Procurement Notes

Verify the specific ordering suffix matches the required electrical characteristics and packaging format. Confirm that the TO-247-3 lead frame compatibility aligns with your PCB footprint requirements. Ensure the supplier provides valid RoHS compliance documentation. Cross-reference the manufacturer's latest datasheet for any potential specification updates or pinout revisions before finalizing procurement orders.

Selection Notes

Select this component when operating voltages exceed 600V and high-frequency switching is required. The SiC material choice is critical for applications demanding reduced heat dissipation and higher efficiency. Consider the 1200V rating for safety margins in industrial power supplies. Evaluate the thermal resistance of the TO-247-3 package against your heatsinking capabilities to maintain junction temperature within safe limits during continuous operation.

Part Context

This part belongs to SemiQ’s Amp+ series of wide-bandgap power devices. It represents a shift towards silicon carbide technology in standard through-hole packages, bridging the gap between discrete components and module-level integration. The series emphasizes reliability and efficiency in modern power electronics architectures.

Replacement Considerations

Direct substitutes must match the 1200V/30A SiC Schottky specifications and TO-247-3 form factor. Verify equivalent forward voltage and reverse leakage characteristics to ensure identical thermal performance. Check for compatible mounting hole dimensions and lead spacing to avoid mechanical redesign.
