FST10040

Diode Arrays Overview

The GeneSiC Semiconductor FST10040 is a silicon power Schottky diode module housed in a TO-249AB package. It features an average forward current rating of 100 A per leg and a repetitive peak reverse voltage of 40 V. The device supports a maximum instantaneous forward voltage of 0.70 V and offers a peak forward surge current capability of 1000 A per leg. Thermal resistance from junction to case is specified at 1.0 °C/W per leg. The component operates within a temperature range of -55 °C to 150 °C.

Diode Arrays Feature Summary

• High surge current capability for robust transient handling
• Electrical isolation between the semiconductor junction and the mounting plate
• Resistance to electrostatic discharge damage during handling

Diode Arrays Applications

• DC-DC converter circuits requiring high efficiency
• Free-wheeling rectification in motor drive systems

Diode Arrays Procurement Notes

Verify the specific part marking against the datasheet terminal configuration diagram to ensure correct pinout alignment. Confirm that the thermal interface material selection matches the specified junction-to-case thermal resistance requirements for your heat sink design. Ensure the operating voltage does not exceed the 40 V repetitive peak reverse voltage limit under all transient conditions.

Diode Arrays Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency. The TO-249AB package facilitates direct chassis or heatsink mounting, simplifying thermal management in compact designs. Consider the 1000 A surge rating if the application involves significant inrush currents or short-circuit protection scenarios.

Diode Arrays Part Context

This device belongs to the FST100 series of silicon Schottky diodes from GeneSiC Semiconductor. The series includes variants with different reverse voltage ratings, such as the FST10020 (20 V) and FST10030 (30 V), while maintaining identical current and thermal characteristics across the lineup.

Diode Arrays Replacement Considerations

Direct substitutes include other models within the FST100 series, specifically the FST10020 and FST10030, provided the lower voltage ratings are sufficient for the circuit application.
