HDBLS101G

Overview

The HDBLS101G is a 1A, 50V high-efficient bridge rectifier from the Taiwan Semiconductor HDBLS series. It utilizes glass passivation and molded plastic construction in a DBLS surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage (VRRM) of 50V, an average forward current (IF) of 1A, and a peak forward surge current (IFSM) of 50A. The device features a typical reverse recovery time (trr) of 50ns and a junction temperature range of -55°C to +150°C. Electrical specifications also specify a maximum forward voltage of 1.0V at 1A and a maximum reverse current of 5µA at 25°C.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• High surge current capability with low thermal resistance
• RoHS compliant and halogen-free construction

Applications

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

Procurement Notes

Verify the specific suffix when ordering. The standard HDBLS1xG designation indicates general commercial grade availability. The 'H' suffix, as seen in HDBLS1xGH, explicitly denotes AEC-Q101 qualification. Confirm the required qualification level matches the application requirements before procurement to ensure compliance with automotive or industrial standards.

Selection Notes

Select the HDBLS101G for circuits requiring a 50V blocking voltage and 1A continuous current in a compact surface-mount form factor. Consider higher voltage variants within the HDBLS10xG series if system voltages exceed 50V. Evaluate the 50ns reverse recovery time suitability for high-frequency switching applications compared to standard rectifiers.

Part Context

This component belongs to the HDBLS series of high-efficiency bridge rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50V to 1000V across models HDBLS101G through HDBLS107G. All variants share the same DBLS package and 1A current rating, differing primarily in their reverse voltage capabilities and associated thermal characteristics.

Replacement Considerations

Direct substitutes include other 1A, 50V surface-mount bridge rectifiers in the DBLS package. Verify that replacement parts meet the 50ns reverse recovery time requirement and maintain equivalent thermal resistance values for reliable operation in existing PCB layouts.
