MBR1030CT Equivalent & Substitute Parts

Part Overview

The MBR1030CT is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode arrangement in a TO-220-3 through-hole package. This component is rated for 30 V DC reverse voltage and 10 A average rectified current per diode, with a maximum forward voltage of 840 mV at 10 A. The MBR1030CT is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, forward voltage characteristics, and thermal operating range while accommodating the through-hole TO-220-3 package format.

Substitute parts for the MBR1030CT are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• Current - Average Rectified (Io): 10 A per diode
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Parameter Variations:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 30 V
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 840 mV @ 10 A
• Operating Temperature - Junction: Equal to or greater than the -55°C to 150°C range

Engineering Selection Recommendations

MBR2030CTLG (onsemi) is a direct electrical equivalent with identical voltage and current ratings. This part carries ROHS3 compliance and operates across an extended temperature range (-65 to 175 °C), providing superior thermal performance. The forward voltage is reduced to 520 mV @ 10 A, resulting in lower power dissipation compared to the MBR1030CT. However, the MBR2030CTLG is classified as Last Time Buy, indicating limited future availability. This part is suitable for applications where lower forward voltage and extended temperature operation provide design advantages.

VS-MBR2035CTHN3 (Vishay General Semiconductor - Diodes Division) provides a higher voltage rating of 35 V while maintaining the 10 A current specification and identical forward voltage of 840 mV @ 10 A. This part is classified as Active, ensuring ongoing availability and supply continuity. The VS-MBR2035CTHN3 is ROHS3 compliant and REACH Unaffected. The elevated voltage rating accommodates applications requiring additional reverse voltage margin. This part is recommended for new designs and long-term production requirements.

Both substitute parts maintain the 1 Pair Common Cathode configuration, Schottky technology, fast recovery speed, and TO-220-3 through-hole package format required for direct substitution in circuits designed for the MBR1030CT.

Frequently Asked Questions (FAQ)

Q: Can the MBR2030CTLG replace the MBR1030CT in all applications?

A: The MBR2030CTLG is electrically equivalent with identical 30 V reverse voltage and 10 A current ratings. Both parts share the same diode configuration, technology, and package. The MBR2030CTLG exhibits lower forward voltage (520 mV versus 840 mV @ 10 A) and extended operating temperature range (-65 to 175 °C versus -55 to 150 °C). Substitution is valid for circuits designed within these electrical parameters. However, the MBR2030CTLG is classified as Last Time Buy, limiting future procurement availability.

Q: What is the advantage of the VS-MBR2035CTHN3 over the MBR1030CT?

A: The VS-MBR2035CTHN3 provides a 35 V reverse voltage rating compared to the MBR1030CT's 30 V rating, offering additional reverse voltage margin in circuit designs. Both parts maintain identical 10 A current capacity, 840 mV forward voltage @ 10 A, and fast recovery speed characteristics. The VS-MBR2035CTHN3 is classified as Active, ensuring continued availability. The higher voltage rating accommodates applications with elevated reverse voltage requirements or designs requiring additional safety margin.

Q: Are all substitute parts available in the same TO-220-3 package?

A: Yes. The MBR2030CTLG and VS-MBR2035CTHN3 are both supplied in TO-220-3 through-hole packages, identical to the MBR1030CT. No PCB layout modifications are required for substitution. Both parts are compatible with existing through-hole mounting processes and thermal management solutions designed for the original component.

Q: What is the difference in reverse leakage current between these parts?

A: The MBR1030CT specifies 100 µA @ 30 V reverse leakage. The MBR2030CTLG exhibits 5 mA @ 30 V, representing higher leakage current. The VS-MBR2035CTHN3 specifies 100 µA @ 35 V, matching the original part's leakage characteristic at its rated voltage. For applications sensitive to reverse leakage current, the VS-MBR2035CTHN3 provides performance equivalent to the MBR1030CT.

Q: Are these parts RoHS and REACH compliant?

A: All three parts are ROHS3 compliant. The MBR1030CT and MBR2030CTLG are REACH Affected. The VS-MBR2035CTHN3 is REACH Unaffected. For applications requiring REACH Unaffected status, the VS-MBR2035CTHN3 is the appropriate selection.

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

A: The VS-MBR2035CTHN3 is recommended for new designs due to its Active product status, ensuring long-term availability and supply continuity. The elevated 35 V reverse voltage rating provides additional design margin. The MBR2030CTLG is classified as Last Time Buy and should be reserved for legacy product support or applications where the lower forward voltage and extended temperature range provide specific design advantages.
