SCRs - Modules Procurement Notes
This component reached End of Life in December 2024. Procurement must be verified through authorized channels or direct contact with Vishay to confirm availability of remaining stock or alternative solutions. Verify that the specific ordering suffix matches the required electrical ratings before acquisition.
SCRs - Modules Selection Notes
Selection requires matching the 1200 V blocking voltage and 500 A continuous current rating to the application load. Thermal management must account for the 0.065 K/W junction-to-case thermal resistance. Ensure gate drive circuits can supply the required 200 mA DC trigger current while respecting the 10 W peak gate power limit.
SCRs - Modules Part Context
The VS-VSKH500-12PBF belongs to the VSK.500 series of Super MAGN-A-PAK power modules. This series includes thyristor/thyristor (KT), thyristor/diode (KH), and diode/thyristor (KL) configurations. The 'KH' designation specifically indicates a thyristor/diode doubler circuit configuration.
SCRs - Modules Replacement Considerations
Contact Vishay directly for alternative solutions as this part is discontinued. Cross-reference within the VSK.500 series for similar voltage and current ratings if available.
