FST16080

Diode Arrays Overview

The GeneSiC Semiconductor FST16080 is a silicon power Schottky diode housed in a TO-249AB package. It features a repetitive peak reverse voltage of 80 V and an average forward current rating of 160 A per package. The device supports a maximum instantaneous forward voltage of 0.84 V at Tj = 150 °C and handles a peak forward surge current of 1000 A. Operating temperatures range from -55 °C to +150 °C, with a junction-to-case thermal resistance of 0.50 °C/W per leg.

Diode Arrays Feature Summary

• High surge current capability for robust transient handling
• Electrically isolated structure to the mounting plate
• Non-sensitive design regarding electrostatic discharge

Diode Arrays Applications

• High-frequency rectification in power conversion circuits

Diode Arrays Procurement Notes

Verify the specific part marking against the datasheet terminal configuration diagram to ensure correct pinout identification. Confirm that the thermal interface material selection aligns with the specified junction-to-case thermal resistance value for proper heat dissipation. Ensure the mounting torque specifications are strictly followed to maintain electrical isolation integrity and mechanical stability during operation.

Diode Arrays Selection Notes

Select this component when an 80 V blocking voltage and 160 A continuous current capacity are required within a TO-249AB form factor. Consider the 0.84 V forward voltage drop at elevated temperatures for efficiency calculations. Evaluate the 0.50 °C/W thermal resistance against your heatsink capabilities to ensure the junction temperature remains within the -55 °C to +150 °C operating range under expected load conditions.

Diode Arrays Part Context

This device belongs to the FST160xx series, which includes variants ranging from 45 V to 100 V repetitive reverse voltage. All members share identical physical dimensions, thermal characteristics, and current ratings, differing only in their voltage blocking capabilities. This standardization allows for flexible design scaling while maintaining consistent mechanical integration requirements across the product family.

Diode Arrays Replacement Considerations

Direct substitutes include other FST160xx series parts such as FST16045 or FST160100 if voltage ratings differ from system requirements. Cross-brand replacements must match the TO-249AB package, 160 A current rating, and 0.50 °C/W thermal resistance to ensure compatibility without redesigning the PCB or thermal management system.
