Substitute Part Grouping Explanation

Substitution of the MBRF20100 C0G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 20 A
• Technology: Schottky
• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack
• Operating Temperature - Junction: -55°C to 150°C

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Acceptable within component-level performance tolerances
• Current - Reverse Leakage @ Vr: Acceptable within component-level performance tolerances
• Product Status: Active status preferred for ongoing availability; discontinued status acceptable for legacy applications
• Compliance Certifications: ROHS3 compliance required; additional certifications (AEC-Q101) do not disqualify substitution

Substitute parts identified below meet all mandatory matching parameters and maintain electrical and mechanical compatibility with the original MBRF20100 C0G specification.

Engineering Selection Recommendations

MBRF20100 (SMC Diode Solutions)

This substitute part is electrically and mechanically equivalent to the MBRF20100 C0G. The SMC Diode Solutions variant demonstrates superior forward voltage performance (880 mV vs. 950 mV @ 20 A), resulting in lower power dissipation. Product status is active, ensuring long-term availability and supply chain continuity. ROHS3 compliance is maintained. Higher reverse leakage current (1 mA vs. 100 µA @ 100 V) remains within acceptable operational parameters for Schottky diode applications. Packaging includes isolated tab configuration, which may provide enhanced thermal management in certain mounting scenarios.

MBRF20100HC0G (Taiwan Semiconductor Corporation)

This substitute part is electrically and mechanically equivalent to the MBRF20100 C0G and maintains identical electrical characteristics. Product status is active, providing improved availability compared to the discontinued original part. ROHS3 compliance is maintained. This variant includes AEC-Q101 automotive qualification, indicating suitability for automotive-grade applications. Identical forward voltage (950 mV @ 20 A) and reverse leakage current (100 µA @ 100 V) specifications match the original part precisely.

Frequently Asked Questions (FAQ)

Q: Can the MBRF20100 (SMC Diode Solutions) be used as a direct replacement for the MBRF20100 C0G?

A: Yes. Both parts meet identical voltage (100 V), current (20 A), temperature range (-55°C to 150°C), and package specifications (TO-220-2 Full Pack, ITO-220AC). The SMC variant exhibits lower forward voltage (880 mV vs. 950 mV @ 20 A), which reduces power dissipation and represents an improvement in circuit performance.

Q: What is the significance of the higher reverse leakage current in the SMC Diode Solutions variant?

A: The SMC MBRF20100 exhibits 1 mA reverse leakage at 100 V, compared to 100 µA in the original part. This tenfold increase remains within acceptable parameters for Schottky diode technology and does not compromise circuit functionality in standard rectification applications.

Q: Is the MBRF20100HC0G suitable for automotive applications?

A: Yes. The MBRF20100HC0G carries AEC-Q101 automotive qualification, indicating compliance with automotive-grade reliability and performance standards. This variant is suitable for both general industrial and automotive applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. The MBRF20100 C0G, MBRF20100 (SMC Diode Solutions), and MBRF20100HC0G all meet ROHS3 compliance requirements.

Q: What is the difference between the TO-220-2 Full Pack and TO-220-2 Full Pack with Isolated Tab?

A: Both configurations use the TO-220-2 package footprint and are mechanically compatible. The isolated tab variant (SMC Diode Solutions) provides electrical isolation of the tab from the die, which may be beneficial in specific thermal management or circuit isolation scenarios. Standard full pack configuration (original and MBRF20100HC0G) integrates the tab with the die connection.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For general rectification with optimized power efficiency, the MBRF20100 (SMC Diode Solutions) is recommended due to lower forward voltage. For automotive applications or when matching original electrical characteristics precisely, the MBRF20100HC0G is recommended.

Q: Are there any moisture sensitivity concerns with these parts?

A: All three parts carry MSL (Moisture Sensitivity Level) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
