Overview
The HDBLS104G C1G is a single-phase bridge rectifier from the Taiwan Semiconductor HDBLS101G series, rated for a repetitive peak reverse voltage of 400V and an average forward current of 1A. It utilizes a DBLS surface-mount package with four terminals. The device supports a peak forward surge current of 50A and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum forward voltage of 1.3V at 1A and a reverse recovery time of 50ns. Thermal resistance values are 15°C/W (junction-to-lead) and 40°C/W (junction-to-ambient).
Feature Summary
- High surge current capability suitable for demanding power applications.
- Reliable low-cost construction utilizing molded plastic technique.
- Moisture sensitivity level 1 compliant per J-STD-020 standards.
Applications
- Switching mode power supply (SMPS)
- Adapters
- Lighting application
Procurement Notes
Verify component authenticity by checking markings against official datasheet diagrams. Confirm AEC-Q101 qualification status via the 'H' suffix in the ordering code. Ensure packaging matches specified tape and reel quantities. Validate RoHS compliance and halogen-free status according to IEC 61249-2-21 requirements before integration.
Selection Notes
Select this component for designs requiring 400V blocking capability in a compact DBLS footprint. Consider thermal management given the 40°C/W junction-to-ambient resistance. Verify that the 50ns reverse recovery time meets circuit switching speed requirements. Ensure input surge currents remain below the 50A limit during transient conditions.
Part Context
This part belongs to the HDBLS101G–HDBLS107G series, which offers varying reverse voltage ratings from 50V to 1000V while maintaining consistent current and package specifications. The series provides high-efficient recovery characteristics optimized for modern power conversion topologies. The specific model fills the 400V segment of this standardized product line.
Replacement Considerations
Direct substitutes within the same series include HDBLS103G (200V) or HDBLS105G (600V), provided voltage margins accommodate the change. Cross-series replacements must match the DBLS package dimensions and 1A current rating. Verify equivalent reverse recovery times and thermal performance characteristics.
FAQ
What is the reverse recovery time for the HDBLS104G?
The typical reverse recovery time (trr) is 50ns when tested under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A.
Is the HDBLS104G qualified for automotive applications?
Yes, versions with the 'H' suffix in the ordering code, such as HDBLS104GH, are AEC-Q101 qualified.
What is the maximum operating junction temperature?
The maximum junction temperature (TJ MAX) is 150°C.
