Product details
Overview
MBRF1590CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 15 A average forward current, 90 V repetitive peak reverse voltage (VRRM), and 150 A surge current (IFSM). It operates up to 150°C junction temperature and delivers 0.92 V typical forward voltage at 7.5 A and 25°C, targeting high-efficiency DC/DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRF1590CT datasheet, MBRF1590CT pinout, MBRF1590CT application, or MBRF1590CT equivalent, key selection criteria include its 90 V VRRM rating, low VF at elevated temperature (0.82 V @ 7.5 A, 125°C), 3.5 °C/W junction-to-case thermal resistance, and AEC-Q101 qualification option - critical for automotive power modules and industrial adapters requiring robust thermal performance and reliability.
Technical Context
The MBRF1590CT integrates two independent Schottky diodes in a common-cathode configuration within a single ITO-220AB thermally enhanced package. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads meet J-STD-002 solderability standards and JESD201 Class 2 whisker resistance.
Designed for high-frequency switching applications, it supports dv/dt up to 10,000 V/µs and exhibits low reverse leakage (100 µA max @ 25°C, 90 V VR), with thermal derating enabling stable 15 A operation at case temperatures up to 85°C per the forward current derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or forward converter secondary circuits |
| IF(AV) | 15 A - continuous average forward current per diode; enables compact heatsink design in 100–300 W power supplies |
| IFSM | 150 A - non-repetitive surge capability; withstands inrush and transient overload without failure |
| VF @ 7.5A, 25°C | 0.92 V typ - low conduction loss directly reduces power dissipation and improves system efficiency |
| RθJC | 3.5 °C/W - low thermal resistance enables direct mounting to heatsink for effective junction temperature control |
| IR @ 90V, 25°C | 100 µA max - minimal leakage preserves efficiency in high-impedance bias networks and standby modes |
| TJ max | 150 °C - extended junction temperature rating supports operation in sealed or high-ambient environments |

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, 15 A / 90 V rating, but VF = 0.85 V @ 7.5 A (25°C); no AEC-Q101 option listed | Preferred where lower VF is prioritized over automotive qualification | Select VS-15MQ090 when optimizing for peak efficiency at room temperature in commercial adapters |
| ON Semiconductor MBR1590CT | Identical electrical specs and package; differs in marking, traceability, and internal die process - not AEC-Q101 qualified in standard grade | Suitable for industrial SMPS where automotive qualification is not required | Choose MBR1590CT for drop-in replacement in legacy ON Semi-based designs with identical thermal and layout constraints |
Compared with VS-15MQ090 and MBR1590CT, the MBRF1590CT offers verified AEC-Q101 qualification and tighter IR specification (100 µA max), making it the preferred choice for automotive and high-reliability industrial applications where leakage and qualification rigor are design-critical.

FAQ
What is the maximum junction temperature rating for MBRF1590CT?
The MBRF1590CT has a maximum junction temperature (TJ max) of +150°C, validated per absolute maximum ratings. This allows reliable operation in high-ambient environments such as enclosed server power supplies or under-hood automotive modules. Derating curves confirm 15 A continuous current is sustainable up to 85°C case temperature, with thermal management via the ITO-220AB package's 3.5 °C/W RθJC.
Is MBRF1590CT pin-compatible with other parts in the MBRF15xxCT family?
Yes, all MBRF15xxCT variants - including MBRF1535CT through MBRF15150CT - share identical ITO-220AB mechanical dimensions, pinout, and terminal configuration. The MBRF1590CT uses the same three-terminal layout (Anode 1 / Common Cathode / Anode 2), enabling direct substitution within the same voltage class when board space and thermal interface remain unchanged.
Does MBRF1590CT have AEC-Q101 qualification?
The base MBRF1590CT is not AEC-Q101 qualified; however, the AEC-Q101 variant is designated MBRF1590CTH per the ordering information. This H-suffix version undergoes full stress testing per AEC-Q101 Rev D, including temperature cycling, HTSL, and unbiased HAST, and is marked accordingly. Always verify suffix and packaging code when sourcing for automotive applications.
What is the typical forward voltage of MBRF1590CT at 15 A and 125°C?
The datasheet does not specify VF at 15 A and 125°C for MBRF1590CT. However, at 7.5 A and 125°C, VF is 0.82 V typical. Extrapolation is not recommended; design margin should be based on the 0.92 V typical value at 7.5 A/25°C and confirmed with thermal simulation. For 15 A operation at high temperature, consult the forward characteristics curve (Fig.4) and apply appropriate derating.
How is polarity marked on the MBRF1590CT device body?
Polarity on the MBRF1590CT is marked per the official marking diagram: the cathode is indicated by a wide band adjacent to Lead 1 (common cathode terminal), while the anodes correspond to the metal tab (Anode 1) and Lead 2 (Anode 2). The device also features laser-marked "MBRF1590CT" and date code (YWW format) on the front surface, with green compound (G) denoting halogen-free compliance.
