VISHAY UF540 Series Fast Ultrafast Diode, 3 A, Single, 1.7 V, 75 ns, 150 A - 800
VISHAY UF540 fast diode: 800V, 3A, 75ns recovery. Ideal for power supplies, inverters & switching circuits. DO-201AD package.
The VISHAY UF540 Series is a range of high-performance fast and ultrafast rectifier diodes, engineered for demanding electronic applications requiring rapid switching and efficient rectification. These robust diodes are designed to deliver reliable operation in power supplies, inverters, and switching circuits where speed and voltage handling are critical.
Featuring a low forward voltage drop of just 1.7V and an exceptionally fast reverse recovery time of 75ns, these components minimise power losses and enhance overall circuit efficiency. The diodes are housed in a sturdy DO-201AD package, offering excellent thermal characteristics and mechanical durability for through-hole mounting on printed circuit boards.
With a high repetitive peak reverse voltage of 800V and an average forward current rating of 3A, this series is capable of handling significant power levels. A substantial forward surge current rating of 150A provides excellent protection against inrush currents, ensuring longevity and reliability in challenging environments. The maximum operating temperature of 150°C allows for use in a wide range of industrial and commercial settings.
Ideal for engineers and technicians, the VISHAY UF540 diodes are a trusted choice for constructing efficient and compact power conversion systems. Their consistent performance and quality construction make them a staple component in modern electronic design, from consumer electronics to industrial machinery.
