NTSV20U80CTG

Overview

The NTSV20U80CTG is a trench-based Schottky rectifier manufactured by onsemi, designed for high-efficiency power conversion. It features a dual common cathode configuration housed in a TO-220-3 through-hole package. Key electrical specifications include a maximum repetitive reverse voltage of 80 V and a continuous forward current rating of 20 A. The device exhibits a low typical forward voltage of 1.18 V at rated current, minimizing conduction losses. It supports a non-repetitive peak surge current of 60 A and operates within a junction temperature range of -40°C to +150°C.

Feature Summary

• Trench-based Schottky technology ensures very low forward voltage for enhanced efficiency
• Dual common cathode configuration allows flexible circuit integration
• Robust thermal performance with extended operating temperature range up to 150°C

Applications

• DC-DC converters
• Free-wheeling diodes in synchronous rectification circuits
• Polarity protection applications

Procurement Notes

Verify the specific suffix 'CTG' corresponds to tube packaging when sourcing components. Confirm that the procurement channel accepts end-of-life or obsolete status if applicable, as availability may be limited compared to active production parts. Ensure the receiving facility handles through-hole packages appropriately for assembly processes.

Selection Notes

Select this component for designs requiring low forward voltage drop at moderate current levels up to 20 A. The 80 V rating suits low-voltage DC systems. Consider the TO-220-3 package for board-level mounting where thermal dissipation via the lead frame is sufficient. Evaluate thermal resistance requirements against the expected ambient conditions and heat sinking capabilities.

Part Context

This part belongs to onsemi's NTSV series of Trench Schottky Rectifiers. These devices are engineered to replace standard PN junction rectifiers, offering superior switching characteristics and reduced power loss. The series targets applications demanding high efficiency and reliability in compact power supply architectures.

Replacement Considerations

Direct substitutes must match the 80 V reverse voltage, 20 A current rating, and TO-220-3 package. Verify equivalent forward voltage and reverse leakage specifications to ensure performance parity. Check manufacturer obsolescence notices for alternative recommended parts.
