Procurement Notes

Verify the exact suffix and manufacturer designation when sourcing, as Littelfuse acquired IXYS. Confirm the specific current rating variant required for your design, as the series covers multiple peak drive currents. Ensure the TO-263-5 package matches your PCB footprint requirements. Cross-reference datasheets to confirm pinout compatibility with existing designs.

Selection Notes

Select this component for applications requiring reliable low-side switching with wide voltage tolerance. Consider the thermal performance of the TO-263 package for heat dissipation needs. Evaluate the peak drive current capability against the target switch's gate charge requirements. Verify that the logic input levels are compatible with the controlling microcontroller or FPGA.
