SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'V' indicating common anodes before procurement. Confirm the voltage rating suffix '10' corresponds to the required 1000 V blocking capability. Ensure the application environment remains within the specified -40 to +125 °C operating temperature range. Check for compliance with material categorization definitions if required by project specifications.

SCRs - Modules Selection Notes

Select this component when a dual SCR configuration with common anodes is required for bridge or midpoint connections. The TO-240AA package facilitates efficient thermal management via direct bonded copper. Consider the 1000 V rating for general purpose high voltage applications. Verify that the gate triggering parameters align with the control circuit design requirements.

SCRs - Modules Part Context

This part belongs to the VS-VSKU71/VSKV71 series of AAP Gen 7 Thyristor modules. The 'V' suffix denotes a common anode circuit configuration, distinguishing it from the 'U' suffix which indicates common cathodes. Both variants share identical electrical ratings and mechanical dimensions, differing only in internal connectivity.

SCRs - Modules Replacement Considerations

Direct substitutes include other Vishay VS-VSKU71/10 units. Cross-series replacements must match the 75 A current rating, 1000 V voltage rating, and TO-240AA package footprint. Verify equivalent thermal resistance and gate trigger characteristics when considering alternative manufacturers.

SCRs - Modules FAQ

What is the difference between VS-VSKU71/10 and VS-VSKV71/10?

The primary difference is the internal circuit configuration. VS-VSKU71/10 features two SCRs with common cathodes, while VS-VSKV71/10 features two SCRs with common anodes.

What is the maximum non-repetitive surge current for this module?

The maximum non-repetitive peak on-state current is 1360 A for a duration of 8.3 ms (60 Hz) and 1300 A for 10 ms (50 Hz).

What is the recommended mounting torque for the heatsink?

The recommended mounting torque is 4 Nm ± 10%. Using a mounting compound is recommended, and the torque should be rechecked after 3 hours.
