Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS501-G is determined by the following critical parameters:

• Voltage Rating: Peak reverse voltage must be 50V or greater to maintain circuit protection margins
• Current Rating: Average rectified current must be 5A or greater to handle design load requirements
• Diode Type: Single-phase bridge rectifier configuration required
• Technology: Standard rectifier technology
• Mounting Type: Through-hole configuration for PCB compatibility
• Package Compatibility: Physical dimensions must accommodate RS5 or equivalent 4-SIP footprint

The GBJ6005-F qualifies as a direct substitute based on these parameters. It maintains the 50V voltage rating, exceeds the 5A current requirement at 6A, preserves single-phase bridge rectifier topology, and uses compatible through-hole mounting with a standard 4-SIP GBJ package footprint.

Parameter Comparison

Engineering Selection Recommendations

The GBJ6005-F is suitable as a substitute for the RS501-G based on the following criteria:

• Voltage Compatibility: Both parts maintain 50V peak reverse voltage rating, ensuring equivalent circuit protection
• Current Capability: The GBJ6005-F 6A rating exceeds the RS501-G 5A requirement, providing operational margin
• Active Product Status: The GBJ6005-F is actively manufactured by Diodes Incorporated, ensuring long-term availability and supply chain stability
• Regulatory Compliance: The GBJ6005-F holds ROHS3 compliance and REACH Unaffected status, meeting modern environmental and regulatory requirements
• Temperature Range: The GBJ6005-F extended operating range (-65°C ~ 150°C) provides broader thermal performance compared to the RS501-G (-55°C ~ 125°C)
• Leakage Characteristics: The GBJ6005-F demonstrates lower reverse leakage current (5 µA vs 10 µA), indicating improved device quality

Frequently Asked Questions (FAQ)

Q: Can the GBJ6005-F directly replace the RS501-G in existing designs?

A: Yes. Both parts share identical 50V peak reverse voltage and single-phase bridge rectifier topology. The GBJ6005-F 6A current rating exceeds the RS501-G 5A requirement. Through-hole mounting compatibility exists between the RS5 and GBJ package configurations for standard PCB layouts.

Q: What are the key differences between these parts?

A: The GBJ6005-F provides higher current capacity (6A vs 5A), lower reverse leakage current (5 µA vs 10 µA), extended operating temperature range (-65°C to 150°C vs -55°C to 125°C), and active product status with ROHS3 compliance. The RS501-G is obsolete.

Q: Are there package footprint considerations?

A: Both parts use 4-SIP through-hole packages. The RS501-G uses RS5 package designation while the GBJ6005-F uses GBJ designation. Standard 4-SIP footprints are mechanically compatible for PCB assembly.

Q: Does the GBJ6005-F meet current regulatory requirements?

A: Yes. The GBJ6005-F is ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards. The RS501-G status for these certifications is not specified.

Q: What is the reverse leakage current difference impact?

A: The GBJ6005-F exhibits lower reverse leakage (5 µA @ 50V vs 10 µA @ 50V), indicating superior device quality and reduced parasitic current in the reverse-biased state. This provides improved circuit performance characteristics.
