Product details
Overview
MBRF1535CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, rated for 15A average forward current, 35V repetitive peak reverse voltage, and 150A surge current. It delivers low forward voltage (0.84V at 15A, 25°C), operates up to 150°C junction temperature, and is used in automotive-grade DC/DC converters requiring high efficiency and robust overvoltage protection.
For engineers reviewing the MBRF1535CTH datasheet, MBRF1535CTH pinout, MBRF1535CTH application, or MBRF1535CTH equivalent, key selection criteria include its AEC-Q101 qualification, 3.5°C/W junction-to-case thermal resistance, guard ring–enabled overvoltage protection, and compatibility with high-reliability power conversion in constrained thermal environments.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 35V/15A diodes in a single ITO-220AB thermally optimized package. Its design emphasizes low conduction loss (VF = 0.72V at 15A, 125°C) and high transient surge capability (150A, 8.3ms half-sine), enabled by guard ring structure and matte tin-plated leads compliant with J-STD-002 solderability.
The device meets UL 94V-0 flammability rating, JESD201 Class 2 whisker resistance, and halogen-free compliance per IEC 61249-2-21 - all verified under AEC-Q101 stress testing for automotive under-hood applications.

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 ITO-220AB package, 35V VRRM, 15A IF, but not AEC-Q101 qualified; VF = 0.72V @ 15A, 125°C | Lacks automotive qualification; suitable for industrial/commercial SMPS only | Select when AEC-Q101 is not required and lower VF at high temperature is prioritized |
| ON Semiconductor MBR1535CT | Identical electrical specs and package; AEC-Q101 qualified version designated MBR1535CTG (not MBR1535CTH) | Same automotive use case, but different manufacturer's qualification documentation and traceability | Choose based on supply chain preference; verify qualification certificate alignment with OEM requirements |

FAQ
What does the "H" suffix in MBRF1535CTH signify?
The "H" suffix in MBRF1535CTH indicates full AEC-Q101 qualification per the Automotive Electronics Council stress test standard. This includes temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) testing - confirming suitability for automotive under-hood applications. The base part MBRF1535CT lacks this qualification, making MBRF1535CTH the only version approved for automotive use.
Is MBRF1535CTH pin-compatible with other MBRF15xxCT variants?
Yes, all MBRF15xxCT variants - including MBRF1535CTH, MBRF1545CTH, and MBRF15150CTH - share identical ITO-220AB package dimensions, pinout (dual anode/common cathode), and mechanical mounting interface. Voltage rating differences (35V to 150V) do not affect physical compatibility, enabling drop-in replacement during design iteration or BOM optimization.
What is the maximum allowable mounting torque for MBRF1535CTH?
The maximum recommended mounting torque for MBRF1535CTH is 0.56 N·m when securing the device to a heatsink using the insulated metal tab. Exceeding this value risks cracking the epoxy molding compound or damaging internal wire bonds. Proper torque ensures optimal thermal contact while preserving mechanical integrity and UL 94V-0 flammability compliance.
How does the guard ring feature improve reliability in MBRF1535CTH?
The guard ring in MBRF1535CTH mitigates edge breakdown under high electric field conditions by redistributing voltage stress away from the diode junction periphery. This extends operational life in applications with repetitive voltage transients - such as automotive load dump events - and improves consistency in reverse leakage (IR) performance across temperature and voltage stress, especially near the 35V VRRM limit.
Does MBRF1535CTH require derating at elevated ambient temperatures?
Yes, MBRF1535CTH requires current derating above 25°C ambient, per its forward current derating curve. At 100°C case temperature, the average forward current must be reduced to approximately 9.5A to maintain TJ ≤ 150°C. Derating is governed by the 3.5°C/W junction-to-case thermal resistance and system-level heatsinking capability - not ambient alone - so actual limits depend on thermal interface quality and heatsink design.
