VS-VSKT26/14

SCRs - Modules Overview

The VS-VSKT26/14 is a thyristor/diode doubler module from the AAP Gen 7 series, rated for 1400 V repetitive peak reverse voltage. It provides an average on-state current of 27 A at 85 °C case temperature and supports up to 60 A continuous RMS as an AC switch. The device withstands non-repetitive surge currents of 400 A (50 Hz) or 420 A (60 Hz). Operating within a junction temperature range of -40 °C to +125 °C, it utilizes an exposed direct bonded copper substrate for low thermal resistance.

SCRs - Modules Feature Summary

• Features high voltage blocking capability with industrial standard packaging
• Utilizes exposed direct bonded copper substrate for excellent thermal performance
• Designed and qualified for industrial level applications
• Includes UL approval file E78996

SCRs - Modules Applications

• High voltage regulated power supplies
• Lighting circuits
• Temperature control circuits
• Motor speed control circuits
• UPS systems and battery chargers

SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'T' corresponds to the required two SCR doubler topology. Confirm that the 1400 V rating aligns with system voltage requirements. Ensure mounting hardware complies with the specified 4 Nm torque recommendation for the TO-240AA package. Check RoHS compliance status against project specifications.

SCRs - Modules Selection Notes

Select this component when a thyristor/diode doubler circuit is needed in a compact form factor. The 27 A average current rating suits moderate power applications. Consider the 0.76 °C/W junction-to-case thermal resistance for heatsink design. Verify gate trigger parameters match the available drive circuit capabilities.

SCRs - Modules Part Context

This module belongs to the VS-VSKT26.. series, which includes variants with different voltage ratings ranging from 400 V to 1600 V. All share the same 27 A current rating and AAP Gen 7 (TO-240AA) package. The '14' suffix specifically denotes the 1400 V blocking voltage version within this standardized product family.

SCRs - Modules Replacement Considerations

Direct substitutes include other Vishay modules from the same series with identical current ratings but different voltage codes, such as VS-VSKT26/12 or VS-VSKT26/16, provided the voltage rating meets or exceeds the application requirement.
