GSXD080A004S1-D3

Overview

The SemiQ GSXD080A004S1-D3 is a Schottky rectifier diode module designed for high-current power conversion applications. It features a maximum repetitive reverse voltage of 45V and an average forward current rating of 80A. The device utilizes a SOT-227 (Minibloc) four-terminal package, facilitating robust base mounting for efficient thermal dissipation. Key electrical characteristics include a maximum forward voltage drop of 750mV at the rated current and a reverse leakage current of 1mA at the peak reverse voltage. The component operates within a junction temperature range of -40°C to +150°C.

Feature Summary

• Schottky barrier technology ensures fast switching speeds with minimal reverse recovery charge.
• High current density design supports 80A continuous operation in a compact footprint.
• Low forward voltage drop minimizes conduction losses during high-load conditions.
• Robust Minibloc packaging provides reliable thermal management for base-mount installations.

Applications

• Output rectification in DC-DC converters
• Freewheeling diodes in synchronous buck circuits
• Power supply units requiring low-loss rectification

Procurement Notes

Verify the specific suffix 'D3' against the manufacturer's latest datasheet to confirm compliance with current environmental standards and material composition. Confirm that the SOT-227 pinout matches the target PCB layout, as terminal configurations can vary between manufacturers. Ensure the selected variant meets the required voltage and current derating curves for the intended operating temperature range.

Selection Notes

Select this component when designing systems requiring low forward voltage drops at high currents, such as 80A loads. The 45V reverse voltage rating suits low-voltage output stages. Consider the SOT-227 package constraints for board space and thermal pad requirements. Evaluate the trade-off between the 750mV forward voltage and system efficiency compared to alternative Schottky technologies.

Part Context

This part belongs to the SemiQ discrete diode portfolio, which focuses on silicon Schottky rectifiers for power electronics. The GSXD series typically targets industrial and consumer power supplies where efficiency and reliability are critical. SemiQ manufactures these components using specialized processes to optimize the balance between forward voltage and reverse leakage characteristics.

Replacement Considerations

Publicly confirmed substitute part numbers for GSXD080A004S1-D3 were not identified in available documentation. Verify compatibility with potential alternatives by matching the 80A current rating, 45V voltage rating, SOT-227 package dimensions, and thermal performance specifications.
