RH04-T

Bridge Rectifier Overview

The RH04-T is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It features a MiniDIP surface-mount package with bright tin-plated leads. The device supports a peak repetitive reverse voltage of 400 V and an average forward rectified current of 0.5 A at +40°C ambient temperature. Maximum instantaneous voltage drop is 1.15 V at 0.4 A, while peak reverse current reaches 5 µA at rated DC blocking voltage. Non-repetitive peak forward surge current capability is 30 A for an 8.3 ms half-sine wave. Operating and storage temperatures range from -55°C to +150°C.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable electrical characteristics and long-term reliability under varying thermal conditions.
• Miniature MiniDIP package design facilitates automated assembly processes and optimizes printed circuit board space utilization.
• Lead-free finish complies with RoHS directives, supporting environmentally conscious manufacturing standards.

Bridge Rectifier Applications

• General-purpose AC-to-DC conversion in low-power consumer electronics
• Power supply circuits requiring compact surface-mount rectification
• Automotive electronic modules compatible with specific change control requirements

Bridge Rectifier Procurement Notes

Verify the exact ordering part number RH04-T against the manufacturer's official documentation before procurement. Confirm that the MiniDIP package dimensions align with the target PCB footprint layout. Ensure compliance with relevant environmental directives such as RoHS if required by the end application. Check for any specific automotive qualification requirements if the component is intended for use in regulated vehicle systems.

Bridge Rectifier Selection Notes

Select the RH04-T when a 400 V reverse voltage rating and 0.5 A continuous current capacity are sufficient for the circuit design. Consider the 150 ns maximum reverse recovery time for standard frequency applications rather than high-speed switching environments. Evaluate the thermal resistance of 85 °C/W to ensure adequate heat dissipation within the specified operating temperature range without additional cooling measures.

Bridge Rectifier Part Context

The RH04-T belongs to the RH02-RH06 series of surface-mount standard recovery bridge rectifiers produced by Diodes Incorporated. This family shares identical physical packaging and general performance characteristics, differentiated primarily by their peak repetitive reverse voltage ratings. The RH04-T specifically addresses designs requiring a 400 V blocking capability within a compact form factor suitable for modern automated manufacturing lines.

Bridge Rectifier Replacement Considerations

Direct replacements within the same series include the RH02-T (200 V) and RH06-T (600 V), provided the voltage ratings match the circuit requirements. Verify that substitute components maintain the same MiniDIP package outline and pin configuration to ensure mechanical compatibility on existing PCB layouts.

Bridge Rectifier FAQ

What is the maximum non-repetitive peak forward surge current?

The RH04-T can withstand a non-repetitive peak forward surge current of 30 A for an 8.3 ms single half-sine wave superimposed on the rated load.

How does the device handle capacitive loads?

When used with capacitive loads, the average forward rectified current must be derated by 20% to maintain safe operating conditions.

Is the RH04-T suitable for automotive applications?

Standard RH04-T units are not automatically qualified for automotive use. For applications requiring AEC-Q100/101/104/200 qualification and IATF 16949 manufacturing, customers must contact Diodes Incorporated directly.
