GSXD120A008S1-D3

Overview

The SemiQ GSXD120A008S1-D3 is a high-current Schottky diode module rated for an average forward current of 240 A per package at a case temperature of 110 °C. It features a maximum repetitive peak reverse voltage of 80 V and a maximum RMS voltage of 56 V. The device provides a peak forward surge current capability of 1500 A for an 8.3 ms half-sine pulse. Electrical characteristics include a maximum instantaneous forward voltage of 0.73 V at 120 A and 125 °C, or 0.84 V at 25 °C. The junction-to-case thermal resistance is specified at 0.38 °C/W per leg.

Feature Summary

• Electrically isolated base plate design for secure mounting
• High surge current handling capability for transient protection
• Low forward voltage drop to minimize conduction losses
• Robust construction supporting high-temperature operation

• High-power DC-DC converter modules
• Industrial motor drive rectification stages
• Uninterruptible power supply (UPS) systems
• Solar inverter output rectification

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct voltage and current ratings. Confirm RoHS compliance status with the manufacturer prior to finalizing orders. Check for any recent revision history updates that may affect mechanical dimensions or electrical parameters. Ensure thermal management solutions align with the specified junction-to-case thermal resistance values.

Selection Notes

Select this component when applications require high current density in a compact footprint. Evaluate the thermal environment to ensure the case temperature remains within limits for the 240 A rating. Consider the 80 V blocking voltage margin relative to system transients. Verify isolation requirements match the 2500 V AC specification if galvanic separation is critical.

Part Context

This module belongs to the SemiQ GSXD series of Schottky diodes designed for high-efficiency power conversion. The series utilizes silicon carbide or advanced silicon technologies to achieve low forward voltage drops. The SOT-227 style packaging facilitates screw-mount installation on heatsinks. This specific part number represents a variant optimized for 80 V applications within the broader product family.

Replacement Considerations

Cross-reference with other SemiQ GSXD variants sharing identical pinouts and thermal characteristics. Verify that substitute components meet or exceed the 240 A continuous current and 1500 A surge ratings. Ensure replacement parts maintain the same isolation voltage and package dimensions for direct board compatibility.
