In the industry-standard SOT-227 packaging, Vishay Intertechnology unveiled 16 new silicon carbide (SiC) Schottky diodes operating at 650 V and 1200 V.
The Vishay Semiconductors devices provide the best trade-off between capacitive charge (QC) and forward voltage loss for diodes in their class. They are designed to deliver great speed and efficiency for high frequency applications.
The silicon carbide (SiC) Schottky diodes released 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.
Key Applications
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 QC 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.
