NTSB30100CT-1G

Overview

The NTSB30100CT-1G is a dual Schottky rectifier manufactured by onsemi, featuring two independent 30A channels within a single package. It utilizes a 100V voltage rating and employs trench technology to achieve low forward voltage characteristics. The device is housed in a TO-263 (D²PAK) surface-mount package with an integrated thermal tab for efficient heat dissipation. This configuration supports high-efficiency power conversion requirements.

Feature Summary

• Dual channel architecture providing two independent rectification paths
• Trench Schottky technology ensures low forward voltage drop
• Integrated thermal tab design facilitates effective heat management

Applications

• Output rectification in switching power supplies
• Power circuits for laptop adapters
• Rectification stages in ATX computer power supplies

Procurement Notes

Verify the specific suffix against official documentation, as the provided model includes a '-1G' designation which may indicate a specific tape-and-reel variant or packaging option distinct from standard configurations. Confirm RoHS compliance status and halogen-free attributes directly with the manufacturer's current datasheet to ensure alignment with project regulatory requirements.

Selection Notes

Select this component when designing systems requiring dual isolated outputs or synchronous rectification alternatives with moderate voltage ratings. The TO-263 package is suitable for applications where board space is constrained but adequate thermal conductivity is necessary. Ensure the circuit design accounts for the reverse leakage characteristics typical of Schottky devices at elevated temperatures.

Part Context

This component belongs to onsemi's NTST series of trench Schottky rectifiers. The series is engineered to replace traditional planar Schottky diodes by offering superior performance metrics. The dual-channel format allows designers to reduce component count and simplify PCB layout in multi-rail power distribution architectures.

Replacement Considerations

Consult official substitution lists for equivalents such as the NTST30100CTG. Verify that any substitute maintains identical pinout compatibility and thermal resistance specifications to ensure seamless integration without redesigning the host circuit board.
