FST10045

Diode Arrays Overview

The GeneSiC Semiconductor FST10045 is a silicon power Schottky rectifier housed in a TO-249AB package. It features a repetitive peak reverse voltage of 45 V and an average forward current rating of 100 A per package. The device exhibits a maximum instantaneous forward voltage of 0.70 V and supports a peak forward surge current of 1000 A. Thermal resistance from junction to case is 1.0 °C/W per leg. Operating and storage temperatures range from -55 °C to +150 °C.

Diode Arrays Feature Summary

• High surge capability with robust transient handling
• Electrically isolated base plate for mounting flexibility
• Not ESD sensitive for simplified handling

Diode Arrays Applications

• Power supply circuits requiring high efficiency

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 environment stays within the stated temperature limits to maintain reliability.

Diode Arrays Selection Notes

Select this component when a 45 V blocking voltage and 100 A continuous current are required in a TO-249AB form factor. Consider the low forward voltage drop for efficiency optimization. Evaluate the thermal management strategy based on the 1.0 °C/W junction-to-case resistance to ensure the junction temperature remains below 150 °C under load.

Diode Arrays Part Context

This device belongs to the FST100 series, which includes variants with ratings up to 100 V. The series shares common packaging and thermal characteristics while differing in reverse voltage capabilities. It is designed for general-purpose power rectification where low loss and high reliability are critical.

Diode Arrays Replacement Considerations

Compatible substitutes include FST10060, FST10080, and FST100100 from the same manufacturer series. These alternatives offer higher voltage ratings but share identical current and thermal specifications.
