VS-VSKH71/04

SCRs - Modules Overview

The VS-VSKH71/04 is a thyristor/diode module from the AAP Gen 7 series, rated for 75 A average on-state current and 400 V repetitive peak reverse voltage. It utilizes an exposed direct bonded copper substrate to achieve low thermal resistance of 0.29 °C/W per leg. The device supports high surge currents up to 1360 A at 60 Hz and operates within a junction temperature range of -40 °C to +125 °C.

SCRs - Modules Procurement Notes

Verify the specific circuit configuration code 'H' (SCR/diode doubler circuit, positive control) against the datasheet ordering information table. Confirm that the voltage code '04' corresponds to the required 400 V rating. Ensure mounting hardware complies with the specified torque requirements for the TO-240AA case style.

SCRs - Modules Selection Notes

Select this component when a combined SCR and diode solution in a single package is required for positive control doubler circuits. Evaluate thermal management based on the 0.29 °C/W junction-to-case resistance and the maximum allowable case temperature curves provided in the datasheet for the expected conduction angle.

SCRs - Modules Part Context

This module belongs to the VS-VSK.71 series, which includes variants with different voltage codes and circuit configurations such as T, L, and N. The VS-VSKH71/04 specifically integrates one SCR and one diode in a doubler configuration, distinguishing it from pure thyristor or common anode modules within the same physical footprint.

SCRs - Modules Replacement Considerations

Other parts in the VS-VSK.71 series share the same mechanical dimensions and thermal characteristics. Verify compatibility by checking the circuit configuration code and voltage rating. No specific substitute part numbers are confirmed in the public documentation.
