SDURF1660CTR

Diode Arrays Overview

The SDURF1660CTR is a dual Schottky barrier rectifier manufactured by SMC Diode Solutions, housed in an isolated TO-220AB (ITO-220AB) through-hole package. It features a common anode configuration with two independent cathodes. The device supports a maximum repetitive peak reverse voltage of 600 V and a continuous forward current of 8 A per diode. Key electrical characteristics include a maximum non-repetitive surge current of 200 A and a low forward voltage drop of 1.35 V at 8 A. Reverse leakage current is specified at 5 mA at the rated voltage. The component operates within a junction temperature range of -55°C to 175°C.

Diode Arrays Procurement Notes

Verify the specific suffix 'CTR' corresponds to the tape-and-reel packaging format required for your assembly line, as standard versions may differ in shipping configuration. Confirm that the isolated tab variant meets your thermal management and electrical isolation requirements compared to non-isolated alternatives. Ensure the TO-220AB footprint matches your PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material declarations before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with common anode topology is required for high-efficiency power stages. The 600V rating makes it suitable for mains-derived supplies or intermediate bus architectures. Consider the 8A continuous current capability against your thermal dissipation strategy. The through-hole TO-220AB package offers superior heat sinking compared to surface-mount options, making it ideal for applications where board space allows for larger components but thermal performance is critical.

Diode Arrays Part Context

This part belongs to the SDURF series of ultra-fast recovery and Schottky diode arrays from SMC Diode Solutions. It is designed for high-frequency switching applications where low reverse recovery charge and fast switching speeds are essential. The series typically includes various voltage and current ratings packaged in TO-220AB formats to support diverse industrial and consumer power supply designs.

Diode Arrays Replacement Considerations

Direct replacements must match the 600V/8A dual common-anode Schottky specification and TO-220AB isolated tab package. Verify equivalent forward voltage and reverse leakage characteristics to ensure circuit performance parity.
