Procurement Notes

Verify the specific suffix 'T4G' to confirm tape and reel packaging and lead-free compliance. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design. Cross-reference the datasheet revision date to confirm technical specifications remain consistent with current production standards.

Selection Notes

Select this component when a dual Schottky rectifier with a 100V blocking capability and 30A continuous current rating is required. The D2PAK package is suitable for applications needing robust thermal dissipation through the exposed tab. Consider the low forward voltage characteristic for improved efficiency in low-voltage, high-current output stages compared to standard PN junction rectifiers.

Part Context

This device belongs to onsemi's NTSB series of ultra-fast trench Schottky rectifiers. The series is engineered to replace traditional silicon rectifiers in applications demanding higher efficiency and faster switching speeds. The common cathode arrangement integrates two independent diodes into a single compact package, reducing board space and simplifying assembly processes.

Replacement Considerations

Direct replacements must match the 100V Vrrm, 30A If, and TO-263/D2PAK-3 package outline. Verify that substitute components maintain comparable forward voltage and reverse leakage specifications to ensure system performance parity.
