Product details
Overview
MBRF835CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 8 A average forward current, 35 V repetitive peak reverse voltage, and 150 A non-repetitive surge current; it delivers low forward voltage (0.55 V max at 4 A, 25°C) and operates up to 150°C junction temperature, used in high-efficiency AC/DC adapters and DC-DC converters.
For engineers reviewing the MBRF835CT datasheet, MBRF835CT pinout, MBRF835CT application, or MBRF835CT equivalent, key selection criteria include its 35 V VRRM, dual-common-cathode configuration, 6 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (MBRF835CTH), and UL recognition (E-326243).
Technical Context
The MBRF835CT integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package with common cathode connection, enabling full-wave rectification without external wiring. Its guard ring structure provides overvoltage protection, and it sustains 10,000 V/µs critical rate of rise of off-state voltage.
Designed for high-frequency switching applications, the device exhibits low reverse recovery charge and negligible reverse recovery time due to Schottky architecture. At 125°C, reverse leakage remains ≤15 mA per diode under rated 35 V reverse bias, supporting stable operation in thermally constrained power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in rectifier bridge or output stage |
| IF | 8 A - Continuous average forward current per diode; determines heatsink sizing in 50–100 kHz SMPS designs |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); supports cold-start and line-transient robustness |
| VF | ≤0.55 V @ 4 A, 25°C - Low conduction loss per diode; reduces power dissipation by ~30% vs. standard PN rectifiers |
| RθJC | 6 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsink without thermal pad derating |
| TJ max | 150 °C - Maximum allowable junction temperature; allows operation in sealed enclosures up to 85°C ambient |
| IR | ≤100 µA @ 35 V, 25°C - Low reverse leakage per diode; minimizes standby power loss in energy-efficient adapters |
Pinout & Package

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-8TQ035 | Same ITO-220AB package, 8 A/35 V rating, but 0.57 V VF max (vs. 0.55 V); RθJC = 7.5 °C/W | No AEC-Q101 option; UL file not published; halogen-free status unspecified | Select when UL recognition or automotive qualification is not required and thermal margin permits higher RθJC |
| ON Semiconductor MBR835CT | Identical electrical specs and ITO-220AB footprint; same 0.55 V VF max and 6 °C/W RθJC; RoHS/halogen-free compliant | Not AEC-Q101 qualified in standard grade; UL file # E237113 differs from TSC's E-326243 | Preferred for cross-manufacturer BOM redundancy where AEC-Q101 is optional and UL file alignment is secondary |
Compared with MBRF835CT, VS-8TQ035 trades slightly higher conduction loss and thermal resistance for broader distributor availability, while MBR835CT offers identical performance with alternate certification-both require validation of marking, date code, and reel/tube packaging compatibility before substitution.

FAQ
What is the pin configuration of the MBRF835CT?
The MBRF835CT uses a three-terminal ITO-220AB package with dual-anode, common-cathode configuration: Tab = Anode 1, Lead 1 = Anode 2, Lead 2 = Common Cathode. Polarity is marked on the device body. This layout supports full-wave rectification without external interconnects and enables direct heatsink mounting via the insulated tab.
Is the MBRF835CT suitable for automotive applications?
The standard MBRF835CT is not AEC-Q101 qualified, but the MBRF835CTH variant is. MBRF835CTH undergoes temperature cycling, highly accelerated life testing, and bias-HTRB per AEC-Q101 Rev D. For automotive infotainment or body control modules, specify MBRF835CTH-not MBRF835CT-to ensure qualification compliance.
What is the maximum junction temperature rating for the MBRF835CT?
The MBRF835CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table. Operation at this limit requires thermal design ensuring case temperature stays ≤115°C when dissipating 3.5 W (based on RθJC = 6 °C/W), typically achieved with ≥15 cm² copper pour and forced airflow.
Does the MBRF835CT have UL recognition?
Yes, the MBRF835CT carries UL Recognition under File # E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for use in secondary circuits of power supplies. This applies to both standard and AEC-Q101 variants and covers flammability (UL 94V-0), dielectric strength, and creepage/clearance requirements.
How does the guard ring feature benefit the MBRF835CT in real-world designs?
The guard ring in the MBRF835CT enhances edge termination robustness, preventing localized avalanche breakdown during voltage transients such as AC line surges or inductive kickback. In practice, this extends mean time to failure by >2× in 230 VAC-input SMPS subjected to repeated 1.5 kV surge testing per IEC 61000-4-5, reducing field returns linked to rectifier failure.
