Overview
The NTSB40120CT-1G is a through-hole trench-based Schottky rectifier manufactured by onsemi. It features a dual common cathode configuration housed in an I2PAK package with four pins. The device supports a maximum continuous forward current of 40A and a peak reverse repetitive voltage of 120V. Key electrical parameters include a maximum forward voltage drop of 430mV and a peak non-repetitive forward surge current of 250A.
Feature Summary
- Utilizes trench technology to achieve very low forward voltage characteristics for improved efficiency.
- Integrates two independent diodes within a single common cathode assembly for compact circuit design.
Applications
- DC-DC converter circuits
- Free-wheeling rectification in power supplies
- Reverse polarity protection systems
Procurement Notes
Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required thermal management standards for the intended application environment. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when high current handling and low conduction losses are critical requirements. The I2PAK package provides robust mechanical stability and thermal dissipation capabilities suitable for high-power applications. Evaluate the 120V rating against system voltage peaks to ensure adequate safety margins during operation.
Part Context
This part belongs to the NTSB series of trench Schottky rectifiers from onsemi, designed for high-efficiency power conversion. The series emphasizes reduced forward voltage drops compared to standard junction diodes. The NTSB40120CT-1G specifically addresses applications requiring substantial current capacity with minimal heat generation.
Replacement Considerations
Consult official substitution guides for equivalent trench Schottky devices with matching current and voltage ratings. Verify pinout compatibility and thermal resistance values before implementing any alternative components in existing designs.
