Procurement Notes

Verify the specific part number suffix against official documentation to confirm packaging orientation and compliance status. The provided datasheet indicates that ordering suffixes define packing types such as tape and reel or bulk, alongside version codes for halogen-free or RoHS compliance. Ensure the selected variant matches the required mechanical mounting and environmental specifications for the target design.

Selection Notes

Select this component for designs requiring robust current handling in low-voltage environments. The TO-220AB package facilitates effective heat dissipation through direct mounting to a heatsink. Consider the derating curves for operation above ambient temperatures and ensure the circuit layout accommodates the axial lead configuration for proper mechanical stability and electrical isolation.

Part Context

This component belongs to the SB1620CT through SB1660CT series of Isolation Schottky Barrier Rectifiers. The series covers voltage ratings from 20 V to 60 V while maintaining a consistent 16 A current rating across all variants. The SB1645CT specifically addresses applications needing a 45 V blocking voltage threshold within this standardized product family.

Replacement Considerations

Direct substitutes within the same series include SB1620CT, SB1630CT, SB1640CT, SB1650CT, and SB1660CT. These parts share identical physical dimensions and thermal characteristics but differ in maximum repetitive peak reverse voltage ratings. Verify that the alternative voltage rating meets or exceeds the circuit requirements.
