RDBF38-13

Bridge Rectifier Overview

The RDBF38-13 is a single-phase bridge rectifier manufactured by Diodes Incorporated, utilizing silicon technology. It features an SMBF (DBF-4) surface-mount package with dimensions of 8.2 mm length, 6.85 mm width, and 1.5 mm height. The device supports a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 800 V. Key electrical characteristics include a maximum forward voltage drop of 1.3 V at rated current, a non-repetitive peak surge current capacity of 100 A, and a maximum reverse leakage current of 5 uA. It operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets or environmental files. Check for recent Product Change Notifications (PCNs) or End-of-Life (EOL) notices, as discontinuance notifications have been recorded for this part number. Ensure packaging specifications match project requirements before ordering.

Bridge Rectifier Selection Notes

Select the RDBF38-13 when a 3 A current rating and 800 V reverse voltage are required in a compact SMD footprint. Compare forward voltage drop and thermal resistance against alternatives if efficiency or heat dissipation is critical. Ensure the DBF-4 package dimensions fit the PCB layout constraints. Validate that the operating temperature range meets the specific application environment demands.
