Overview
The NTSV20120CTG is a dual common cathode Schottky power rectifier manufactured by onsemi. It features a silicon construction housed in a TO-220-3 through-hole package. The device supports a maximum continuous forward current of 20 A and a repetitive peak reverse voltage of 120 V. Key electrical characteristics include a maximum forward voltage of 1.18 V at rated current, a peak non-repetitive forward surge current capability of 40 A, and a maximum reverse leakage current of 500 uA. It operates within a temperature range of -40°C to +150°C junction temperature.
Feature Summary
- Dual common cathode configuration for efficient bridge or center-tapped applications
- Schottky barrier technology for low forward voltage drop and high efficiency
- Robust thermal performance with high surge current handling capability
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in inductive load circuits
- Power supply input rectification stages
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance during procurement. Confirm the package type matches the design requirements as it utilizes a TO-220-3 leaded format. Ensure the supplier provides official datasheets to validate the 20 A and 120 V ratings against the actual component markings before integration into production systems.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency. The dual common cathode arrangement simplifies circuit layout compared to discrete single diodes. Ensure the operating environment stays within the specified -40°C to +150°C junction temperature range to maintain reliability and prevent premature failure due to thermal stress.
Part Context
This part belongs to onsemi's NTSV series of Schottky rectifiers, designed for general-purpose power conversion. It complements other devices in the lineup offering similar voltage and current ratings but with different packaging options. The series focuses on providing reliable rectification solutions for industrial and consumer electronics power supplies requiring moderate current handling.
Replacement Considerations
Direct replacements must match the 20 A current rating, 120 V voltage rating, and TO-220-3 package. Verify that substitute parts maintain equivalent forward voltage and reverse leakage specifications to ensure circuit performance parity.
