Product details
Overview
MBR2535CT from Taiwan Semiconductor is a 25A, 35V dual-die Schottky barrier rectifier in TO-220AB package, featuring low forward voltage (0.82 V at 25 A, 25°C), high surge current capability (200 A), and AEC-Q101 qualification option. It serves as a primary output rectifier in high-efficiency SMPS for industrial power supplies.
For engineers reviewing the MBR2535CT datasheet, MBR2535CT pinout, MBR2535CT application, or MBR2535CT equivalent, key selection criteria include repetitive peak reverse voltage (35 V), junction-to-case thermal resistance (1 °C/W), guard ring protection, and TO-220AB mounting compatibility with 0.56 N·m torque limit.
Technical Context
The MBR2535CT integrates two independent Schottky diodes in a single TO-220AB package with common cathode configuration. Its low VF and high IFSM support high-frequency switching topologies where conduction loss minimization and transient robustness are critical.
Thermal performance is defined by RθJC = 1 °C/W and TJ operating range of –55°C to +150°C. Reverse leakage remains ≤200 µA at 25°C and ≤15 mA at 125°C under rated VR, enabling stable operation in thermally constrained DC–DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per diode; sets upper limit for output rectification in 12–24 V DC bus systems. |
| IF | 25 A - Continuous average forward current per diode; supports high-power secondary-side rectification without forced air cooling. |
| IFSM | 200 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in SMPS startup and overload conditions. |
| VF @ 25A, 25°C | 0.82 V - Forward voltage drop per diode; directly determines conduction loss (20.5 W total for both diodes at full load). |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; enables predictable heatsink sizing when mounted with ≤0.56 N·m torque on standard TO-220 heatsinks. |
| IR @ 35V, 25°C | ≤200 µA - Max reverse leakage per diode; ensures minimal standby power loss in offline adapters and energy-efficient designs. |
Pinout & Package
Package: TO-220AB, 3-terminal case with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, 1.90 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Case) | Cathode (common) | Electrically connected to both diode cathodes; requires insulating washer if mounted to grounded heatsink. |
| Lead 1 | Anode 1 | Input terminal for first Schottky diode; used for dual-output or interleaved rectifier configurations. |
| Lead 2 | Anode 2 | Input terminal for second Schottky diode; enables independent control or parallel operation with shared cathode return path. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Provides edge termination to suppress avalanche breakdown and improve VRRM consistency across temperature and process variation. |
| AEC-Q101 qualified version available | MBR2535CTH variant meets stress test requirements for automotive under-hood power conversion applications. |
| Low thermal resistance | RθJC = 1 °C/W enables >20 W dissipation with ≤20°C rise above heatsink temperature at 25 A DC. |
| High dv/dt rating | 10,000 V/µs immunity supports reliable operation in fast-switching GaN- or SiC-based converters without snubber circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-25CPQ035 | Same 35 V VRRM, 25 A IF, TO-220AC package (isolated tab), VF = 0.78 V @ 25 A, 25°C; no AEC-Q101 option. | Lower VF improves efficiency marginally but lacks guard ring; not qualified for automotive use. | Select for cost-sensitive industrial adapters where AEC-Q101 is unnecessary and 0.04 V lower VF justifies sourcing change. |
| ON Semiconductor MBR2535CT | Identical electrical specs and TO-220AB package; same marking code and thermal resistance; RoHS/halogen-free compliant. | No functional difference; direct second-source alternative with identical footprint and thermal behavior. | Choose for supply chain diversification while maintaining full design compatibility and BOM continuity. |
Compared with VS-25CPQ035 and ON Semiconductor's MBR2535CT, the Taiwan Semiconductor MBR2535CT offers unique AEC-Q101 qualification (via H-suffix) and integrated guard ring-critical for automotive-grade reliability-while matching core electrical and thermal performance of both alternatives.

FAQ
What is the maximum junction temperature rating for the MBR2535CT?
The MBR2535CT has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from –55°C to +150°C. This rating allows sustained operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules when paired with appropriate heatsinking based on its 1 °C/W RθJC.
Does the MBR2535CT have a common cathode configuration?
Yes, the MBR2535CT uses a common-cathode dual-die configuration: both anodes are electrically isolated (Leads 1 and 2), while the metal tab serves as the shared cathode connection. This layout supports dual-output rectification or paralleled anode operation with a single thermal path, as confirmed in the TO-220AB pinout and marking diagram.
Is the MBR2535CT RoHS and halogen-free compliant?
Yes, the MBR2535CT is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements are explicitly documented in the official Taiwan Semiconductor datasheet revision K2104, covering material content, plating (matte tin), and molding compound specifications.
What is the forward voltage drop of the MBR2535CT at full rated current?
The MBR2535CT exhibits a typical forward voltage (VF) of 0.82 V per diode at 25 A and 25°C, measured under pulsed conditions with 0.3 ms pulse width. At 125°C junction temperature and 25 A, VF drops to 0.73 V due to negative temperature coefficient inherent to Schottky diodes.
How does the guard ring feature benefit the MBR2535CT in practical designs?
The guard ring in the MBR2535CT enhances edge termination uniformity, suppressing premature avalanche breakdown at high dv/dt or elevated temperatures. In practice, this improves VRRM consistency across production lots and extends safe operating area during transient overvoltage events-particularly valuable in unregulated SMPS outputs or flyback snubberless designs.
