Product details
Overview
MBRF2035CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 20A average forward current, 35V repetitive peak reverse voltage, and 150A surge current. It delivers low forward voltage (0.84V at 20A, 25°C), operates up to 150°C junction temperature, and is used in high-efficiency AC/DC adapters and DC-DC converters where thermal performance and fast switching are critical.
For engineers reviewing the MBRF2035CT datasheet, MBRF2035CT pinout, MBRF2035CT application, or MBRF2035CT equivalent, key selection criteria include its 35V VRRM, dual-common-cathode configuration, 1.5°C/W junction-to-case thermal resistance, AEC-Q101 qualification option (H suffix), and UL recognition under file E-326243.
Technical Context
The MBRF2035CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its guard ring structure provides overvoltage protection, and it supports high dv/dt (10,000 V/µs) for robust operation in fast-switching topologies.
Designed for continuous conduction mode in SMPS outputs, it exhibits low reverse recovery charge (inherent to Schottky architecture), minimal power loss at 20A load, and stable leakage (<100 µA at 25°C, <15 mA at 125°C) across its operating temperature range of –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum reverse blocking capability without breakdown; defines usable input/output voltage margin in 12–24V DC-DC or adapter secondary-side rectification. |
| IF | 20 A - Continuous average forward current per diode; supports high-power output stages without forced air cooling when mounted on heatsink. |
| IFSM | 150 A - Non-repetitive surge rating (8.3 ms half-sine); withstands inrush and transient overload in power supplies during startup or fault conditions. |
| VF @ 20A, 25°C | 0.84 V - Low conduction loss per diode; reduces power dissipation to ~16.8 W total (2 × 0.84 V × 20 A) at full load, improving system efficiency. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables predictable thermal design with heatsink interface, supporting >15W power dissipation before reaching 150°C junction limit. |
| TJ max | 150 °C - Maximum allowable junction temperature; allows operation in sealed industrial enclosures or high-ambient environments with appropriate thermal management. |
Pinout & Package
Package: ITO-220AB - Thermally optimized 3-terminal plastic package with exposed metal tab (cathode-connected) for direct heatsink mounting; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab / Pin 1 | Common Cathode | Electrically connected to both diode cathodes; serves as primary thermal path and must be electrically isolated from chassis unless circuit reference requires cathode grounding. |

| Pin 3 | Anode 2 | Input terminal for second Schottky diode; enables dual-output or parallel rectification with shared cathode return path. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events (e.g., line surges or inductive kickback), extending reliability in unregulated or marginally filtered inputs. |
| AEC-Q101 qualified version available (MBRF2035CTH) | Validated for automotive under-hood applications including engine control modules and body electronics requiring extended temperature and lifetime validation. |
| UL Recognized File # E-326243 | Confirms compliance with safety standards for end-equipment certification (e.g., ITE, industrial power supplies), reducing time-to-market for regulatory approvals. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive; supports environmentally regulated manufacturing and export requirements without material substitution risk. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPQ035 | Same 35V VRRM, 20A IF, TO-220AC package; slightly higher VF (0.86V @ 20A) and RθJC (2.0°C/W). | Lacks AEC-Q101 option and UL recognition; suitable for commercial-grade SMPS but not automotive. | Select when cost sensitivity outweighs automotive qualification or UL certification needs. |
| ON Semiconductor MBR2035CT | Identical electrical specs and ITO-220AB package; same pinout and thermal performance; RoHS/halogen-free compliant. | No AEC-Q101 variant offered; UL file number differs (E237405). | Drop-in alternative where Taiwan Semiconductor supply continuity is constrained; verify UL documentation alignment with end-equipment requirements. |
Compared with VS-20CPQ035 and MBR2035CT, the MBRF2035CT offers superior thermal resistance (1.5°C/W vs. 2.0°C/W), UL recognition for safety-critical designs, and an AEC-Q101-qualified variant-making it preferred for thermally demanding or automotive-qualified systems.

FAQ
What is the maximum junction temperature rating for the MBRF2035CT?
The MBRF2035CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows continuous operation in high-ambient environments when properly heatsinked. Derating curves confirm usable current down to ~12A at 100°C case temperature. The MBRF2035CT must not exceed this limit to maintain reliability and avoid parametric shift or premature failure.
Does the MBRF2035CT have AEC-Q101 qualification?
The standard MBRF2035CT is not AEC-Q101 qualified, but the MBRF2035CTH variant-identical in all electrical and thermal specifications-is explicitly qualified per AEC-Q101 Rev D for automotive applications. The "H" suffix denotes qualification, and the device meets stress testing for temperature cycling, humidity, and mechanical shock. For automotive use, specify MBRF2035CTH-not MBRF2035CT-to ensure compliance.
What is the pin configuration and polarity marking for the MBRF2035CT?
The MBRF2035CT uses an ITO-220AB package with three terminals: Pin 1 (metal tab) is the common cathode, Pin 2 is Anode 1, and Pin 3 is Anode 2. Polarity is marked on the device body with a cathode band adjacent to Pin 1. The tab is electrically connected to the cathode and must be isolated from ground unless the circuit design requires cathode referencing to chassis or heatsink potential.
How does the forward voltage of the MBRF2035CT vary with temperature and current?
At 25°C junction temperature, the MBRF2035CT exhibits 0.84V typical forward voltage at 20A. At 125°C, VF drops to 0.72V due to the negative temperature coefficient of Schottky diodes. This reduction improves conduction efficiency at elevated temperatures but requires careful thermal design to avoid thermal runaway in parallel configurations. Data is confirmed in the Electrical Specifications table on page 3 of the Taiwan Semiconductor datasheet.
Is the MBRF2035CT lead-free and RoHS compliant?
Yes, the MBRF2035CT is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound is UL 94V-0 rated. These attributes are documented in the Mechanical Data and Ordering Information sections of the official Taiwan Semiconductor datasheet (Version O2105), confirming suitability for green manufacturing and global export.
