Product details
Overview
MBRF2590CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, rated for 25A average forward current, 90V repetitive peak reverse voltage, and 200A non-repetitive surge current; it delivers low forward voltage (0.85V typ. @ 12.5A, 25°C) and operates up to 150°C junction temperature, used in automotive-grade DC/DC converters and high-efficiency SMPS.
For engineers reviewing the MBRF2590CTH datasheet, MBRF2590CTH pinout, MBRF2590CTH application, or MBRF2590CTH equivalent, key selection criteria include its AEC-Q101 qualification, 90V VRRM, dual-common-cathode configuration, thermal resistance (RθJC = 1°C/W), and low leakage (100µA max @ 90V, 25°C).
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection, enabling synchronous rectification or dual-output configurations. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.
The MBRF2590CTH supports high-frequency switching with 10,000 V/µs critical dv/dt rating and maintains stable reverse leakage (<7.5 mA @ 90V, 125°C), making it suitable for demanding automotive power conversion where thermal management and reliability under transient stress are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in high-side or freewheeling positions. |
| IF | 25 A - Average forward current per diode at case temperature ≤75°C; enables compact heatsink design in 200W–300W power stages. |
| IFSM | 200 A - Peak non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients without failure. |
| VF | 0.85 V (typ) @ 12.5A, 25°C - Low conduction loss improves system efficiency by reducing power dissipation vs. silicon rectifiers. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for effective thermal path in space-constrained layouts. |
| IR | 100 µA (max) @ 90V, 25°C - Low reverse leakage minimizes standby power loss and improves reliability in high-temperature 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-25CPQ090PbF | Same ITO-220AB package, 25A/90V rating, but not AEC-Q101 qualified; VF = 0.78V (typ) @ 12.5A, 25°C. | Targeted at commercial/industrial use only; lacks automotive stress validation and whisker test compliance. | Select when AEC-Q101 is not required and lower forward voltage is prioritized over automotive qualification. |
| ON Semiconductor MBR2590CT | Identical electrical specs and package, but not AEC-Q101 qualified; RoHS-compliant, halogen-free, same pinout. | Approved for industrial and consumer power supplies; no automotive qualification documentation or test reports provided. | Choose for cost-sensitive non-automotive designs where qualification overhead is unnecessary and supply chain flexibility is valued. |
Compared with VS-25CPQ090PbF and MBR2590CT, the MBRF2590CTH uniquely combines AEC-Q101 qualification, guard ring protection, and verified 125°C leakage performance-making it the only option qualified for under-hood automotive power conversion without derating or additional system-level validation.

FAQ
What is the AEC-Q101 qualification status of MBRF2590CTH?
The MBRF2590CTH is fully AEC-Q101 qualified per Version L2105 documentation, including stress testing for temperature cycling, humidity bias, mechanical shock, and whisker growth (JESD201 Class 2). This qualification confirms suitability for automotive power modules, engine control units, and ADAS subsystems where reliability under harsh environmental conditions is critical. The "H" suffix in MBRF2590CTH explicitly denotes this certified qualification status.
Does MBRF2590CTH have a common-cathode or common-anode configuration?
The MBRF2590CTH uses a dual-diode common-cathode configuration: Pins 1 and 2 are independent anodes, and Pin 3 is the shared cathode. This layout supports dual-output rectification, interleaved topologies, or redundant paths in high-availability power systems. The marking diagram and absolute maximum ratings table in the official datasheet confirm this pin assignment for all MBRF25xCTH variants, including MBRF2590CTH.
What is the maximum junction temperature and thermal resistance of MBRF2590CTH?
The MBRF2590CTH has a maximum junction temperature (TJ) of +150°C and a junction-to-case thermal resistance (RθJC) of 1°C/W. These values are specified in the Thermal Performance section of the datasheet and enable reliable operation at full 25A load when mounted to an adequately sized heatsink. The low RθJC ensures minimal temperature rise across the die-to-tab interface, supporting compact thermal design in automotive and industrial applications.
How does the forward voltage of MBRF2590CTH compare at different temperatures and currents?
At 25°C junction temperature, MBRF2590CTH exhibits 0.85V typical forward voltage at 12.5A and 0.92V at 25A. At 125°C, those values drop to 0.75V and 0.88V respectively-demonstrating positive temperature coefficient behavior typical of Schottky diodes. These values are measured per datasheet conditions (pulse test, PW = 0.3ms) and are critical for accurate conduction loss calculation across operating temperature ranges.
Is MBRF2590CTH halogen-free and RoHS compliant?
Yes, MBRF2590CTH is both halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. The datasheet explicitly states compliance in the Features section and Mechanical Data table. These certifications are verified through material declarations and third-party testing, ensuring compatibility with lead-free assembly processes and environmentally regulated markets including automotive and industrial equipment sold in the EU and China.
