SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'L' corresponds to the required SCR/diode doubler circuit with negative control. Confirm that the 1600 V rating aligns with system voltage requirements. Ensure mounting hardware complies with the specified M5 x 0.8 screw torque of 4 Nm for the busbar connection. Validate thermal interface material compatibility for the recommended case-to-heatsink thermal resistance.

SCRs - Modules Selection Notes

Select this component when a combined SCR and diode solution in a single package is required for high voltage applications. The L suffix indicates a specific internal topology suitable for doubler circuits. Consider the 1600 V blocking capability and 105 A current rating against peak load demands. Evaluate the TO-240AA footprint for mechanical integration and heatsinking constraints.

SCRs - Modules Part Context

This part belongs to the VS-VSK105 series, which includes variants with different voltage ratings and circuit configurations. The 'L' designation specifically denotes an SCR/diode doubler circuit with negative control. Other series members include T, H, and N configurations, offering flexibility for various rectifier and converter topologies within the same physical package.

SCRs - Modules Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Verify compatibility with alternative Vishay modules such as VS-VSKT105/16 or VS-VSKH105/16 if the specific doubler circuit topology is not required. Cross-reference pinouts and thermal characteristics carefully.

SCRs - Modules FAQ

What is the internal circuit configuration of the VS-VSKL105/16?

It contains one SCR and one diode configured as an SCR/diode doubler circuit with negative control.

What is the maximum gate trigger voltage at cold start conditions?

The maximum gate voltage required to trigger is 4.0 V when the junction temperature is -40 °C.

How does the thermal resistance vary with conduction angle?

The incremental thermal resistance RthJC increases as the conduction angle decreases; for example, it rises from 0.04 °C/W at 180° to 0.125 °C/W at 30° conduction.
