VS-VSKT142/12PBF

SCRs - Modules Overview

The VS-VSKT142/12PBF is a silicon SCR module manufactured by Vishay General Semiconductor - Diodes Division. It features a common cathode configuration within an INT-A-PAK(3) base-mount package. The device supports a rated repetitive off-state voltage of 1.2 kV and handles a maximum RMS on-state current of 310 A, with an average on-state current rating of 140 A. It withstands non-repetitive surge currents of 4.5 kA at 50 Hz and 4.712 kA at 60 Hz. Gate triggering requires a maximum voltage of 2.5 V and current of 150 mA, while the holding current is limited to 200 mA. Operating junction temperature ranges from -40°C to +125°C.

SCRs - Modules Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm voltage ratings, as the model number indicates a 1.2 kV variant. Ensure the INT-A-PAK(3) package dimensions match the mechanical design constraints. Confirm RoHS3 compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate gate trigger parameters against the specific application circuit requirements before finalizing procurement.

SCRs - Modules Selection Notes

Select this component when a common cathode SCR module is required for high-current applications up to 310 A RMS. The 1.2 kV blocking voltage suits medium-voltage industrial environments. The INT-A-PAK(3) package facilitates efficient heat dissipation via base mounting. Verify that the gate drive circuit can supply the specified 2.5 V and 150 mA limits. Consider the operating temperature range and surge current capabilities relative to the system's fault conditions.

SCRs - Modules Part Context

This part belongs to the Vishay VS-VSKT series of silicon controlled rectifier modules. These modules are designed for high-power switching applications requiring robust performance and reliability. The INT-A-PAK packaging provides a standardized form factor for integration into power electronics assemblies. Vishay utilizes advanced silicon technology to ensure consistent electrical characteristics across the product line.

SCRs - Modules Replacement Considerations

Official substitutes include the VS-VSKT142/14PBF, which shares the same package but offers a higher 1.4 kV voltage rating. Verify pinout compatibility and thermal resistance values when substituting. Ensure the replacement part meets or exceeds the original 310 A RMS current requirement.
