• High voltage capability suitable for demanding power environments
• Isolated case connection for effective thermal management

Applications

• High voltage power supplies
• Industrial motor drives
• Inverter systems

Procurement Notes

Verify the manufacturer designation carefully, as historical documentation may list International Rectifier (Infineon) while current branding reflects Vishay. Confirm the specific suffix 'A' aligns with the required datasheet revision and regulatory compliance status. Ensure the TO-240AA footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a common anode topology is required for high-voltage rectification. The 1400 V rating provides sufficient margin for standard industrial AC line voltages. The TO-240AA package facilitates screw mounting for robust mechanical stability and efficient heat dissipation in high-current scenarios compared to smaller surface-mount alternatives.

Part Context

This part belongs to the family of high-power discrete semiconductor diodes designed for heavy-duty industrial use. It serves as a critical switching element in power conversion stages where reliability under high thermal stress is paramount. The component represents a transition point in manufacturing lineage between International Rectifier and Vishay Semiconductors.
