FST16145

Diode Arrays Overview

The FST16145 is a Schottky PowerMod diode module manufactured by Microsemi Corporation. It features a common cathode configuration with two independent diodes housed in a TO-247 flatpack package. The device is rated for a maximum repetitive peak reverse voltage of 45V and a continuous forward current of 80A. Key electrical characteristics include a maximum DC forward voltage drop of 0.93V at specified conditions and a maximum non-repetitive surge forward current capability of 1200A. The component utilizes an electrically isolated base design to facilitate thermal management and mounting.

Diode Arrays Feature Summary

• Schottky barrier rectifier technology for low forward voltage drop
• Electrically isolated base for efficient heat dissipation
• Common cathode dual diode configuration
• High surge current handling capability

Diode Arrays Applications

• DC/DC converter output rectification
• Free-wheeling diodes in power supplies
• Inductive load protection circuits
• Solar panel bypass applications

Diode Arrays Procurement Notes

Verify the specific suffix designation when ordering, as variants such as FST16145D exist with different package types like TO-249. Confirm RoHS compliance status and lead-free requirements with the supplier prior to purchase. Ensure that the thermal interface material and mounting hardware are compatible with the flatpack or alternative package style selected. Cross-reference the manufacturer's latest datasheet to confirm pinout compatibility and mechanical dimensions for PCB layout integration.

Diode Arrays Selection Notes

Select this component for applications requiring high current rectification with minimal voltage loss. The 45V rating suits low-voltage DC systems where efficiency is critical. Consider the thermal resistance of the package when designing heatsinking solutions. Evaluate the surge current rating against potential inrush currents in the target circuit to ensure reliability under transient conditions.

Diode Arrays Part Context

This part belongs to the Schottky PowerMod series from Microsemi, designed for high-efficiency power conversion. It serves as a robust solution for replacing standard PN junction rectifiers in low-voltage, high-current scenarios. The series emphasizes thermal performance and switching speed advantages inherent to Schottky technology.

Diode Arrays Replacement Considerations

The FST16145D is a confirmed variant within the same product family, differing primarily in the package style (TO-249 instead of flatpack). Verify mechanical fit and thermal pad alignment when substituting between these package types.
