VS-VSKT136/16PBF

SCRs - Modules Overview

The VS-VSKT136/16PBF is a silicon SCR module manufactured by Vishay Semiconductors, housed in the INT-A-PAK package with screw mount installation. It features a rated repetitive off-state voltage (VDRM) of 1.6 kV and an on-state RMS current (IT RMS) of 300 A. The non-repetitive peak on-state current is 3.2 kA, with a maximum on-state voltage of 1.57 V. Gate trigger current (IGT) is specified at 150 mA, and holding current (IH max) is 200 mA. Operating temperature ranges from -40°C to +125°C.

SCRs - Modules Feature Summary

• High power handling capability with 300 A RMS current rating in a compact INT-A-PAK form factor
• Robust surge tolerance with 3.2 kA non-repetitive peak on-state current capacity
• Standardized gate control characteristics requiring 150 mA trigger current for reliable switching

SCRs - Modules Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supply rectification circuits
• Welding equipment power stages
• HVDC transmission control systems

SCRs - Modules Procurement Notes

Verify the specific suffix '16' corresponds to the 1.6 kV voltage rating when sourcing replacements. Confirm that the INT-A-PAK mounting hole pattern matches the existing thermal interface design. Ensure gate drive circuitry provides sufficient current exceeding the 150 mA IGT specification for reliable turn-on under all operating conditions.

SCRs - Modules Selection Notes

Select this component when a 1.6 kV blocking voltage and 300 A continuous current are required in a chassis-mountable module. Compare against lower voltage variants like the /12PBF or /08PBF if system voltage permits downsizing. Consider thermal management requirements given the 1.57 V on-state drop at high currents.

SCRs - Modules Part Context

This part belongs to Vishay's VSKT series of thyristor modules designed for high-power industrial applications. The INT-A-PAK packaging allows for efficient heat dissipation through direct chassis mounting. It complements other variants in the family differentiated primarily by their voltage ratings while maintaining consistent current and thermal performance characteristics.

SCRs - Modules Replacement Considerations

Direct substitutes include VS-VSKT136/12PBF and VS-VSKT136/08PBF for lower voltage applications. Verify pinout compatibility and thermal resistance values before swapping between different voltage ratings within the same current-rated series.
