Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF20100CTH is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io) (per Diode): 10 A
• Operating Temperature - Junction: -65°C ~ 175°C
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack

Direct Equivalent: MBRF20100CTG meets all primary substitution criteria with identical electrical specifications and packaging. This part is manufactured by onsemi and maintains Active product status.

Similar Substitute: MBRF20H100CT-E3/45 meets all primary substitution criteria with the following considerations: manufactured by Vishay General Semiconductor - Diodes Division, features an Isolated Tab variant of the TO-220-3 Full Pack, and maintains Active product status. Forward voltage specification differs at 770 mV @ 10 A versus 850 mV @ 10 A for the main part.

Parameter Comparison

Engineering Selection Recommendations

MBRF20100CTG (Direct Equivalent): This part is the primary substitute for the obsolete MBRF20100CTH. Both parts are manufactured by onsemi, share identical electrical specifications, and are packaged in the same TO-220-3 Full Pack configuration. MBRF20100CTG maintains Active product status with ROHS3 compliance and REACH Unaffected certification. This part provides direct functional and mechanical compatibility with no design modifications required.

MBRF20H100CT-E3/45 (Similar Substitute): This Vishay part meets all primary electrical and mechanical substitution criteria. The Isolated Tab variant of the TO-220-3 Full Pack may provide thermal or isolation advantages in specific circuit topologies. The lower forward voltage specification (770 mV @ 10 A versus 850 mV @ 10 A) and significantly lower reverse leakage current (4.5 µA @ 100 V versus 150 µA @ 100 V) represent measurable performance differences. This part maintains Active product status with ROHS3 compliance and REACH Unaffected certification. Circuit validation is required to confirm compatibility with the isolated tab configuration and to assess the impact of reduced forward voltage on system performance.

Frequently Asked Questions (FAQ)

Q: Can MBRF20100CTG be used as a direct replacement for MBRF20100CTH?

A: Yes. MBRF20100CTG is a direct equivalent. Both parts share identical electrical specifications, diode configuration, voltage ratings, current ratings, and TO-220-3 Full Pack packaging. The primary difference is product status: MBRF20100CTG is Active while MBRF20100CTH is Obsolete.

Q: What is the difference between the TO-220-3 Full Pack and the TO-220-3 Full Pack with Isolated Tab?

A: The MBRF20H100CT-E3/45 features an Isolated Tab variant, which electrically isolates the mounting tab from the diode array. The standard TO-220-3 Full Pack used in MBRF20100CTH and MBRF20100CTG does not provide this isolation. The isolated tab configuration may be required in applications where the mounting tab must be electrically isolated from the circuit ground or where thermal management requires isolation from the heat sink.

Q: Are there electrical differences between MBRF20100CTG and MBRF20H100CT-E3/45?

A: Yes. Forward voltage differs at 770 mV @ 10 A for the MBRF20H100CT-E3/45 versus 850 mV @ 10 A for both MBRF20100CTH and MBRF20100CTG. Reverse leakage current differs at 4.5 µA @ 100 V for the MBRF20H100CT-E3/45 versus 150 µA @ 100 V for MBRF20100CTH and MBRF20100CTG. These differences may affect power dissipation and circuit performance in applications with tight thermal or leakage specifications.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. MBRF20100CTG and MBRF20H100CT-E3/45 are both ROHS3 Compliant and REACH Unaffected, matching the compliance status of the main part MBRF20100CTH.

Q: What is the operating temperature range for these parts?

A: All three parts operate across a junction temperature range of -65°C to 175°C, providing identical thermal performance specifications.

Q: Can MBRF20H100CT-E3/45 be used in applications designed for MBRF20100CTH without circuit modifications?

A: Mechanical compatibility is confirmed for through-hole mounting in TO-220-3 Full Pack footprints. However, the Isolated Tab configuration requires verification that the circuit design accommodates or requires tab isolation. The lower forward voltage and reverse leakage specifications require circuit validation to confirm acceptable performance within the application's power dissipation and leakage current budgets.
