MBR1035 Equivalent & Substitute Parts

Part Overview

The MBR1035 is a Schottky rectifier diode rated for 35 V DC reverse voltage and 10 A average rectified current in a through-hole TO-220AC package. Manufactured by Diodes Incorporated, this component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production builds and field replacements.

Substitute Part Grouping Explanation

Substitute parts for the MBR1035 are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 35 V
• Current - Average Rectified (Io): 10 A
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-220-2 or equivalent TO-220AC supplier package

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -65°C ~ 150°C

Substitute parts must satisfy all electrical equivalence criteria and mechanical compatibility requirements. Parts are grouped by their ability to function identically within the specified circuit application while maintaining physical and thermal compatibility with the original design.

VS-MBR1035-M3 (Vishay General Semiconductor - Diodes Division)

The VS-MBR1035-M3 is the primary parametric equivalent for the obsolete MBR1035. This part maintains identical electrical specifications across all critical parameters: 35 V reverse voltage rating, 10 A average rectified current, fast recovery Schottky technology, and matching reverse leakage characteristics. Both components share the same TO-220-2 package and through-hole mounting type, ensuring direct mechanical compatibility. The VS-MBR1035-M3 carries active product status with ROHS3 compliance and identical operating temperature range (-65°C ~ 150°C). This part is suitable for direct substitution in existing MBR1035 circuit designs.

MBR1035 (Solid State Inc.)

The Solid State Inc. MBR1035 meets all electrical equivalence criteria with matching voltage and current ratings, fast recovery speed, and Schottky technology. However, this part is packaged in DO-220AA surface-mount configuration, which differs from the original through-hole TO-220AC package. This mounting type difference requires PCB redesign and is not suitable for direct board-level substitution in through-hole applications. This part is applicable only when circuit board layout modifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the VS-MBR1035-M3 replace the obsolete MBR1035 without circuit modification?

A: Yes. The VS-MBR1035-M3 is a direct parametric equivalent with identical electrical ratings (35 V, 10 A), matching package type (TO-220-2), and through-hole mounting. No circuit modifications are required.

Q: Why is the Solid State Inc. MBR1035 listed as a substitute if it uses a different package?

A: The Solid State Inc. MBR1035 meets all electrical equivalence criteria and is electrically compatible. However, its DO-220AA surface-mount package requires PCB redesign and is not a direct board-level replacement. It is listed as a parametric equivalent for applications where board layout changes are feasible.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Voltage - DC Reverse (Vr) of 35 V, (2) Current - Average Rectified (Io) of 10 A, (3) Schottky technology, (4) Fast Recovery speed ≤ 500ns, (5) Through-hole mounting type, and (6) TO-220-2 package configuration for direct replacement.

Q: Are there differences in forward voltage characteristics between the MBR1035 and VS-MBR1035-M3?

A: The original MBR1035 specifies 840 mV forward voltage at 10 A. The VS-MBR1035-M3 specifies 840 mV at 20 A. Both parts meet the same forward voltage specification; the Vishay part is characterized at a higher current level, indicating equivalent or superior performance at the original operating point.

Q: What compliance certifications apply to substitute parts?

A: Both substitute parts carry ROHS3 compliance certification. The VS-MBR1035-M3 is REACH Unaffected. The Solid State Inc. part has REACH status listed as Vendor Undefined. Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Is the capacitance difference between MBR1035 and VS-MBR1035-M3 significant?

A: The original MBR1035 specifies 400 pF at 4 V, 1 MHz. The VS-MBR1035-M3 specifies 600 pF at 5 V, 1 MHz. This difference reflects measurement conditions rather than fundamental device differences and does not affect substitution suitability for standard rectifier applications.
