VS-VSKV71/04

SCRs - Modules Overview

The VS-VSKV71/04 is a thyristor module from the Vishay VS-VSKV71.. series, featuring two SCRs with common anodes in an AAP Gen 7 (TO-240AA) package. It has a maximum repetitive peak reverse voltage of 400 V and supports an average on-state current of 75 A at 85 °C case temperature. The continuous RMS on-state current reaches 115 A under DC conditions. Non-repetitive surge currents are rated at 1360 A for 8.3 ms pulses. The junction operating temperature range spans from -40 °C to +125 °C.

SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'V' indicating common anodes before procurement. Confirm that the 400 V voltage rating aligns with system requirements. Ensure mounting hardware complies with the specified torque values for reliable thermal interface. Check for updated product change notifications regarding manufacturing sources or material categorization updates prior to finalizing orders.

SCRs - Modules Selection Notes

Select this component when a dual SCR configuration with common anodes is required for high voltage applications. The TO-240AA package facilitates efficient heat dissipation through direct bonded copper substrates. Consider the 75 A average current rating relative to the expected case temperature and conduction angle. Verify insulation voltage ratings if isolation requirements exceed standard specifications.

SCRs - Modules Part Context

This part belongs to the VS-VSKU71.. and VS-VSKV71.. series, which share identical electrical characteristics but differ in internal circuit topology. The 'V' suffix specifically denotes a common anode configuration, whereas 'U' indicates common cathodes. Both variants utilize the same AAP Gen 7 mechanical housing and thermal management design principles.

SCRs - Modules Replacement Considerations

Direct substitutes within the same series include VS-VSKU71/04 for common cathode configurations. Other voltage codes such as VS-VSKV71/08 or VS-VSKV71/12 offer higher blocking voltages while maintaining the same current ratings and package dimensions.
