Overview
The NTSV20120CTG is a dual Schottky power rectifier manufactured by onsemi, which acquired Fairchild Semiconductor. It features a common cathode configuration with a maximum average forward current of 20 A and a repetitive peak reverse voltage of 120 V. The device utilizes silicon technology and is housed in a TO-220-3 through-hole package. Key electrical characteristics include a maximum forward voltage of 1.18 V at rated current and a maximum non-repetitive peak forward surge current of 40 A. The component supports an operating junction temperature range from -40°C to +150°C.
Feature Summary
- Dual Schottky barrier rectification with common cathode topology
- Low forward voltage drop for improved efficiency
- High thermal stability suitable for demanding environments
Applications
- DC-DC converters
- Free-wheeling diodes in power supplies
- General purpose rectification
Procurement Notes
Verify the manufacturer status carefully as onsemi has discontinued this specific part number. Confirm availability through authorized distributors or secondary market suppliers. Ensure the replacement component matches the original electrical ratings and physical footprint requirements for your design.
Selection Notes
Select this component when a dual Schottky rectifier with a 20 A rating and 120 V blocking capability is required. The TO-220-3 package provides robust mounting options for high-current applications. Consider the low forward voltage characteristic for minimizing conduction losses in efficient power conversion circuits.
Part Context
This component belongs to the NTSV series of Schottky rectifiers produced by onsemi following its acquisition of Fairchild Semiconductor. The series is designed for general-purpose rectification applications requiring high reliability and low forward voltage characteristics. The TO-220-3 package is standard for through-hole mounting in various power electronics designs.
Replacement Considerations
The datasheet indicates this part is obsolete. Verify equivalent parts such as the NTSV30120CTG for higher current capacity or other dual Schottky rectifiers with matching 20A/120V ratings and TO-220-3 packaging.
