GSXD050A018S1-D3

Overview

The GSXD050A018S1-D3 is a Schottky diode array manufactured by SemiQ, designed for high-efficiency power conversion applications. It features two independent diodes housed in a SOT-227 (miniBLOC) chassis mount package. The device supports a maximum reverse voltage of 180V and handles a continuous forward current of 50A per diode. Key electrical characteristics include a forward voltage of 920mV at 50A and a reverse leakage current of 3mA at 180V. The junction temperature range spans from -40°C to 150°C, ensuring reliable operation under demanding thermal conditions.

Feature Summary

• Dual independent Schottky diode configuration within a single module
• Chassis mount design optimized for efficient heat dissipation
• High-speed switching capability inherent to Schottky technology

Applications

• DC-DC converter modules
• Free-wheeling rectification in motor drives
• Power supply output rectification

Procurement Notes

Verify the specific suffix D3 against official SemiQ documentation to confirm pinout and marking variations. Ensure thermal interface materials are compatible with the SOT-227 base plate. Confirm that the 180V rating aligns with the peak inverse voltage requirements of the target circuit topology. Validate mounting torque specifications to prevent mechanical stress on the ceramic substrate during assembly.

Selection Notes

Select this component when a dual-diode solution is required for synchronous or asynchronous rectification circuits operating below 180V. The miniBLOC package offers superior thermal performance compared to standard surface-mount options. Consider the 920mV forward voltage drop impact on overall system efficiency at full load currents. Evaluate the 3mA leakage current tolerance for low-power standby modes.

Part Context

This part belongs to SemiQ's discrete Schottky diode array lineup, utilizing silicon carbide or specialized silicon processes depending on the specific generation. The GSXD series is engineered for industrial and automotive power electronics where reliability and thermal management are critical. It complements other SemiQ products like the GCMX series MOSFETs in complete power stage designs.

Replacement Considerations

Direct substitutes must match the 180V/50A rating and SOT-227 footprint. Check datasheets for equivalent parts from manufacturers offering similar miniBLOC packages. Verify that alternative components maintain comparable forward voltage and reverse leakage characteristics to ensure circuit performance parity.
