FST16045

Diode Arrays Overview

The FST16045 is a silicon power Schottky diode manufactured by GeneSiC Semiconductor, housed in a TO-249AB package. It features a repetitive peak reverse voltage of 45 V and an average forward current rating of 160 A per package. The device supports a maximum instantaneous forward surge current of 1000 A. Electrical characteristics include a maximum instantaneous forward voltage of 0.75 V at Tj = 25 °C and a thermal resistance from junction to case of 0.50 °C/W per leg. The component operates within a temperature range of -55 °C to 150 °C.

Diode Arrays Feature Summary

• High surge capability for handling transient current loads
• Isolated construction allows direct mounting to heatsinks or chassis plates
• Robust packaging designed for high-power density applications

Diode Arrays Applications

• Chassis mount rectification circuits
• Free-wheeling diodes in DC-DC converters
• Power supply output rectification

Diode Arrays Procurement Notes

Verify the specific part marking against the official datasheet to confirm the 45V rating and 160A current capacity. Ensure the TO-249AB package dimensions match the required mechanical constraints. Confirm that the supplier provides documentation verifying compliance with RoHS standards and lead-free manufacturing processes before finalizing orders.

Diode Arrays Selection Notes

Select this component when a low forward voltage drop is critical for efficiency in high-current applications. The isolated tab design simplifies thermal management by allowing direct attachment to a cold plate. Consider the 0.50 °C/W thermal resistance for calculating junction temperatures under continuous load conditions to ensure reliable operation within the specified temperature limits.

Diode Arrays Part Context

This device belongs to the FST160xx series of silicon power Schottky diodes, which ranges from 45 V to 100 V ratings. All members of this family share the same 160 A average forward current capability and utilize the TO-249AB package. The series is engineered for high-efficiency rectification where low conduction losses are prioritized over blocking voltage extremes.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include the FST16060 (60 V), FST16080 (80 V), and FST160100 (100 V). These parts maintain identical current and thermal specifications but offer higher reverse voltage ratings. Verify that the increased voltage rating does not conflict with circuit design requirements.
