15CTQ035

Overview

The 15CTQ035 is a Schottky rectifier diode array manufactured by SMC Diode Solutions. It features a center tap configuration with one pair of common cathodes, designed for through-hole mounting in TO-220AB packages. The device supports a maximum repetitive peak reverse voltage of 35 V and an average forward rectified current of 15 A at 25°C. Each internal diode handles 7.5 A. It operates with a maximum junction temperature of 150°C and exhibits a low forward voltage drop characteristic typical of Schottky technology.

Feature Summary

• Center tap configuration providing dual diodes with a common cathode connection
• Low forward voltage drop to enhance efficiency in power conversion applications
• High purity, high temperature epoxy encapsulation for robust thermal performance
• Capable of operation up to a maximum junction temperature of 150°C

Applications

• DC-to-DC converters
• Free-wheeling diodes in inductive load circuits
• Polarity protection circuits
• Power supply rectification

Procurement Notes

Verify the specific datasheet version directly with SMC Diode Solutions before ordering, as product specifications may be updated. Confirm that the TO-220AB package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the 150°C junction temperature limit during high-load operations to maintain reliability.

Selection Notes

Select this component when a common cathode Schottky arrangement is required for center-tapped transformer or inductor configurations. The 35V rating suits low-voltage DC systems where minimizing forward conduction losses is critical. Consider the 15A total current capacity relative to the thermal environment, as derating may be necessary above ambient temperatures exceeding 25°C.

Part Context

This part belongs to the 15CTQ series of Schottky rectifiers from SMC Diode Solutions. These devices are engineered for general-purpose rectification in medium-current applications. The series utilizes advanced Schottky barrier technology to provide faster switching speeds and lower heat generation compared to standard silicon PN-junction rectifiers, making them suitable for modern efficient power designs.

Replacement Considerations

The VS-15CTQ035-M3 from Vishay General Semiconductor is a documented substitute with identical electrical ratings and pinout configuration.
