Single Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm the exact package type and delivery mode. The E3 suffix indicates compliance with lead-free requirements and whisker testing standards. Confirm availability status as manufacturing locations or packaging formats may change without notice. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Single Diodes Selection Notes

Select this component for designs requiring high efficiency and low conduction losses at elevated temperatures. The ITO-220AB package provides electrical isolation between the terminal and heatsink, which is critical for safety in certain topologies. Evaluate the thermal management requirements based on the specified thermal resistance values to ensure reliable operation under continuous load conditions.

Single Diodes Part Context

This part belongs to the V20100SG family of high-voltage Trench MOS Barrier Schottky Rectifiers. The family includes variants such as V20100SG, VB20100SG, and VI20100SG, which share identical electrical specifications but differ in physical package configurations like TO-220AB, TO-263AB, and TO-262AA.
