VS-VSKN91/14

SCRs - Modules Overview

The Vishay VS-VSKN91/14 is a thyristor/diode module rated for 1400 V repetitive peak reverse voltage and 95 A average on-state current. It utilizes the AAP Gen 7 (TO-240AA) package with an exposed direct bonded copper substrate for low thermal resistance. The device features a maximum non-repetitive surge current of 2000 A at 50 Hz and 2094 A at 60 Hz, alongside a maximum junction temperature of +125 °C.

SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'N' corresponds to the required SCR/diode common anode topology. Confirm that the 1400 V rating aligns with system voltage requirements. Ensure mounting hardware complies with the specified torque values for the TO-240AA case style to maintain thermal interface integrity.

SCRs - Modules Selection Notes

Select this component when a combined thyristor and diode solution in a single package is required. The common anode configuration simplifies circuit design for specific doubler or bridge topologies. Evaluate thermal management needs based on the 0.22 °C/W junction-to-case thermal resistance under DC operation conditions.

SCRs - Modules Part Context

This part belongs to the VS-VSKN91 series within the broader VS-VSKT91, VS-VSKH91, VS-VSKL91, and VS-VSKN91 family. These modules share the same physical dimensions and general electrical characteristics but differ in internal circuit configurations. The 'N' suffix specifically denotes the SCR/diode common anodes arrangement.

SCRs - Modules Replacement Considerations

Direct replacements must match the 1400 V rating, 95 A current capacity, and the specific SCR/diode common anode circuit configuration. Verify compatibility with the ADD-A-PAK Generation VII (TO-240AA) mechanical outline.
