NTSB40120CTG

Overview

The NTSB40120CTG is a 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 of 430mV, a peak non-repetitive forward surge current of 250A, and a peak reverse current of 400μA. Operating temperatures range from -55°C to 175°C.

Feature Summary

• Trench-based Schottky technology for very low forward voltage
• Dual common cathode configuration for efficient power conversion
• High thermal stability suitable for demanding environments

Applications

• DC-DC converters
• Free-wheeling diodes
• Polarity protection circuits

Procurement Notes

Verify the specific suffix against official datasheets to confirm packaging and tape-and-reel specifications. Ensure the component meets required automotive or industrial standards if applicable. Cross-reference pinout and thermal resistance values with the manufacturer's latest documentation before integration.

Selection Notes

Select this component for applications requiring low forward voltage drop and high current handling at low reverse voltages. The dual common cathode design simplifies circuit topology compared to discrete single diodes. Evaluate thermal management requirements based on the I2PAK package capabilities and expected operating temperature range.

Part Context

This part belongs to onsemi’s NTSB series of trench-based Schottky rectifiers. These devices are designed to replace standard silicon rectifiers where lower forward voltage and improved efficiency are critical. The series offers various configurations including single, dual, and triple diodes in multiple packages.

Replacement Considerations

Direct substitutes include NTSB40120CT-1G and NTSB40120CTT4G. Verify that alternative parts match the 40A current rating, 120V voltage rating, and I2PAK package dimensions.
