NTST40100CTG

Overview

The NTST40100CTG is a dual common cathode Schottky rectifier manufactured by onsemi. It utilizes trench-based technology to achieve very low forward voltage characteristics, enhancing efficiency in power conversion applications. The device is rated for a maximum repetitive reverse voltage of 100V and offers a total average forward current of 40A. Designed for robust performance, it supports a maximum non-repetitive peak surge current of 320A. The component operates within a junction temperature range of -55°C to +175°C and is housed in a TO-263AB (D2PAK) package.

Feature Summary

• Trench-based Schottky technology ensures minimal forward voltage drop for improved energy efficiency.
• Dual common cathode configuration simplifies circuit design for synchronous rectification or OR-ing applications.
• High thermal stability allows reliable operation at elevated junction temperatures up to 175°C.

Applications

• DC-DC converters requiring high efficiency and low heat dissipation
• Power supply output rectification in industrial equipment
• Free-wheeling diodes in motor drive circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the selected variant meets the required automotive or industrial qualification standards if applicable to your system design. Cross-reference the date code and lot traceability requirements with your quality management protocols before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require low forward voltage loss at high currents. The 100V rating suits low-voltage DC bus applications. Consider the thermal resistance of the TO-263AB package and ensure adequate PCB copper area for heat sinking. Verify that the reverse leakage current specifications meet the standby power constraints of the target application.

Part Context

This part belongs to onsemi's NTS series of trench Schottky rectifiers. The series is engineered to replace standard PN-junction diodes in high-frequency switching applications where reduced conduction losses are critical. The dual configuration provides a compact solution for bridging or redundant power paths without increasing the component footprint significantly.

Replacement Considerations

Direct replacements include the NTST40100CT-1G variant, which shares identical electrical specifications and pinout. Other compatible parts from the same family may offer different packaging options but must be verified for equivalent current and voltage ratings.
