42CTQ030-1

Diode Arrays Overview

The Vishay 42CTQ030-1 is a center tap Schottky rectifier module featuring two independent legs with a common cathode configuration. It utilizes proprietary barrier technology to achieve very low forward voltage drop and moderate leakage current. The device is designed for reliable operation up to a maximum junction temperature of 150 °C. Key electrical ratings include a maximum average forward current of 20 A per leg (40 A total) and a maximum repetitive peak reverse voltage of 30 V. The component is housed in a TO-262 package.

Diode Arrays Procurement Notes

Verify the specific ordering suffix to confirm the package style and packaging format. The -1 suffix indicates the TO-262 case style. Confirm lead-free status and reel orientation if applicable. Ensure the procurement documentation matches the required thermal resistance and mounting torque specifications for the selected application environment.

Diode Arrays Selection Notes

Select this component for applications requiring a center tap Schottky rectifier with a 30 V rating. The TO-262 package provides specific thermal characteristics distinct from the D2PAK variant. Evaluate the thermal resistance requirements against the heatsink interface. Consider the surge current capabilities and junction capacitance for high-frequency switching designs.

Diode Arrays Part Context

This part belongs to the Vishay High Power Products Schottky Rectifier series. It shares the same electrical ratings as the 42CTQ030S but differs in physical package. The 42CTQ030S uses a D2PAK case, while the 42CTQ030-1 utilizes a TO-262 case. Both variants offer identical performance metrics regarding current handling and voltage ratings.

Diode Arrays Replacement Considerations

The 42CTQ030S is a direct functional substitute with identical electrical parameters. Verify that the PCB footprint accommodates the TO-262 package dimensions instead of the D2PAK layout. Thermal management strategies must be adjusted to account for the different package geometry and mounting surface area.
