FYP2045DNTU

Diode Arrays Overview

The FYP2045DNTU is a dual common cathode Schottky barrier rectifier manufactured by onsemi, originally designed by Fairchild Semiconductor. It features two independent diodes in a single TO-220 package with an average forward current rating of 20 A at a case temperature of 120°C and a maximum repetitive reverse voltage of 45 V. The device exhibits low forward voltage drop characteristics, with values ranging from 0.49 V to 0.70 V depending on the junction temperature and current load. It supports a non-repetitive peak surge current of 150 A and operates within a junction temperature range of -65°C to +150°C.

Diode Arrays Feature Summary

• Dual common cathode configuration for efficient power conversion
• Guard ring structure provides enhanced over-voltage protection
• Low forward voltage drop minimizes conduction losses
• High frequency switching capability suitable for modern power supplies

Diode Arrays Applications

• Switched mode power supplies (SMPS)
• Freewheeling diode circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify component authenticity through authorized distributors as this part originates from legacy Fairchild Semiconductor manufacturing lines now under onsemi. Confirm that the TO-220 package dimensions match your PCB footprint requirements. Ensure thermal management solutions account for the specified junction-to-case thermal resistance during high-current operation to maintain reliability within the stated temperature limits.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with a 45 V rating and 20 A continuous current capacity is required in a through-hole package. Consider the specific forward voltage characteristics at expected operating temperatures to ensure efficiency targets are met. Evaluate the thermal resistance specifications against your heatsinking capabilities to prevent junction overheating during peak load conditions.

Diode Arrays Part Context

This device belongs to the FYP2045DN series of Schottky barrier rectifiers. Originally developed by Fairchild Semiconductor, the product line was integrated into onsemi's portfolio following corporate acquisitions. The FYP2045DNTU variant specifically denotes the TO-220 through-hole packaging option, distinguishing it from surface-mount alternatives within the same electrical specification family.
