HBS504-HF

Overview

The HBS504-HF is a single-phase surface-mount bridge rectifier manufactured by Comchip Technology. It features a glass passivated silicon chip construction housed in the HBS package. The device provides a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 5A at 25°C. Key electrical characteristics include a maximum RMS voltage of 280V, a maximum DC blocking voltage of 400V, and a peak non-repetitive surge current rating of 150A. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated die structure ensures high reliability and resistance to mechanical stress during operation.
• Low profile surface mount design optimizes board space utilization for compact electronic assemblies.
• High surge current capability protects circuitry against transient overcurrent events.

Applications

• General purpose AC to DC conversion in power supply units
• Battery charging circuits for consumer electronics
• DC power input stages in industrial control systems

Procurement Notes

Verify that the ordering part number includes the -HF suffix to confirm halogen-free compliance with RoHS directives. Ensure the procurement specification matches the HBS package outline dimensions to guarantee compatibility with existing PCB footprints. Confirm that the required reverse voltage rating of 400V aligns with the system's peak line voltage requirements before finalizing the purchase order.

Selection Notes

Select this component when a 5A continuous current capacity and 400V reverse voltage rating are required in a surface-mount form factor. The HBS package is suitable for applications where board space is limited compared to through-hole alternatives. Consider the thermal derating requirements if the operating ambient temperature exceeds standard conditions or if the load involves significant capacitive components requiring current reduction.

Part Context

Comchip Technology specializes in SMD discrete semiconductors, including bridge rectifiers, Schottky diodes, and TVS protectors. The company utilizes patented flat chip manufacturing processes and gold termination technologies to minimize tin whisker potential. This product line supports various industries such as automotive, lighting, and telecommunications, adhering to quality standards like ISO9001 and AEC-Q101 for high-reliability applications.

Replacement Considerations

Direct substitutes must match the 5A current rating, 400V reverse voltage, and HBS package footprint. Verify that alternative manufacturers offer glass passivated bridge rectifiers with equivalent surge current capabilities and junction temperature ranges to ensure functional parity without redesigning the PCB layout.
