NTSB40120CT-1G Description

Short technical summary and product information.

The NTSB40120CT-1G is a trench-based Schottky rectifier diode array from On Semiconductor, designed for high-efficiency power conversion. It contains two Schottky diodes in a common cathode configuration, each rated for 20A average rectified forward current (40A per device) with a maximum DC blocking voltage of 120V. The device features exceptionally low forward voltage, typically 0.43V at 5A and 125°C, which reduces power loss and improves thermal performance.

 

This diode array is suitable for switching power supplies, DC-DC converters, freewheeling and OR-ing diodes, and reverse battery protection. It offers fast switching with exceptional temperature stability and high surge capability (250A non-repetitive peak surge current). The maximum junction-to-case thermal resistance is 1.3°C/W per diode, aiding heat dissipation.

 

The NTSB40120CT-1G is housed in a through-hole I2PAK (TO-262) package with long leads, making it suitable for high-current PCB mounting. The operating temperature range is -40°C to 150°C. The device is RoHS3 compliant and has an MSL of 1 (unlimited).
