VS-VSKH41/12

SCRs - Modules Overview

The VS-VSKH41/12 is a thyristor module manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V repetitive off-state voltage and a 100 A RMS on-state current capability. The device utilizes a series SCR/diode configuration within an ADD-A-PAK (3 + 4) base-mount package. Key electrical specifications include a maximum gate trigger voltage of 2.5 V and a maximum gate trigger current of 150 mA. Non-repetitive surge currents are rated at 850 A for 50 Hz and 890 A for 60 Hz frequencies. The component operates within a junction temperature range of -40°C to 125°C.

SCRs - Modules Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm exact voltage and current ratings, as variations exist within the VSKH41 family. Ensure that the procurement channel provides valid traceability documents confirming compliance with RoHS3 requirements. Cross-reference the package type to guarantee compatibility with existing chassis mounting hardware and thermal interface materials used in the target assembly.

SCRs - Modules Selection Notes

Select this component when a combined SCR and diode functionality is required in a single base-mounted package. Evaluate the 800 V blocking capability against peak circuit voltages to ensure adequate safety margins. Consider the 100 A RMS rating relative to continuous load requirements and derating factors. Confirm that the ADD-A-PAK form factor fits within the mechanical constraints of the intended enclosure and cooling system.

SCRs - Modules Part Context

This part belongs to the VSKH41 series of thyristor modules from Vishay. The series offers various voltage ratings including 400 V, 600 V, 800 V, 1 kV, 1.2 kV, 1.4 kV, and 1.6 kV options, all sharing similar current capabilities and packaging styles. This specific model represents the 800 V variant within that lineup.

SCRs - Modules Replacement Considerations

Direct substitutes within the same manufacturer line include VS-VSKH41/08 (800 V), VS-VSKH41/06 (600 V), and VS-VSKH41/10 (1 kV). Verify that alternative voltage ratings meet the circuit's peak inverse voltage requirements before substitution.
