SBX2540-3G

Single Diodes Overview

The SBX2540-3G is a third-generation Schottky barrier rectifier diode manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 25 A and a repetitive peak reverse voltage (VRRM) of 40 V. The device exhibits a maximum forward voltage (VF) of less than 0.45 V at 5 A and 25°C, with a typical value of 0.25 V at 5 A and 125°C. Peak forward surge current (IFSM) reaches 290 A under half-sine-wave conditions. The component operates within a junction temperature range of -50°C to +150°C and utilizes a compact Ø 5.4 x 7.5 mm package.

Single Diodes Feature Summary

• Optimized trade-off between forward voltage and leakage current for enhanced efficiency
• Lowest thermal resistance from junction to lead (RthL) to minimize junction temperature
• Smaller physical package outline compared to the previous generation SBX2540

Single Diodes Applications

• Solar bypass diodes
• Polarity protection circuits
• Output rectification in DC/DC converters

Single Diodes Procurement Notes

Verify that the specific part number matches the required voltage rating and current capacity for your design. Confirm compliance requirements such as RoHS and REACH status directly with the manufacturer or authorized distributors. Ensure that ordering suffixes like -Q or -AQ are not present if automotive qualification is not needed. Check mechanical data for tape and reel availability versus ammo pack options.

Single Diodes Selection Notes

Select this component when high efficiency and low heat dissipation are critical due to its superior thermal characteristics. Consider the reduced package size for space-constrained designs compared to older generations. Evaluate the 40 V reverse voltage limit against system transients. Verify that the 25 A continuous current rating aligns with the thermal management capabilities of the final assembly.

Single Diodes Part Context

This device belongs to Diotec's third-generation Schottky Barrier Rectifier series, which includes variants with different voltage ratings such as the SBX2545-3G and SBX2560-3G. These components are designed for commercial and industrial grade applications requiring standard reliability levels. The series emphasizes improved thermal performance and smaller footprints over previous iterations.

Single Diodes Replacement Considerations

The datasheet indicates that the SBX2540-3G has a smaller package outline than the SBX2540. Designers replacing older SBX2540 units should verify footprint compatibility and ensure that the new thermal resistance values meet the cooling requirements of the application.
