NTSB40100CTT4G

Overview

The NTSB40100CTT4G is a dual Schottky rectifier manufactured by onsemi, featuring a common cathode configuration. It utilizes trench technology to achieve low forward voltage drop while maintaining stable switching characteristics across a wide temperature range. The device is housed in a D2PAK (TO-263-3) surface-mount package and is rated for a maximum repetitive reverse voltage of 100V with a continuous forward current capacity of 20A per anode.

Feature Summary

• Employs trench Schottky technology to minimize forward voltage drop without the high reverse leakage typical of planar devices.
• Provides stable switching performance over a wide operating temperature range.
• Features a common cathode dual anode configuration suitable for synchronous rectification.

Applications

• Output rectification in switch-mode power supplies
• Rectification in laptop adapters
• ATX power supply units
• Flat panel display power circuits

Procurement Notes

Verify the specific suffix T4G confirms tape-and-reel packaging when sourcing. Confirm the manufacturer is onsemi, formerly ON Semiconductor, to ensure component authenticity. Cross-reference the datasheet for thermal resistance values relevant to your PCB layout. Ensure the D2PAK footprint matches your design requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring efficient rectification with minimal conduction losses. The 100V rating suits low-voltage DC-DC converters. Consider the thermal performance of the D2PAK package for heat dissipation needs. Compare against planar Schottky alternatives if reverse leakage is a critical constraint in your specific circuit design.

Part Context

This part belongs to the NTST/NTSB series of trench Schottky rectifiers from onsemi. These devices are designed to replace traditional planar Schottky diodes where lower forward voltage and better thermal stability are required. The series is widely used in consumer electronics and industrial power supplies.

Replacement Considerations

Check for direct pin-compatible substitutes within the same voltage and current ratings. Verify that any replacement maintains the trench technology benefits regarding reverse leakage and forward voltage characteristics. Ensure the alternative package matches the D2PAK form factor for board compatibility.
