MBR3035CT Equivalent & Substitute Parts

Part Overview

The MBR3035CT is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode device rated for 35 V DC reverse voltage and 30 A average rectified current per diode. The component is packaged in a Through Hole TO-220-3 configuration and maintains Active product status with full RoHS3 compliance.

Substitute parts are identified for applications where the MBR3035CT may be unavailable, discontinued, or where alternative electrical characteristics within the same functional category are acceptable for the circuit design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR3035CT 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
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Variable Parameters (Acceptable Variance):

• Current - Average Rectified (Io) (per Diode): Lower ratings acceptable for reduced current applications
• Voltage - Forward (Vf) (Max) @ If: Variation acceptable within thermal and efficiency constraints
• Current - Reverse Leakage @ Vr: Variation acceptable within circuit requirements
• Operating Temperature - Junction: Extended ranges acceptable for wider environmental operation

Substitute parts 25CTQ035, 30CTQ035, and MBR1535CTG meet the mandatory matching criteria. However, all three substitute parts feature reduced current ratings (15 A or 7.5 A) compared to the primary part's 30 A specification, limiting their use to lower-current applications.

Parameter Comparison

Engineering Selection Recommendations

MBR3035CT (Primary Part) The MBR3035CT is the preferred selection for applications requiring 30 A average rectified current at 35 V reverse voltage. Active product status ensures ongoing availability and supply chain stability. Full RoHS3 compliance and REACH Unaffected status support regulatory requirements across global markets.

25CTQ035 (SMC Diode Solutions) The 25CTQ035 is suitable for applications with maximum current requirements of 15 A per diode. This part offers the lowest forward voltage drop (560 mV @ 15 A) among the substitute options, reducing thermal dissipation in lower-current circuits. Active product status and ROHS3 compliance are confirmed. REACH Affected status requires verification for specific regulatory jurisdictions.

30CTQ035 (SMC Diode Solutions) The 30CTQ035 provides 15 A current capacity with extended operating temperature range (-55 to 175°C), supporting applications requiring wider thermal operation windows. Forward voltage (620 mV @ 15 A) is intermediate between the 25CTQ035 and MBR1535CTG. Active product status and ROHS3 compliance are confirmed. REACH Affected status requires verification for specific regulatory jurisdictions.

MBR1535CTG (onsemi) The MBR1535CTG is rated for 7.5 A average rectified current and carries Obsolete product status. This part is not recommended for new designs. Existing applications using this component should transition to active alternatives. Extended operating temperature range (-65 to 175°C) and REACH Unaffected status do not offset the obsolescence designation.

Frequently Asked Questions (FAQ)

Q: Can the 25CTQ035 or 30CTQ035 directly replace the MBR3035CT in existing circuits?

A: Direct replacement is limited to applications where the circuit current requirement does not exceed 15 A per diode. The reduced current rating of these parts restricts their use to lower-power designs. Thermal and electrical performance characteristics differ due to lower current capacity and higher reverse leakage current (1 mA vs. 200 µA).

Q: What is the significance of the 1 Pair Common Cathode configuration?

A: This configuration indicates two diodes sharing a common cathode terminal within a single package. All listed substitute parts maintain this same configuration, ensuring pin-compatible operation in circuits designed for this topology.

Q: Why is the MBR1535CTG listed as Obsolete?

A: Obsolete product status indicates that the manufacturer has discontinued production and support. This part should not be selected for new designs. Existing inventory may be available, but long-term supply cannot be guaranteed.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage (Vf) determines the voltage drop across the diode during conduction. The MBR3035CT exhibits 820 mV @ 30 A, while the 25CTQ035 shows 560 mV @ 15 A. Lower forward voltage reduces power dissipation and heat generation, but direct comparison requires evaluation at equivalent current levels.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed parts including the primary MBR3035CT and substitutes 25CTQ035, 30CTQ035, and MBR1535CTG carry ROHS3 Compliant certification.

Q: What does REACH Affected status mean for the SMC parts?

A: REACH Affected status indicates that the part may contain substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Verification with the supplier is required for applications in regulated jurisdictions.

Q: Can the MBR1535CTG be used in new product designs?

A: No. Obsolete product status disqualifies this part from new designs. Active alternatives (25CTQ035, 30CTQ035, or MBR3035CT) must be selected to ensure supply chain continuity and manufacturer support.

Q: What is the difference between the 25CTQ035 and 30CTQ035?

A: Both parts are rated for 15 A current capacity and 35 V reverse voltage. The 30CTQ035 offers extended operating temperature range (-55 to 175°C vs. -55 to 150°C) and slightly higher forward voltage (620 mV vs. 560 mV @ 15 A). Selection depends on thermal environment requirements and acceptable power dissipation levels.
