- The devices, featuring a common cathode configuration, can withstand IOL cycles up to five times that of the previous TO-244 generation.
- This enhancement improves the modules’ life expectancy while simultaneously reducing losses.
Vishay Intertechnology, Inc. have announced the release of two new FRED Pt 500 A Ultrafast soft recovery diode modules in the innovative TO-244 Gen III package. The new modules, VS-VSUD505CW60 and VS-VSUD510CW60, offer higher reliability compared to previous-generation solutions, aiming to reduce losses and EMI / RFI in high frequency power conditioning systems.
The rugged package of the diode modules can withstand 46,000 IOL cycles under specified conditions, providing an improved life expectancy over previous-generation devices. The industry-standard package is footprint-compatible with competing solutions in the package, allowing for a seamless drop-in replacement for existing designs.
Key Features of the Diode Modules are:
- Ultrafast recovery
- Designed for industrial level
- UL approved file E222165
These diode modules are ideally suited for applications such as high frequency welding, high current converters, ballast water management systems (BWMS) in railway equipment, cranes, and ships, UPS, and other applications where switching losses contribute significantly to the total losses. The softness of their recovery eliminates the need for a snubber in these applications, reducing component counts and lowering costs. Offered in a common cathode configuration, the diode modules provide low forward voltage drop down to 0.82 V, thermal resistance — junction to case — of 0.16 °C/W, and an operating temperature range up to +175 °C. Samples and production quantities of the new FRED Pt soft recovery diode modules are available now, with lead times of 26 weeks.
