D2SB40

Bridge Rectifier Overview

The D2SB40 is a single-phase silicon bridge rectifier from the Taiwan Semiconductor D2SB series, rated for a maximum average forward current of 2 A and a repetitive peak reverse voltage of 400 V. The device utilizes a GBL plastic package with four isolated terminals and features a maximum non-repetitive peak forward surge current of 80 A. It operates within a junction temperature range of -55 °C to +150 °C, with a typical forward voltage drop of 1.1 V at full load. The component meets UL recognition standards and complies with RoHS directives.

Bridge Rectifier Feature Summary

• Glass passivated chip junction design for enhanced reliability
• High case dielectric strength suitable for PCB mounting
• High surge current capability with 80 A rating

Bridge Rectifier Applications

• Switching mode power supplies (SMPS)
• Power adapters
• Lighting applications

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix when purchasing. The standard D2SB40 designation indicates general-purpose availability in tube packaging. If automotive-grade qualification is required, confirm the presence of the 'H' suffix, which denotes AEC-Q101 certification. Ensure the procurement documentation matches the exact voltage and current ratings specified for the target circuit design.

Bridge Rectifier Selection Notes

Select the D2SB40 for circuits requiring a 400 V reverse blocking capability and 2 A continuous conduction. Consider the thermal resistance values if operating near maximum ambient temperatures. Verify that the GBL package dimensions fit the available board space. For high-vibration environments, ensure adequate mechanical securing due to the through-hole lead configuration.

Bridge Rectifier Part Context

This component belongs to the D2SB05–D2SB80 family of standard bridge rectifiers manufactured by Taiwan Semiconductor. The series covers reverse voltages from 50 V to 800 V while maintaining a consistent 2 A forward current rating across all variants. The D2SB40 specifically addresses mid-range voltage requirements within this standardized product line.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 2 A current rating, 400 V reverse voltage, and GBL package footprint. Verify that substitute components offer equivalent surge current capabilities and thermal performance characteristics to ensure circuit compatibility.
