MBR2535CTH Equivalent & Substitute Parts

Part Overview

The MBR2535CTH is a Schottky diode array manufactured by onsemi, configured as 1 pair common cathode with a maximum reverse voltage of 35 V and average rectified current of 15 A per diode. The device is packaged in TO-220-3 through-hole configuration and operates across a junction temperature range of -65°C to 175°C. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR2535CTH is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Maximum reverse voltage: 35 V
• Package type: TO-220-3 through-hole
• Fast recovery speed: ≤ 500ns, > 200mA (Io)
• Reverse leakage current: 200 µA @ 35 V
• RoHS3 compliance

Current Rating Consideration: The MBR2535CTH specifies 15 A average rectified current per diode. Substitute parts may have equal or higher current ratings while maintaining all other electrical parameters. Parts with lower current ratings are not acceptable substitutes.

Temperature Range: Operating junction temperature range must support the application requirements. The MBR2535CTH operates from -65°C to 175°C. Substitute parts with equal or wider temperature ranges are acceptable.

Parameter Comparison

Engineering Selection Recommendations

MBR2535CTG (onsemi): This part is a direct substitute from the same manufacturer. It maintains identical electrical specifications for reverse voltage, reverse leakage current, and recovery speed. The current rating is increased to 30 A, providing higher capacity than the original 15 A specification. The part is active in production status with ROHS3 compliance and identical operating temperature range (-65°C to 175°C). This substitute is suitable for applications requiring equal or higher current handling capability.

MBR2535CT-E3/45 (Vishay General Semiconductor - Diodes Division): This part is a similar substitute from an alternative manufacturer. It maintains the same 15 A current rating, reverse voltage, reverse leakage current, and recovery speed as the original MBR2535CTH. The operating temperature range is -65°C to 150°C, which is narrower than the original part by 25°C at the upper limit. The part is active in production status with ROHS3 compliance. This substitute is suitable for applications where the upper temperature limit of 150°C is acceptable.

Both substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can MBR2535CTG replace MBR2535CTH in all applications?

A: MBR2535CTG is electrically compatible with MBR2535CTH for all parameters specified. The higher current rating (30 A vs. 15 A) does not prevent substitution; it provides additional capacity. Mechanical compatibility is confirmed through identical TO-220-3 packaging. Substitution is valid provided the application does not require the specific 15 A current limitation.

Q: What is the key difference between MBR2535CTG and MBR2535CT-E3/45?

A: Both parts maintain the same 15 A current rating and 35 V reverse voltage as the original MBR2535CTH. The primary difference is the operating temperature range: MBR2535CTG supports -65°C to 175°C (matching the original), while MBR2535CT-E3/45 supports -65°C to 150°C. Additionally, MBR2535CTG is manufactured by onsemi (original manufacturer), while MBR2535CT-E3/45 is manufactured by Vishay.

Q: Are there any forward voltage differences between these parts?

A: The MBR2535CTH specifies 620 mV maximum forward voltage at 15 A. Both substitute parts specify 820 mV maximum forward voltage at 30 A. At the 15 A operating point, the actual forward voltage of the substitute parts may differ from the original specification. Circuit designs sensitive to forward voltage drop should account for this parameter variation.

Q: Is the TO-220-3 package identical across all three parts?

A: All three parts use TO-220-3 through-hole packaging. Mechanical and thermal characteristics are compatible for PCB layout and thermal management purposes.

Q: Which substitute should be selected for new designs?

A: Selection between MBR2535CTG and MBR2535CT-E3/45 depends on application requirements. If the full -65°C to 175°C temperature range is required, MBR2535CTG is the appropriate choice. If the application operates within -65°C to 150°C, either part is acceptable. MBR2535CTG offers the advantage of being from the original manufacturer with active production status.
