LSIC2SD170B25

Single Diodes Overview

The Littelfuse LSIC2SD170B25 is a Silicon Carbide Schottky Barrier Diode rated for 1700 V repetitive peak reverse voltage and 25 A continuous forward current at 150 °C case temperature. It features a TO-247-2L package with a maximum thermal resistance of 0.44 °C/W. The device supports a junction temperature range from -55 °C to 175 °C and exhibits zero reverse recovery current.

Single Diodes Feature Summary

• Positive temperature coefficient ensures safe operation and facilitates easy paralleling.
• Extremely fast, temperature-independent switching behavior dramatically reduces switching losses compared to silicon bipolar diodes.
• Zero reverse recovery current eliminates tail current issues during commutation.

Single Diodes Applications

• Boost diodes in PFC or DC/DC stages
• Switch-mode power supplies
• Solar inverters
• Uninterruptible power supplies
• Industrial motor drives

Single Diodes Procurement Notes

Verify the specific ordering suffix and lot number against the latest manufacturer datasheet before finalizing procurement. Confirm that the TO-247-2L package dimensions and mounting torque requirements align with the target PCB layout and heatsink interface specifications for the intended application design.

Single Diodes Selection Notes

Select this component for high-voltage applications requiring low switching losses and high thermal stability. Ensure the operating junction temperature remains within the specified -55 °C to 175 °C range. Evaluate the thermal management solution to maintain case temperatures within limits that support the required continuous forward current derating curves.
