Diode Arrays Procurement Notes

Verify the specific suffix KKHPSA1 against official datasheets to confirm pinout and thermal characteristics. Ensure compatibility with existing cooling systems given the 350 A rating. Confirm availability status as production cycles may vary. Cross-reference with Infineon's official documentation for any recent design changes or obsolescence notices before finalizing procurement plans.

Diode Arrays Selection Notes

Select this module when a 1200 V blocking capability and 350 A continuous current are required in a compact form factor. The MODULE-3 package offers standardized mounting options. Consider the thermal resistance and required heatsinking for the 150 °C junction temperature limit. Evaluate the I²t value for short-circuit protection coordination in the system design.
