DBLS205G C1G

Bridge Rectifier Overview

The DBLS205G C1G is a single-phase bridge rectifier from the DBLS20xG series by Taiwan Semiconductor. It features a 600V repetitive peak reverse voltage and supports an average forward current of 2A. The device utilizes a DBLS surface-mount package with solder pad termination, measuring 10.3mm in length, 8.51mm in width, and 2.6mm in height. Electrical characteristics include a maximum forward voltage of 1.15V at 2A and a typical reverse leakage current of 2µA at rated voltage. It operates within a junction temperature range of -55°C to +150°C and withstands a peak forward surge current of 50A.

Bridge Rectifier Feature Summary

• Complies with RoHS standards and is halogen-free according to IEC 61249-2-21.
• Moisture sensitivity level is classified as Level 1 per J-STD-020.

Bridge Rectifier Applications

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

Bridge Rectifier Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging type and qualification status. The standard DBLS2xG designation indicates tape and reel packing. Confirm AEC-Q101 automotive qualification requirements if applicable, as this typically requires an 'H' suffix in the part number. Always cross-reference the manufacturer's latest datasheet version for any updates to mechanical or electrical specifications before finalizing procurement.

Bridge Rectifier Selection Notes

Select the DBLS205G variant specifically for circuits requiring a 600V blocking voltage rating. Ensure the design accommodates the 2A continuous forward current limit and the 50A non-repetitive surge current capability. Verify that the PCB layout matches the suggested pad dimensions for the DBLS package to ensure proper thermal dissipation and mechanical stability during soldering processes.

Bridge Rectifier Part Context

This component belongs to the DBLS201G through DBLS209G series, which covers voltage ratings from 50V to 1400V. All members share identical physical dimensions and thermal characteristics, differing only in their peak reverse voltage capabilities. The DBLS205G specifically fills the 600V segment of this standardized surface-mount bridge rectifier family.

Bridge Rectifier Replacement Considerations

Direct pin-compatible replacements within the same series include DBLS204G (400V) or DBLS206G (800V), provided the voltage rating meets or exceeds the circuit requirements. Other manufacturers offering similar 2A, 600V surface-mount bridge rectifiers in the DBLS package may be considered after verifying thermal resistance and forward voltage parameters.

Bridge Rectifier FAQ

What is the maximum junction temperature for the DBLS205G?

The maximum operating junction temperature (TJ MAX) is +150°C.

Does the standard DBLS205G part number indicate AEC-Q101 qualification?

No, the standard designation does not imply automotive qualification. An 'H' suffix (e.g., DBLS205GH) is required for AEC-Q101 qualified versions.

What is the typical junction-to-ambient thermal resistance?

The typical junction-to-ambient thermal resistance (RθJA) is 40°C/W.
