Product details
Overview
MBRF1535CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 15 A average forward current, 35 V repetitive peak reverse voltage, and 150 A surge current, delivering low forward voltage (0.84 V at 15 A, 25°C) for high-efficiency DC/DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRF1535CT datasheet, MBRF1535CT pinout, MBRF1535CT application, or MBRF1535CT equivalent, key selection criteria include its 35 V VRRM, dual-common-cathode configuration, 3.5 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (H-suffix), and UL recognition (E-326243).
Technical Context
The MBRF1535CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection, enabling synchronous or interleaved rectification topologies. Its guard ring structure provides overvoltage protection, and it supports operation from –55°C to +150°C junction temperature.
With a typical forward voltage of 0.57 V at 7.5 A and 125°C, and reverse leakage of only 500 µA at 25°C and rated VR, the device maintains efficiency under elevated thermal stress while meeting JESD201 Class 2 whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per diode; defines usable input/output voltage range in buck or flyback secondary side |
| IF | 15 A - Continuous average forward current per diode; determines heatsink sizing and conduction loss budget |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); enables robustness against line transients and startup inrush |
| VF | 0.84 V @ 15 A, 25°C - Low conduction loss directly reduces power dissipation and improves system efficiency |
| RθJC | 3.5 °C/W - Thermal resistance from junction to case; allows accurate thermal modeling when mounted to heatsink |
| IR | 500 µA @ 35 V, 25°C - Low reverse leakage preserves efficiency in high-impedance bias networks and standby modes |
| TJ max | +150°C - Maximum operating junction temperature; supports high-ambient industrial and automotive under-hood environments |
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-15CTQ035 | Same 35 V VRRM, 15 A IF, but TO-220AC package (single anode); no common-cathode configuration | Requires external cathode tie for dual-anode use; less space-efficient in dual-output designs | Select when single-diode topology suffices and footprint compatibility with legacy TO-220 layouts is required |
| ON Semiconductor MBR1535CT | Identical electrical specs and ITO-220AB package; differs in marking, traceability, and AEC-Q101 availability (TSC offers H-suffix) | Drop-in replacement in most PCBs; TSC version includes UL recognition and halogen-free compound | Prefer MBRF1535CT for UL-certified systems or where halogen-free compliance is mandated |
Compared with VS-15CTQ035 and MBR1535CT, the MBRF1535CT uniquely combines dual common-cathode topology, UL recognition, and halogen-free construction in a single ITO-220AB package-enabling higher integration density and faster regulatory approval in industrial and medical-grade power supplies.

FAQ
What is the maximum junction temperature rating for the MBRF1535CT?
The MBRF1535CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version J2105). This rating allows reliable operation in high-ambient environments such as enclosed server power supplies or under-hood automotive applications. Derating curves confirm usable current capacity down to 10 A at 125°C case temperature. The MBRF1535CT must be mounted to a heatsink capable of maintaining TJ ≤ 150°C under worst-case load and ambient conditions.
Does the MBRF1535CT have AEC-Q101 qualification?
The base MBRF1535CT is not AEC-Q101 qualified, but Taiwan Semiconductor offers an AEC-Q101-qualified variant designated MBRF1535CTH ('H' suffix). This version undergoes full stress testing per AEC-Q101 Rev D, including HTGB, HTRB, and temperature cycling. The MBRF1535CTH shares identical electrical and thermal specifications with the standard MBRF1535CT and is available in the same ITO-220AB package with 50/tube packaging.
What is the forward voltage drop of the MBRF1535CT at full rated current?
The MBRF1535CT exhibits a maximum forward voltage (VF) of 0.84 V at IF = 15 A and TJ = 25°C, as specified in the Electrical Specifications table. At elevated temperature (TJ = 125°C), VF drops to 0.72 V due to Schottky diode physics. This low VF directly reduces conduction losses-e.g., 12.6 W vs. ~22.5 W for a 1.5 V silicon diode at 15 A-making the MBRF1535CT especially valuable in high-efficiency 12 V and 5 V output rails.
How is the pinout configured for the dual-diode structure in the MBRF1535CT?
The MBRF1535CT uses a common-cathode configuration: Pin 1 (metal tab) and Pin 2 are cathodes tied internally, while Pin 2 and Pin 3 serve as the two independent anodes. Correct orientation requires the tab (Pin 1) to be electrically connected to the system ground or output rail common point. This configuration enables dual-output rectification or interleaved operation without external cathode wiring. The MBRF1535CT pinout is standardized across ITO-220AB Schottky arrays and matches mechanical drawings in TSC's Package Outline Dimensions document.
Is the MBRF1535CT UL recognized, and what is the file number?
Yes, the MBRF1535CT is UL Recognized under File # E-326243, confirmed in the Mechanical Data section of the official Taiwan Semiconductor datasheet. This recognition covers flammability (UL 94V-0), electrical insulation, and construction compliance for end-product safety certification. UL recognition applies to the standard MBRF1535CT and MBRF1535CTH variants, and is maintained across all production lots. Designers may reference this file number during UL 62368-1 or UL 60950-1 certification audits.
