MBR2535CT Equivalent & Substitute Parts

Part Overview

The MBR2535CT is a Schottky diode array in a 1 Pair Common Cathode configuration rated for 35 V DC reverse voltage and 30 A average rectified current per diode. Manufactured by onsemi, this component features fast recovery characteristics (≤500 ns) and is housed in a TO-220-3 through-hole package. The part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the MBR2535CT is determined by the following critical parameters: diode configuration (1 Pair Common Cathode), technology (Schottky), voltage rating (35 V DC reverse), current rating (30 A average rectified), forward voltage characteristics, reverse leakage current, speed classification (fast recovery), and package type (TO-220-3 through-hole).

Substitute parts are grouped into three categories:

Direct Substitutes (Identical Electrical and Mechanical Specifications): Parts that maintain all key electrical parameters including 35 V rating, 30 A current capacity, 820 mV forward voltage at 30 A, and TO-220-3 packaging. These parts are functionally interchangeable with the MBR2535CT.

Similar Substitutes (Reduced Current Rating): Parts that maintain the 35 V voltage rating and TO-220-3 package but operate at reduced current levels (15 A instead of 30 A). These parts are suitable for applications where the full 30 A capacity is not required.

Parametric Equivalents (Different Package): Parts that maintain the 35 V voltage rating and 30 A current capacity but are housed in alternative through-hole packages (TO-247-3). These parts provide equivalent electrical performance with different mechanical form factors.

Engineering Selection Recommendations

Primary Direct Substitute: MBR2535CTG (onsemi) is the recommended direct replacement for the obsolete MBR2535CT. This part maintains identical electrical specifications (35 V, 30 A, 820 mV forward voltage) and TO-220-3 packaging while offering active product status and ROHS3 compliance. The part is currently in active production with substantial inventory availability.

Alternative Direct Substitute: MBR3035CTHC0G (Taiwan Semiconductor Corporation) provides equivalent electrical performance with 35 V rating, 30 A current capacity, and identical forward voltage characteristics. This part includes automotive-grade qualification (AEC-Q101) and is available in TO-220-3 packaging with active product status and ROHS3 compliance.

Reduced Current Substitutes: For applications requiring less than 30 A capacity, MBR2535CTL (SMC Diode Solutions), 25CTQ035 (SMC Diode Solutions), 30CTQ035 (SMC Diode Solutions), and MBR2535CT-E3/45 (Vishay) are available as 15 A rated alternatives. All maintain the 35 V voltage rating and TO-220-3 package format with active product status and ROHS3 compliance.

Higher Voltage Alternative: STPS3045CT (STMicroelectronics) offers a 45 V rating with 15 A capacity in TO-220-3 packaging. This part is suitable for applications requiring higher voltage margin while accepting reduced current capacity.

Alternative Package Options: MBR3035PT C0G and MBR3035PTHC0G (Taiwan Semiconductor Corporation) provide 35 V, 30 A equivalent performance in TO-247-3 through-hole packaging. These parts are suitable for designs where the larger TO-247 form factor is acceptable or preferred for thermal management.

Frequently Asked Questions (FAQ)

Q: Can MBR2535CTG be used as a direct replacement for MBR2535CT?

A: Yes. MBR2535CTG maintains identical electrical specifications including 35 V DC reverse voltage, 30 A average rectified current, 820 mV forward voltage at 30 A, and TO-220-3 packaging. The primary differences are active product status and ROHS3 compliance.

Q: What is the difference between MBR2535CTL and MBR2535CT?

A: MBR2535CTL is manufactured by SMC Diode Solutions rather than onsemi and exhibits different forward voltage characteristics (470 mV @ 12.5 A versus 820 mV @ 30 A). The current rating is not specified for MBR2535CTL. Both parts maintain 35 V voltage rating and TO-220-3 packaging.

Q: Can 25CTQ035 or 30CTQ035 be used in place of MBR2535CT?

A: These parts are suitable only for applications where the full 30 A capacity is not required. Both are rated for 15 A average rectified current compared to the MBR2535CT's 30 A rating. Voltage rating (35 V) and package (TO-220-3) are maintained. Forward voltage characteristics differ: 560 mV @ 15 A for 25CTQ035 and 620 mV @ 15 A for 30CTQ035.

Q: What is the advantage of MBR3035CTHC0G over MBR2535CTG?

A: MBR3035CTHC0G includes automotive-grade qualification (AEC-Q101) in addition to maintaining identical electrical specifications and TO-220-3 packaging. This qualification is relevant for automotive applications requiring specific reliability and testing standards.

Q: Can STPS3045CT replace MBR2535CT?

A: STPS3045CT is suitable only for applications where the reduced 15 A current capacity is acceptable. The part offers a higher 45 V voltage rating, which provides additional voltage margin. Forward voltage is 570 mV @ 15 A. TO-220-3 packaging is maintained.

Q: What are the package differences between TO-220-3 and TO-247-3 options?

A: TO-220-3 and TO-247-3 are both through-hole packages with different physical dimensions. TO-247-3 is larger and typically offers improved thermal performance. MBR3035PT C0G and MBR3035PTHC0G provide 35 V, 30 A equivalent performance in TO-247-3 packaging for designs where this form factor is acceptable.

Q: Are there RoHS compliance considerations for substitute selection?

A: Yes. The original MBR2535CT is RoHS non-compliant. All active substitute parts listed (MBR2535CTG, MBR2535CTL, 25CTQ035, 30CTQ035, MBR2535CT-E3/45, STPS3045CT, MBR3035CTHC0G, MBR3035PT C0G, MBR3035PTHC0G) are ROHS3 compliant, meeting current regulatory requirements.

Q: What is the operating temperature range difference between MBR2535CT and its substitutes?

A: MBR2535CT operates from -65°C to 175°C. Most substitutes operate from -55°C to 150°C, representing a narrower range. MBR2535CT-E3/45 operates from -65°C to 150°C. STPS3045CT specifies 200°C maximum junction temperature. Application temperature requirements should be verified against substitute specifications.
