Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRB2035CTHE3_A/I are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Current - Average Rectified (Io): 10 A per diode
• Mounting Type: Surface Mount
• Package / Case: TO-263-3 D2PAK variants

Secondary Compatibility Parameters:

• Voltage - DC Reverse (Vr): Equal to or greater than 35 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature Range: Must encompass application requirements
• Grade and Qualification: Automotive grade with AEC-Q101 certification preferred for equivalent applications

Substitute parts meeting these criteria can be directly substituted in applications designed for the MBRB2035CTHE3_A/I, provided that the electrical characteristics remain within the design specifications of the target application.

Engineering Selection Recommendations

V20D45CHM3/I (Vishay General Semiconductor - Diodes Division)

This substitute is an active product with automotive-grade qualification and AEC-Q101 certification, matching the compliance profile of the obsolete MBRB2035CTHE3_A/I. The V20D45CHM3/I provides a higher reverse voltage rating of 45 V, which exceeds the 35 V requirement of the original part. The forward voltage is lower at 570 mV @ 10 A compared to 650 mV @ 10 A, resulting in improved efficiency. The operating temperature range of -40°C ~ 150°C is narrower at the lower bound but covers the upper temperature requirement. This part is suitable for direct substitution in applications where the lower minimum operating temperature is acceptable.

MBRS1035CT MNG (Taiwan Semiconductor Corporation)

This substitute maintains the same 35 V reverse voltage rating and 10 A current specification as the original MBRB2035CTHE3_A/I. The package and mounting type are identical. However, the forward voltage is higher at 800 mV @ 10 A, indicating greater power dissipation. The operating temperature range of -55°C ~ 150°C provides broader low-temperature coverage than the original part. This part lacks specified automotive grade and AEC-Q101 qualification. Selection of this substitute should be limited to non-automotive applications or where automotive qualification is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can the V20D45CHM3/I be used as a direct replacement for the MBRB2035CTHE3_A/I?

A: The V20D45CHM3/I is functionally compatible for direct substitution in applications where the operating temperature minimum of -40°C is acceptable. The higher reverse voltage rating (45 V vs. 35 V) and lower forward voltage (570 mV vs. 650 mV @ 10 A) are advantageous characteristics. Both parts share automotive-grade qualification and AEC-Q101 certification, ensuring compliance equivalence.

Q: What are the key differences between the V20D45CHM3/I and MBRS1035CT MNG?

A: The V20D45CHM3/I is manufactured by Vishay with automotive qualification and AEC-Q101 certification, while the MBRS1035CT MNG is manufactured by Taiwan Semiconductor Corporation without specified automotive qualification. The V20D45CHM3/I has a higher reverse voltage (45 V) and lower forward voltage (570 mV @ 10 A), whereas the MBRS1035CT MNG matches the original 35 V rating but has higher forward voltage (800 mV @ 10 A). The MBRS1035CT MNG provides a wider low-temperature operating range (-55°C vs. -40°C).

Q: Are all substitute parts in the same package?

A: All substitute parts use the TO-263-3 D2PAK surface mount package with 2 leads plus tab. The MBRB2035CTHE3_A/I and MBRS1035CT MNG both specify TO-263AB, while the V20D45CHM3/I uses a TO-263-3 D2PAK variant. These packages are mechanically and electrically compatible for PCB assembly.

Q: Which substitute is recommended for automotive applications?

A: The V20D45CHM3/I is the recommended substitute for automotive applications. It maintains automotive-grade classification and AEC-Q101 qualification, matching the compliance requirements of the original MBRB2035CTHE3_A/I. The MBRS1035CT MNG lacks specified automotive qualification and should not be used in automotive designs without additional qualification review.

Q: How does forward voltage affect circuit performance?

A: Forward voltage directly impacts power dissipation and heat generation in the diode. The V20D45CHM3/I operates at 570 mV @ 10 A, resulting in lower power loss compared to the original 650 mV @ 10 A specification. The MBRS1035CT MNG operates at 800 mV @ 10 A, resulting in higher power dissipation. Circuit thermal management and efficiency calculations must account for these differences.

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

A: The MBRB2035CTHE3_A/I and MBRS1035CT MNG both specify 100 µA @ 35 V reverse leakage. The V20D45CHM3/I specifies 1 mA @ 45 V, which is measured at a higher voltage. Reverse leakage affects standby power consumption and circuit performance in high-impedance applications. The higher leakage specification of the V20D45CHM3/I should be evaluated against application requirements.

Q: Can the MBRS1035CT MNG be used in automotive designs?

A: The MBRS1035CT MNG lacks specified automotive-grade classification and AEC-Q101 qualification. Use in automotive applications requires independent qualification and approval by the design authority. For automotive designs, the V20D45CHM3/I is the appropriate substitute.
