VS-VSKH250-14PBF

SCRs - Modules Overview

The VS-VSKH250-14PBF is a high-power module diode manufactured by Vishay General Semiconductor - Diodes Division. It features a Magn-A-Pak package and is rated for a continuous forward current of 250A. The device supports a repetitive peak reverse voltage of 1400V, making it suitable for demanding industrial applications. The component is RoHS compliant and operates within an ambient temperature range up to 125°C. It is designed for chassis mounting and utilizes a specific terminal configuration to handle high thermal loads efficiently.

SCRs - Modules Feature Summary

• High current handling capability with a 250A rating
• Robust reverse voltage blocking at 1400V
• Thermal management optimized for Magn-A-Pak packaging

SCRs - Modules Applications

• Industrial motor drives
• Welding equipment rectifiers
• Uninterruptible power supply (UPS) systems

SCRs - Modules Procurement Notes

Verify the specific suffix 'PBF' indicates lead-free compliance when sourcing. Confirm that the Magn-A-Pak mechanical dimensions match the target chassis design. Ensure the supplier provides official datasheets confirming the 1400V rating and 250A current capacity. Check for AEC-Q101 qualification if automotive use is intended, though this part is primarily industrial.

SCRs - Modules Selection Notes

Select this module for applications requiring high surge current tolerance and robust reverse blocking. Compare thermal resistance values against heat sink capabilities. Ensure the operating environment does not exceed the specified junction temperature limits. Consider parallel configurations if higher current sharing is needed beyond single unit ratings.

SCRs - Modules Part Context

This component belongs to the VSKH series of high-power diode modules from Vishay. These modules are engineered for heavy-duty rectification tasks where standard discrete diodes cannot meet current or voltage requirements. The Magn-A-Pak form factor allows for efficient cooling and compact integration into larger power conversion assemblies.

SCRs - Modules Replacement Considerations

Direct substitutes must match the 250A current, 1400V voltage, and Magn-A-Pak footprint. Verify pinout compatibility before substitution. Cross-reference thermal characteristics to ensure equivalent performance under load.
