Full Release
MALVERN, Pa., Jan. 29, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced 16 new 650 V and 1200 V
silicon carbide (SiC) Schottky diodes
in the industry-standard SOT-227 package. Designed to deliver high speed and efficiency for high frequency applications, the Vishay Semiconductors devices offer the best trade-off between capacitive charge (Q
C
) and forward voltage drop for diodes in their class.
The devices released today consist of 40 A to 240 A dual diode components in a parallel configuration, and 50 A and 90 A single phase bridge devices. Built on state of the art thin wafer technology, the diodes feature a low forward voltage drop down to 1.36 V that dramatically reduces conduction losses for increased efficiency. Further increasing efficiency, the devices offer better reverse recovery parameters than Si-based diodes and have virtually no recovery tail.
Typical applications for the components will include AC/DC PFC and DC/DC ultra high frequency output rectification in FBPS and LLC converters for photovoltaic systems, charging stations, industrial UPS, and telecom power supplies. In these applications, the diodes’ low Q
C
down to 56 nC allows for high speed switching, while their industry-standard package offers a drop-in replacement for competing solutions.
The diodes deliver high temperature operation to +175 °C and a positive temperature coefficient for easy parallelling. UL-approved to file E78996, the devices feature a large creepage distance between terminals and a simplified mechanical design for rapid assembly.
