Overview
The NTSB40200CTG is a dual Schottky rectifier featuring a 200 V reverse voltage rating and a combined maximum average forward current of 40 A. It utilizes trench-based technology to achieve a low forward voltage of 840 mV at rated conditions. The device supports a peak non-repetitive forward surge current of 250 A and operates within a temperature range of -55 °C to +150 °C. Packaged in a TO-263-3 (D2PAK) surface-mount configuration, it integrates two common cathode diodes in a single unit.
Feature Summary
- Dual common cathode configuration for space-efficient integration
- Trench-based technology enabling very low forward voltage drop
- High thermal stability with extended operating temperature range
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in switching power supplies
- Reverse polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS and REACH directives by checking the Material Composition Declaration. Confirm that the requested variant matches the required thermal and electrical ratings for the target application environment.
Selection Notes
Select this component when high current handling and low conduction losses are critical. The dual common cathode design simplifies layout compared to discrete solutions. Evaluate thermal management requirements due to the high current capacity. Consider the TO-263-3 package for adequate heat dissipation in surface-mount applications.
Part Context
This part belongs to onsemi's NTSB series of trench Schottky rectifiers. These devices are designed for high-efficiency power conversion applications requiring robust performance. The series emphasizes reduced forward voltage to minimize power loss and improve overall system efficiency in modern power supply designs.
Replacement Considerations
Cross-reference with other dual Schottky rectifiers offering similar 200 V and 40 A ratings. Verify pinout compatibility and thermal resistance values before substitution. Ensure the alternative device meets the same junction temperature and surge current specifications.
