1N6660CCT1

Overview

The 1N6660CCT1 is a center-tap Schottky rectifier designed for IR HiRel environments. It features a common cathode configuration with a maximum DC reverse voltage of 45 V and an average forward current of 15 A. The device exhibits a maximum forward voltage of 750 mV at 15 A and a reverse leakage current of 1 mA at 45 V. Capacitance is specified as 2000 pF at 5 V and 1 MHz. Operating junction temperature ranges from -65°C to 150°C. The component utilizes a TO-254AA package with ceramic feed-through terminals.

Feature Summary

• Center-tap Schottky rectifier architecture optimized for high-reliability applications
• Ceramic feed-through terminal construction for robust environmental performance
• Common cathode configuration supporting dual-diode functionality

Applications

• IR HiRel power supply circuits
• High-reliability rectification systems
• Military aerospace electronic equipment

Procurement Notes

Verify the specific manufacturer designation, as sourcing data references both Microsemi Corporation and Microchip Technology for this part number. Confirm RoHS compliance status, as related listings indicate non-compliance. Ensure the ordering suffix CCT1 matches the required ceramic feed-through package variant rather than standard leaded versions. Validate that the supplier provides official documentation confirming the HiRel design intent and material specifications.

Selection Notes

Select this component when a center-tap Schottky rectifier with ceramic feed-through construction is required for high-reliability environments. The 45 V rating and 15 A current capacity suit moderate-voltage power conversion tasks. Consider the common cathode topology for bridge or full-wave rectifier configurations. Verify thermal management requirements given the 150°C junction limit and ensure the TO-254AA footprint fits the target PCB layout constraints.

Part Context

This part belongs to the 1N6660 series of Schottky diodes manufactured by Microsemi/Microchip. The series includes variants such as 1N6660DT1 and 1N6660CAT1, differing primarily in packaging and terminal style. The 1N6660CCT1 specifically denotes the center-tap version with ceramic feed-through terminals, distinguishing it from standard plastic encapsulated counterparts used in commercial applications.
