Single Diodes Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches your assembly requirements. Confirm that the TO-220AC package dimensions align with your PCB footprint and thermal management design. Ensure the component meets all relevant environmental compliance standards required for your final product certification before placing orders.

Single Diodes Selection Notes

Select this component when a high-voltage, high-current ultrafast diode is required for boost applications. The 1200 V rating provides sufficient headroom for industrial and commercial power supplies. Consider the 175°C junction temperature rating for high-temperature environments. The TO-220AC package facilitates effective heat dissipation for continuous 15 A operation without excessive thermal resistance.

Single Diodes Part Context

This part belongs to STMicroelectronics' STTH series of ultrafast recovery diodes. The series utilizes proprietary Turbo 2 technology to achieve low reverse recovery charge and fast switching speeds. These diodes are engineered to minimize switching losses in hard-switching topologies, offering improved efficiency compared to standard ultrafast diodes in similar voltage and current classes.

Single Diodes Replacement Considerations

Direct substitutes must match the 1200 V / 15 A rating, TO-220AC package, and ultrafast recovery characteristics. Verify reverse recovery time and forward voltage specifications to ensure equivalent circuit performance. Consult official cross-reference lists for confirmed compatible parts from other manufacturers.
