Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF20L100CT is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Mounting Type: Through Hole
• Speed: Fast Recovery ≤500 ns, >200 mA (Io)
• Operating Temperature Range: -55°C to 150°C minimum

Current Rating Considerations: Substitute parts are grouped into two categories based on average rectified current per diode:

1. Direct Equivalents (20 A Rating): Parts rated for 20 A average rectified current maintain identical current handling capacity to the main part.

2. Similar Parts (10 A or 30 A Rating): Parts with different current ratings are classified as similar substitutes. Parts rated at 10 A provide reduced current capacity and are suitable for applications with lower current requirements. Parts rated at 30 A provide increased current capacity for higher-demand applications.

All substitute parts maintain the 100 V reverse voltage rating, Schottky technology, common cathode configuration, TO-220-3 package, and fast recovery speed specifications. Compliance certifications (RoHS3, REACH status, ECCN, HTSUS codes) are provided for each part to support procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Current Rating - 20 A):

The following parts maintain the 20 A average rectified current rating and are suitable for direct substitution in applications requiring equivalent current handling:

• VF40100C-E3/4W (Vishay): Provides lower forward voltage (730 mV @ 20 A) compared to the main part (850 mV @ 20 A), with ROHS3 compliance and REACH Unaffected status. Operating temperature range not specified in provided data.

• VF40100C-M3/4W (Vishay): Identical electrical characteristics to VF40100C-E3/4W with specified operating temperature range of -40°C to 150°C, ROHS3 compliance, and REACH Unaffected status.

• VF60100C-M3/4W (Vishay): Rated for 30 A average rectified current, providing increased current capacity. Forward voltage of 790 mV @ 30 A. Operating temperature range -40°C to 150°C, ROHS3 compliant, REACH Unaffected.

Reduced Current Rating (10 A):

The following parts are rated for 10 A average rectified current and are suitable for applications with lower current requirements:

• MBRF20100CT-E3/4W (Vishay): Forward voltage 800 mV @ 10 A, operating temperature -65°C to 150°C (extended low-temperature range), ROHS3 compliant, REACH Unaffected.

• VF20100C-E3/4W (Vishay): Forward voltage 790 mV @ 10 A, operating temperature -40°C to 150°C, ROHS3 compliant, REACH Unaffected.

Alternative Manufacturers (20 A Rating):

• MBRF20100CT (MDD): 20 A rating, forward voltage 950 mV @ 10 A, ROHS3 compliant. Package specified as TO-220AB (not isolated tab variant).

• MBRF20100CTL (SMC Diode Solutions): Common cathode configuration, TO-220-3 Full Pack with isolated tab, ROHS3 compliant, REACH Affected status.

• MBRF20100CTP (SMC Diode Solutions): Common cathode configuration, TO-220-3 Full Pack with isolated tab, ROHS3 compliant, REACH Affected status.

• SBRF20100CT (SMC Diode Solutions): Common cathode configuration, TO-220-3 Full Pack with isolated tab, ROHS3 compliant, REACH Affected status.

All substitute parts maintain Schottky technology, fast recovery speed (≤500 ns), and 100 V reverse voltage rating. Selection should account for forward voltage characteristics, reverse leakage specifications, operating temperature requirements, and regulatory compliance status (REACH Affected vs. Unaffected) for the specific application.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the MBRF20L100CT?

A: The critical parameters are: 100 V DC reverse voltage rating, 1 Pair Common Cathode configuration, Schottky technology, TO-220-3 Full Pack with isolated tab package, through-hole mounting, fast recovery speed (≤500 ns), and operating temperature range of at least -55°C to 150°C. All substitute parts must meet these specifications.

Q: Can I use a 10 A rated part in place of the 20 A MBRF20L100CT?

A: Parts rated for 10 A average rectified current (MBRF20100CT-E3/4W and VF20100C-E3/4W) can be used only in applications where the actual current requirement does not exceed 10 A. These parts are not suitable for applications requiring the full 20 A capacity of the main part.

Q: Can I use a 30 A rated part in place of the 20 A MBRF20L100CT?

A: Yes. The VF60100C-M3/4W is rated for 30 A average rectified current and maintains all other critical parameters (100 V reverse voltage, common cathode configuration, TO-220-3 package, fast recovery speed). This part provides increased current capacity and is suitable for direct substitution.

Q: What is the difference between TO-220-3 Full Pack with isolated tab and TO-220AB packaging?

A: The TO-220-3 Full Pack with isolated tab provides electrical isolation between the mounting tab and the circuit, whereas TO-220AB does not specify isolated tab construction. For applications requiring tab isolation, only parts explicitly specified with "Isolated Tab" should be used.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant. However, some parts have REACH Affected status (MBRF20100CTL, MBRF20100CTP, SBRF20100CT) while others have REACH Unaffected status. Verify REACH compliance requirements for your specific application and region.

Q: How do forward voltage characteristics differ among substitute parts?

A: Forward voltage varies across substitute parts. The main part (MBRF20L100CT) specifies 850 mV @ 20 A. Vishay parts (VF40100C series) provide lower forward voltage at 730 mV @ 20 A, while SMC Diode Solutions parts range from 800 mV to 950 mV depending on the specific model and test current. Lower forward voltage reduces power dissipation in the application.

Q: What is the significance of reverse leakage current specifications?

A: Reverse leakage current indicates the small current that flows through the diode when reverse biased. The main part specifies 20 µA @ 100 V, while most substitute parts specify 1000 µA @ 100 V or 100 µA @ 100 V. Higher reverse leakage may affect circuit performance in sensitive applications requiring minimal leakage current.

Q: Can I substitute parts with different operating temperature ranges?

A: Operating temperature range substitution depends on your application requirements. The main part operates from -55°C to 150°C. Parts with narrower ranges (such as -40°C to 150°C) are suitable only if your application does not require operation below -40°C. Parts with extended low-temperature ranges (such as -65°C to 150°C) provide additional margin for low-temperature operation.

Q: What does "1 Pair Common Cathode" configuration mean?

A: This configuration contains two diodes with a shared cathode terminal. The three leads of the TO-220-3 package consist of two anodes and one common cathode. This configuration is suitable for bridge rectifier applications and dual-diode circuits where a common cathode connection is required.
