial diode technology, offering enhanced performance, efficiency, and reliability for high-current applications. By extending the benefits of FRED technology, these diodes are poised to drive innovation and excellence across various industries.
