NTSJ3080CTG

Overview

The NTSJ3080CTG is a dual common cathode trench-based Schottky rectifier from onsemi, rated for 80 V reverse voltage and 15 A average forward current per diode. It utilizes fine lithography technology to achieve exceptionally low forward voltage (0.455 V typ at 5 A) and low leakage current. The device operates within a junction temperature range of -40°C to +150°C and features a TO-220FP package with a thermal resistance of 4.0 °C/W junction-to-case.

Feature Summary

• Fine Lithography Trench-based Schottky Technology for very low forward voltage and low leakage
• Fast switching with exceptional temperature stability
• Low power loss and lower operating temperature
• High surge capability

Applications

• Switching Power Supplies including Notebook/Netbook Adapters, ATX and Flat Panel Display
• High Frequency and DC-DC Converters
• Freewheeling and OR-ing diodes

• Instrumentation

Procurement Notes

Verify the specific ordering suffix 'G' confirms the Pb-Free package status as documented in the datasheet. Ensure the procurement matches the TO-220FP mechanical dimensions and lead solderability requirements specified by the manufacturer. Confirm compliance with UL 94-0 flammability ratings for the epoxy molding compound before final integration.

Selection Notes

Select this component for designs requiring high efficiency and low thermal dissipation in medium-current applications. The dual common cathode configuration simplifies circuit topology for freewheeling or OR-ing functions. Evaluate the 80 V rating against system peak reverse voltages to ensure adequate margin under transient conditions.

FAQ

What is the maximum nonrepetitive peak surge current?

The maximum nonrepetitive peak surge current is 160 A, applied at rated load conditions with a half-wave, single phase, 60 Hz surge.

How does the forward voltage change with temperature?

The typical instantaneous forward voltage decreases as temperature increases; for example, it drops from 0.516 V at 25°C to 0.455 V at 125°C at an IF of 5 A.

What is the junction-to-case thermal resistance?

The maximum thermal resistance from junction to case is 4.0 °C/W when insertion mounted to a 1 oz FR4 board.
