FST16090D

Diode Arrays Overview

The FST16090D is a Schottky Barrier Rectifier Doubler module manufactured by Microsemi Corporation. It features a maximum repetitive peak reverse voltage of 90V and an average forward current rating of 80A per leg. The device utilizes a TO-249AA package with nickel-plated copper pins and an electrically isolated baseplate. Key electrical characteristics include a maximum instantaneous forward voltage of 0.96V at 80A and a typical junction capacitance of 1500pF. The component supports a maximum surge current of 1200A and operates within a junction temperature range of -55°C to 175°C.

Diode Arrays Feature Summary

• Schottky barrier rectifier doubler configuration for high-efficiency power conversion
• Electrically isolated nickel-plated copper baseplate for secure mounting
• High surge current capacity designed for demanding transient loads

Diode Arrays Applications

• High-frequency switching power supplies
• DC-DC converter output rectification
• Industrial motor drive freewheeling circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'D' confirms the Doubler configuration, as 'A' denotes Common Anode. Confirm that the manufacturer has not issued a Product Change Notification (PCN) altering the physical dimensions or electrical parameters. Ensure compliance with RoHS directives if required by the end application. Review the datasheet for derating curves to validate thermal performance under actual operating conditions.

Diode Arrays Selection Notes

Select this component when a doubler topology is required for low-voltage, high-current applications. The 90V reverse voltage rating suits systems where input fluctuations remain below this threshold. Evaluate the thermal resistance from junction to case to ensure adequate heat sinking. Compare the forward voltage drop against standard rectifiers to assess efficiency gains in high-current scenarios.

Diode Arrays Part Context

This part belongs to the FST160 series of Schottky Powermod devices from Microsemi. The series includes variants with different reverse voltage ratings, such as the FST160100. These modules are engineered for robust performance in power electronics, offering superior switching speeds compared to conventional silicon rectifiers while maintaining high current handling capabilities.

Diode Arrays Replacement Considerations

The FST160100 serves as a direct functional substitute with a higher 100V reverse voltage rating. Verify that the increased voltage margin does not impact system design constraints. Ensure mechanical compatibility with existing TO-249AA footprints and mounting hardware.
