Diode Arrays Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm electrical ratings and physical dimensions. Ensure that the procurement channel provides authentic components with traceable manufacturing data. Cross-reference the datasheet specifications for thermal management requirements during integration.

Diode Arrays Selection Notes

Select this component when a robust Schottky rectifier with high current capacity and low forward voltage drop is required. Consider the TO-249AB package for efficient heat dissipation and mounting flexibility. Evaluate the 45 V reverse voltage rating against circuit peak inverse voltage requirements to ensure reliable operation under all load conditions.

Diode Arrays Part Context

This component belongs to the FST120xx series of silicon power Schottky diodes. The series offers various voltage ratings ranging from 45 V to 100 V while maintaining a consistent 120 A average forward current rating. All variants share the same TO-249AB package and thermal characteristics, allowing for design flexibility across different voltage levels.

Diode Arrays Replacement Considerations

Compatible substitutes within the same series include the FST12060, FST12080, and FST120100. These parts share identical current and thermal specifications but offer higher repetitive peak reverse voltage ratings of 60 V, 80 V, and 100 V respectively.
