Overview
The NTST20120CTG is a dual Schottky rectifier manufactured by onsemi, featuring a common cathode configuration within a TO-220-3 package. It supports a continuous forward current of 20 A and a repetitive reverse voltage rating of 120 V. The device utilizes silicon technology with a maximum forward voltage of 1.18 V at rated current. It withstands a forward surge current of 40 A and exhibits a reverse leakage current of 500 uA. Operating temperatures range from -40°C to +150°C junction temperature.
Feature Summary
- Dual common cathode topology for efficient power conversion
- Trench Schottky technology for low forward voltage drop
- High thermal stability up to 150°C junction temperature
Applications
- DC-DC converters
- Free-wheeling diodes in inductive loads
- Power supply output rectification
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the TO-220-3 package dimensions match the target PCB footprint requirements. Ensure the operating environment does not exceed the specified 150°C junction temperature limit under full load conditions.
Selection Notes
Select this component when a dual common cathode Schottky rectifier is required for 120 V applications. The 20 A current rating suits moderate power levels where low forward voltage is critical for efficiency. Compare thermal resistance values against available heatsinking options to ensure reliable operation within the specified temperature range.
Part Context
This part belongs to onsemi's NTS series of Trench Schottky Rectifiers. The series is designed to offer improved switching efficiency through reduced forward voltage and leakage current compared to standard planar technologies. It complements other variants in the family offering different current and voltage ratings.
Replacement Considerations
Check for direct pin-compatible substitutes such as the NTSV30120CTG if higher current capacity is acceptable. Verify electrical parameters against alternative manufacturers' offerings to ensure compatibility with existing circuit designs.
