FST16020

Diode Arrays Overview

The GeneSiC Semiconductor FST16020 is a silicon power Schottky diode housed in a TO-249AB package. It features a repetitive peak reverse voltage of 20 V and an average forward current rating of 160 A per package. The device supports a maximum instantaneous forward voltage of 0.75 V and handles a peak forward surge current of 1000 A. Thermal resistance from junction to case is 0.50 °C/W per leg. Operating and storage temperatures range from -55 °C to 150 °C.

Diode Arrays Feature Summary

• High surge capability for robust transient handling
• Electrically isolated to the mounting plate
• Not sensitive to electrostatic discharge

Diode Arrays Applications

• Chassis mount power rectification
• DC-DC converter output stages
• Free-wheeling diodes in motor drives

Diode Arrays Procurement Notes

Verify the specific part marking against the datasheet terminal configuration diagram to ensure correct pinout alignment during installation. Confirm that the thermal interface material matches the required junction-to-case thermal resistance specifications for your heat sink design. Ensure the operating environment stays within the specified temperature limits to maintain reliability.

Diode Arrays Selection Notes

Select this component when a low forward voltage drop and high current capacity are required in a through-hole package. The 20 V rating suits low-voltage DC bus applications. Consider the 0.50 °C/W thermal resistance for heatsink calculations. Compare with higher voltage variants in the same series if system requirements change.

Diode Arrays Part Context

This device belongs to the FST160xx series of silicon Schottky diodes, which includes variants with different reverse voltage ratings such as 30 V and 40 V. All members share the same TO-249AB physical footprint and thermal characteristics, allowing for design flexibility while maintaining mechanical compatibility across the product line.

Diode Arrays Replacement Considerations

Direct substitutes include other FST160xx series parts like the FST16030 or FST16040, provided the lower reverse voltage rating of the FST16020 meets the circuit requirements. Verify that any replacement maintains the same TO-249AB package dimensions and thermal performance.
