Product details
Overview
MBRF3035CT from Taiwan Semiconductor is a 30A, 35V dual-die Schottky barrier rectifier in ITO-220AB package, featuring 0.70 V max forward voltage at 15 A / 25°C, 200 A surge capability, and AEC-Q101 qualification option (H suffix). It serves as a high-efficiency output rectifier in compact AC/DC adapters and DC/DC converters.
For engineers reviewing the MBRF3035CT datasheet, MBRF3035CT pinout, MBRF3035CT application, or MBRF3035CT equivalent, key selection criteria include its 35 V repetitive peak reverse voltage, 4 °C/W junction-to-case thermal resistance, low 200 µA reverse leakage at 25°C, and suitability for high-frequency switching topologies requiring minimal conduction loss.
Technical Context
The MBRF3035CT integrates two independent Schottky diodes in a common-cathode configuration within a single ITO-220AB thermally enhanced package. Its 35 V VRRM rating targets mid-voltage secondary-side rectification where low VF and fast recovery are critical.
Designed with guard ring overvoltage protection and rated for 150°C maximum junction temperature, it supports continuous operation under high ambient conditions typical in enclosed power supplies. The 0.56 N·m mounting torque specification ensures reliable thermal interface to heatsinks without case cracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in DC/DC flyback or forward converter outputs. |
| IF | 30 A - Average forward current per diode; enables high-power density designs without parallel devices. |
| IFSM | 200 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overload events. |
| VF @ 15 A, 25°C | 0.70 V max - Low conduction loss directly reduces power dissipation and improves efficiency above 90% in 12–24 V output rails. |
| RθJC | 4 °C/W - Thermal resistance from junction to case; allows precise heatsink sizing for 30 A continuous operation at ≤125°C case temperature. |
| IR @ 25°C | 200 µA max - Reverse leakage per diode; minimizes standby power loss in energy-sensitive applications. |
Pinout & Package
Package: ITO-220AB - Thermally optimized plastic package with exposed metal tab for direct heatsink mounting; UL 94V-0 rated molding compound; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Case) | Cathode (Common) | Electrically connected to both diode cathodes; must be isolated from chassis unless circuit ground reference requires common-cathode tie. |
| Lead 1 | Anode 1 | First Schottky diode anode; used for independent or parallel connection of first diode leg. |
| Lead 2 | Anode 2 | Second Schottky diode anode; enables dual-output or interleaved rectification without external wiring. |

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-30CPQ035 | Same 35 V VRRM, 30 A IF, but TO-247AC package; higher RθJC = 5.5 °C/W; VF = 0.69 V typ @ 15 A. | Requires larger PCB footprint and different heatsink interface; no AEC-Q101 variant offered. | Select when legacy TO-247 layout exists or higher surge margin (250 A IFSM) is needed. |
| ON Semiconductor MBR3035CT | Identical electrical specs and ITO-220AB package; same pinout and marking; RoHS/halogen-free compliant. | No functional difference; validated in same automotive and industrial reference designs. | Drop-in alternative where Taiwan Semiconductor supply continuity is constrained; identical thermal and electrical behavior. |
Compared with VS-30CPQ035 and MBR3035CT, the MBRF3035CT offers superior thermal performance (4 vs 5.5 °C/W), AEC-Q101 availability, and identical mechanical fit to ON's part-making it optimal for space-constrained, thermally demanding, or automotive-qualified designs.

FAQ
What is the maximum junction temperature rating for the MBRF3035CT?
The MBRF3035CT has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as enclosed industrial power supplies. Derating curves in the datasheet confirm usable current capacity down to –55°C storage temperature. Thermal design must respect the 4 °C/W RθJC to maintain MBRF3035CT junction temperature within this limit under full 30 A load.
Does the MBRF3035CT have AEC-Q101 qualification?
The base MBRF3035CT is not AEC-Q101 qualified; however, the MBRF3035CTH variant-identical in all electrical and mechanical specifications-is explicitly qualified per AEC-Q101. The "H" suffix denotes qualification, including stress testing for temperature cycling, humidity bias, and high-temperature operating life. For automotive applications, specify MBRF3035CTH to ensure MBRF3035CT-level performance with automotive-grade reliability validation.
What is the forward voltage of the MBRF3035CT at 30 A and 125°C?
Per the electrical specifications table, the MBRF3035CT exhibits a maximum forward voltage (VF) of 0.73 V at IF = 30 A and TJ = 125°C. This value reflects real-world hot-operation performance critical for thermal modeling. At room temperature (25°C), VF is 0.82 V max under the same current. Both values are measured per diode, confirming MBRF3035CT's suitability for high-current, high-temperature rectification without excessive conduction loss.
How is the pinout configured for the dual-diode structure in the MBRF3035CT?
The MBRF3035CT uses a common-cathode configuration: the metal tab (case) is the shared cathode for both diodes, Lead 1 is Anode 1, and Lead 2 is Anode 2. This arrangement enables independent control of each diode leg-ideal for dual-output supplies-or parallel connection for higher current. Polarity is marked on the device body; correct mounting orientation ensures proper thermal and electrical interface. No internal connection exists between anodes, preserving isolation integrity in MBRF3035CT applications.
What packaging and ordering options are available for the MBRF3035CT?
The MBRF3035CT is supplied in ITO-220AB package, packed 50 units per tube. The standard ordering code is MBRF3035CT; the AEC-Q101 qualified version uses MBRF3035CTH. Both variants share identical electrical specs, pinout, and thermal characteristics. Tape-and-reel packaging is not offered-only tube format-supporting manual and semi-automated assembly. Date codes follow YWW format (e.g., "2422" = 2024, week 22), and green compound (halogen-free) is standard per IEC 61249-2-21, confirmed on MBRF3035CT reels and tubes.
