GSMBR0540

Single Diodes Overview

The GSMBR0540 is a Schottky Barrier Diode manufactured by Good-Ark Semiconductor, housed in an SOD-123 surface-mount package. It features a maximum repetitive peak reverse voltage (VRRM) of 40 V and a mean rectifying current (IO) of 0.5 A. The device exhibits a low forward voltage with a maximum value of 0.55 V at 500 mA, and a maximum reverse current of 80 μA at 40 V. Thermal performance includes a junction-to-ambient thermal resistance of 244 °C/W, a power dissipation rating of 410 mW, and a junction temperature range from -55 °C to +150 °C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific part number suffix against the manufacturer's ordering information to ensure correct carrier quantity and tape & reel specifications. Confirm that the component meets RoHS compliance requirements and lead-free finish standards as documented in the official datasheet before integration into production workflows.

Single Diodes Selection Notes

Select this component when a 40 V reverse voltage rating and 0.5 A continuous current capacity are required in a compact SOD-123 footprint. Consider the low forward voltage drop for improved efficiency in low-voltage applications. Ensure the operating ambient temperature remains within the specified limits to maintain the rated power dissipation and thermal performance.

Single Diodes Part Context

The GSMBR0540 belongs to the GSMBR05x0 series of Schottky Barrier Diodes produced by Good-Ark Semiconductor. This family shares common electrical characteristics and physical packaging, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 20 V to 80 V. All variants utilize the same SOD-123 surface-mount package and share similar thermal and current handling capabilities.

Single Diodes Replacement Considerations

Compatible substitutes include other 40 V, 0.5 A Schottky diodes in the SOD-123 package, such as the MBR0540 from ON Semiconductor or Micro Commercial Components. Verify pinout compatibility, forward voltage characteristics, and reverse leakage current specifications to ensure functional equivalence in the target circuit design.
