MBR1035CT Equivalent & Substitute Parts

Part Overview

The MBR1035CT is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode arrangement in a TO-220-3 through-hole package. This component is rated for 35 V DC reverse voltage with 10 A average rectified current per diode and features fast recovery characteristics suitable for high-frequency switching applications. The part is currently in active product status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges, allowing for design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR1035CT is determined by the following critical parameters:

Mandatory Matching Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 35 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Allowable Parameter Variations:

• Current - Average Rectified (Io): Substitute parts must meet or exceed the 10 A requirement per diode
• Voltage - Forward (Vf): Substitute parts must not exceed the forward voltage specification at rated current
• Operating Temperature Range: Substitute parts must encompass or exceed the junction temperature range
• Speed Characteristics: Substitute parts must maintain fast recovery performance ≤ 500ns

The MBR1535CTG qualifies as a substitute based on matching diode configuration, Schottky technology, 35 V reverse voltage rating, through-hole mounting, and TO-220-3 package. However, the average rectified current rating of 7.5 A per diode is lower than the MBR1035CT specification of 10 A, which restricts its application to circuits requiring 7.5 A or less per diode.

Parameter Comparison

Engineering Selection Recommendations

MBR1035CT (Primary Selection): The MBR1035CT is the recommended component for new designs and active production applications. It maintains active product status with full manufacturer support, RoHS3 compliance, and the specified 10 A per diode current rating. This part is suitable for applications requiring the full 10 A rectified current capacity within the -55°C to 150°C junction temperature range.

MBR1535CTG (Constrained Substitution): The MBR1535CTG is available as a substitute only for applications where the average rectified current requirement does not exceed 7.5 A per diode. This part is classified as obsolete, indicating discontinued manufacturing and limited future availability. The substitute exhibits a higher forward voltage drop (840 mV @ 15 A versus 800 mV @ 10 A) and a wider operating temperature range (-65°C to 175°C). Selection of this substitute is restricted to legacy system maintenance or applications with reduced current demands and should not be used for new designs.

Both parts maintain identical diode configuration, Schottky technology, 35 V reverse voltage rating, fast recovery characteristics, and TO-220-3 package compatibility. RoHS3 compliance is confirmed for both components.

Frequently Asked Questions (FAQ)

Q: Can the MBR1535CTG directly replace the MBR1035CT in all applications?

A: No. The MBR1535CTG is rated for 7.5 A average rectified current per diode, compared to the MBR1035CT specification of 10 A. Direct substitution is limited to circuits designed for 7.5 A or lower current operation. Applications requiring the full 10 A capacity cannot use this substitute.

Q: What is the significance of the product status difference between these parts?

A: The MBR1035CT is classified as active, indicating ongoing manufacturing and manufacturer support. The MBR1535CTG is obsolete, meaning production has been discontinued. For new designs, the active MBR1035CT is the appropriate selection. The obsolete status of the MBR1535CTG restricts its use to legacy system maintenance only.

Q: Are the TO-220-3 packages physically identical between these parts?

A: Both parts use the TO-220-3 through-hole package, providing identical mechanical compatibility and PCB footprint. Physical installation and thermal management characteristics are equivalent.

Q: How does the forward voltage difference affect circuit performance?

A: The MBR1535CTG exhibits 840 mV forward voltage at 15 A compared to the MBR1035CT at 800 mV at 10 A. This 40 mV difference results in increased power dissipation in the substitute part. Circuit designs must account for this higher voltage drop when thermal management and efficiency are critical parameters.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MBR1035CT and MBR1535CTG are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). REACH status is unaffected for both components, and both carry the same ECCN and HTSUS classifications.

Q: What is the operating temperature advantage of the MBR1535CTG?

A: The MBR1535CTG operates across -65°C to 175°C junction temperature, compared to the MBR1035CT range of -55°C to 150°C. This provides a 10°C lower minimum and 25°C higher maximum operating temperature. However, this advantage does not offset the current rating limitation for most applications.
