Product details
Overview
MBRF1590CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, rated for 15A average forward current, 90V repetitive peak reverse voltage, and 150A surge current, delivering low forward voltage (0.92V typ. @ 7.5A, 25°C) for high-efficiency DC/DC converters and automotive power supplies.
For engineers reviewing the MBRF1590CTH datasheet, MBRF1590CTH pinout, MBRF1590CTH application, or MBRF1590CTH equivalent, key selection criteria include its 90V VRRM, 3.5°C/W junction-to-case thermal resistance, AEC-Q101 qualification, 100µA max reverse leakage at 25°C, and compatibility with high-surge, low-loss switching power topologies.
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package, enabling dual-channel rectification without external paralleling. Its guard ring structure provides overvoltage protection, and it supports 10,000 V/µs critical rate of rise of off-state voltage.
Designed for operation from –55°C to +150°C junction temperature, the MBRF1590CTH maintains stable forward voltage down to 0.82V @ 7.5A and 125°C, with reverse leakage limited to 5mA @ 125°C - critical for thermal reliability in compact, convection-cooled automotive and industrial SMPS designs.
Key Specifications

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-15MQ090 | Same ITO-220AB package, 90V VRRM, but 0.85V VF @ 7.5A (25°C); no AEC-Q101 qualification | Preferred for cost-sensitive industrial SMPS where automotive qualification is not required | Select when lower forward drop is prioritized over automotive reliability validation |
| ON Semiconductor MBR1590CT | Identical electrical specs and package, but lacks AEC-Q101 qualification and halogen-free compliance | Suitable for commercial-grade adapters and consumer power supplies | Choose when AEC-Q101 and green material compliance are not mandatory |
Compared with VS-15MQ090 and MBR1590CT, the MBRF1590CTH uniquely combines AEC-Q101 qualification, halogen-free construction, and guaranteed 90V blocking with industry-standard thermal performance - making it the only option qualified for automotive under-hood use without derating or additional validation.

FAQ
What is the maximum junction temperature rating for MBRF1590CTH?
The MBRF1590CTH has a maximum junction temperature (TJ) of +150°C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures without active cooling. The device's thermal design - including 3.5°C/W RθJC and ITO-220AB package - ensures that MBRF1590CTH stays within safe operating limits even at full 15A load under elevated ambient conditions.
Is MBRF1590CTH pin-compatible with non-AEC-Q101 versions like MBR1590CT?
Yes, MBRF1590CTH shares identical ITO-220AB mechanical dimensions, pinout, and terminal assignment with MBR1590CT and other members of the MBRF15xCT family. However, MBRF1590CTH includes additional AEC-Q101 qualification, halogen-free materials, and tighter process controls - meaning it can be used as a drop-in replacement where automotive reliability is required, but the reverse substitution is not recommended for AEC-Q101-compliant designs.
What is the forward voltage specification for MBRF1590CTH at 15A and 125°C?
The MBRF1590CTH does not specify forward voltage at 15A and 125°C in the official datasheet; only values at 7.5A are provided (0.82V typ.). At 15A and 25°C, typical VF is not published for MBRF1590CTH - unlike lower-voltage variants (e.g., MBRF1535CT). Engineers should apply derating curves from Figure 4 and verify conduction loss using the 7.5A data points and thermal modeling for full-load thermal design of MBRF1590CTH.
Does MBRF1590CTH meet UL safety standards?
Yes, MBRF1590CTH is UL Recognized under File #E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for power supply applications. This recognition covers flammability (UL 94V-0), terminal solderability (J-STD-002), and mechanical robustness - supporting end-equipment certification for adapters, industrial PSUs, and automotive ECUs without requiring additional component-level safety testing.
What is the reverse leakage current of MBRF1590CTH at rated voltage and 125°C?
At 90V reverse voltage and 125°C junction temperature, the MBRF1590CTH exhibits a maximum reverse leakage current (IR) of 5 mA per diode, as specified in the Electrical Specifications table. This value is confirmed across the full MBRF1590CT–MBRF15150CT series and reflects worst-case behavior under high-temperature stress - critical for evaluating standby power loss and thermal runaway risk in high-density power designs using MBRF1590CTH.
