MBR1035CT Equivalent & Substitute Parts

Part Overview

The MBR1035CT is a Schottky diode array manufactured by Diodes Incorporated, configured as 1 Pair Common Cathode with a maximum reverse voltage of 35 V and average rectified current of 10 A per diode. The device is packaged in TO-220-3 through-hole configuration and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts with identical or superior electrical characteristics are necessary for ongoing design support and procurement continuity.

Engineering Selection Recommendations

VS-MBR2035CTHN3 (Vishay General Semiconductor - Diodes Division)

The VS-MBR2035CTHN3 is a direct functional equivalent to the MBR1035CT. This part maintains identical electrical specifications including 35 V reverse voltage, 10 A average rectified current per diode, 840 mV forward voltage at 10 A, and fast recovery characteristics. The diode configuration remains 1 Pair Common Cathode with TO-220-3 through-hole packaging. The operating temperature range extends to -65°C, providing enhanced low-temperature performance. The part is ROHS3 compliant and carries active product status, ensuring long-term availability and supply chain continuity. This substitute is suitable for direct replacement in existing designs.

MBR2035CT (Solid State Inc.)

The MBR2035CT offers enhanced current handling capability at 20 A average rectified current per diode, compared to the 10 A specification of the MBR1035CT. The reverse voltage rating remains 35 V. However, the diode configuration differs: MBR2035CT is configured as 2 Independent diodes rather than 1 Pair Common Cathode. This configuration change affects circuit topology and pin functionality. The part is ROHS3 compliant and maintains TO-220-3 through-hole packaging. Forward voltage and reverse leakage specifications are not provided for this part. Selection of this substitute requires circuit-level evaluation to confirm compatibility with the 2 Independent configuration.

Frequently Asked Questions (FAQ)

Q: Can the VS-MBR2035CTHN3 be used as a direct replacement for the MBR1035CT?

A: Yes. The VS-MBR2035CTHN3 maintains identical electrical specifications and diode configuration (1 Pair Common Cathode). Both parts share the same 35 V reverse voltage, 10 A average rectified current per diode, 840 mV forward voltage at 10 A, and fast recovery characteristics. The TO-220-3 through-hole package is identical. The extended operating temperature range of the Vishay part (-65°C to 150°C versus -55°C to 150°C) provides additional margin. Direct substitution is supported.

Q: What is the key difference between the MBR2035CT and the MBR1035CT?

A: The primary difference is diode configuration. The MBR1035CT is configured as 1 Pair Common Cathode, while the MBR2035CT is configured as 2 Independent diodes. Additionally, the MBR2035CT provides 20 A average rectified current per diode compared to 10 A in the MBR1035CT. These differences affect pin assignment and circuit topology. The MBR2035CT is not a direct replacement without circuit modification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the VS-MBR2035CTHN3 and MBR2035CT are ROHS3 compliant, matching the compliance status of the MBR1035CT. All three parts carry Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of the diode configuration difference?

A: Diode configuration determines internal circuit topology and pin functionality. The 1 Pair Common Cathode configuration in the MBR1035CT and VS-MBR2035CTHN3 means two diodes share a common cathode connection. The 2 Independent configuration in the MBR2035CT means each diode operates independently with separate connections. This affects how the component integrates into the circuit and cannot be overlooked during substitution.

Q: Why is the MBR1035CT classified as obsolete?

A: The MBR1035CT is listed as obsolete by the manufacturer. Active alternatives such as the VS-MBR2035CTHN3 are available to support ongoing design requirements and ensure supply chain continuity.

Q: Are the operating temperature ranges compatible?

A: The MBR1035CT operates from -55°C to 150°C. The VS-MBR2035CTHN3 operates from -65°C to 150°C, providing a wider low-temperature range. Both ranges encompass standard industrial and commercial operating conditions. The extended range of the Vishay part does not create incompatibility.
