VS-VSKL105/12

SCRs - Modules Overview

The VS-VSKL105/12 is a thyristor/diode module from the VSK.105 series, rated for 1200 V repetitive peak off-state voltage and 105 A average on-state current. It utilizes an ADD-A-PAK (TO-240AA) package with exposed direct bonded copper substrate for low thermal resistance. The device features a maximum continuous RMS on-state current of 235 A as an AC switch and supports non-repetitive surge currents up to 2094 A at 60 Hz.

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 1200 V rating aligns with the system's maximum repetitive peak reverse voltage requirements. Ensure mounting hardware complies with the specified torque values for the AAP Gen 7 package.

SCRs - Modules Selection Notes

Select this component when a 1200 V blocking capability is required alongside high surge tolerance. The negative control doubler configuration is suitable for specific rectifier topologies. Evaluate thermal management needs based on the junction-to-case thermal resistance and expected conduction angles to ensure operation within the -40 °C to +130 °C junction temperature range.

SCRs - Modules Part Context

This module belongs to the VSK.105 series, which includes variants with different voltage ratings and circuit configurations such as T, H, L, and N.
