VS-VSKN26/06

SCRs - Modules Overview

The VS-VSKN26/06 is a thyristor/diode module from the AAP Gen 7 series, featuring two SCRs with common anodes. It provides a maximum repetitive peak reverse voltage of 600 V and supports a maximum average on-state current of 27 A at 85 °C case temperature. The device handles continuous RMS currents up to 60 A as an AC switch and withstands non-repetitive surge currents of 400 A at 50 Hz or 420 A at 60 Hz. Operating within a junction temperature range of -40 °C to +125 °C, it utilizes direct bonded copper substrates for efficient thermal dissipation.

SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'N' corresponds to the required two-SCR common anode topology. Confirm the voltage suffix '06' matches the 600 V rating requirement. Ensure mounting hardware complies with the specified 4 Nm torque recommendation for optimal thermal interface contact. Validate that the application environment remains within the -40 °C to +125 °C operating limits.

SCRs - Modules Selection Notes

Select this component when a dual SCR common anode arrangement is necessary for high voltage DC applications. The 27 A average current rating suits moderate power levels requiring robust surge handling capabilities. Consider the low thermal resistance provided by the DBC substrate for effective heat management in constrained spaces. Verify compatibility with standard TO-240AA compatible heatsink mounting patterns.

SCRs - Modules Part Context

This module belongs to the VS-VSKT26.., VS-VSKH26.., VS-VSKL26.., and VS-VSKN26.. series, which share identical electrical ratings and mechanical dimensions.
