Product details
Overview
MBR2590CT from Taiwan Semiconductor is a 25A, 90V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.85V forward voltage at 12.5A/25°C and 7.5mA reverse leakage at 125°C, optimized for high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR2590CT datasheet, MBR2590CT pinout, MBR2590CT application, or MBR2590CT equivalent, key selection criteria include repetitive peak reverse voltage (90V), surge current rating (200A), junction-to-case thermal resistance (1°C/W), and AEC-Q101 qualification availability in variant MBR2590CTH.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-220AB thermally enhanced package, enabling shared heatsinking for high-current dual-output or bridge configurations. Its guard ring structure provides overvoltage protection, and low VF supports efficiency-critical switching topologies.
The device operates across –55°C to +150°C junction temperature range with 10,000 V/μs critical dv/dt rating, supporting fast-switching applications where reverse recovery time is effectively zero-eliminating switching losses inherent in PN-junction rectifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or boost output stages |
| IF | 25 A - Continuous average forward current per diode; enables compact thermal design in 200W+ power supplies |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients without failure |
| VF @ 12.5A/25°C | 0.85 V - Low conduction loss per diode; reduces power dissipation by ~21% vs. comparable 100V Si diodes |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for stable 150°C operation at full load |
| IR @ 90V/125°C | 7.5 mA - Reverse leakage per diode; limits standby loss in high-temperature industrial environments |
Pinout & Package
TO-220AB package with center-tab cathode configuration: Pin 1 (left lead) = Anode 1, Pin 2 (center tab) = Cathode (common), Pin 3 (right lead) = Anode 2. Matte tin-plated leads comply with J-STD-002 solderability; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left Lead) | Anode of Diode 1 | Input node for first rectification path; electrically isolated from Pin 3 |
| Pin 2 (Center Tab) | Common Cathode | Thermally and electrically common output node; must be mounted to heatsink for thermal management |
| Pin 3 (Right Lead) | Anode of Diode 2 | Input node for second rectification path; enables dual-output or full-wave center-tap configuration |
Key Features

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 25A/90V rating, but single-die TO-247AC package; RθJC = 1.2°C/W; VF = 0.82V @ 12.5A/25°C | Lacks dual-anode integration; requires two devices for dual-output use; higher thermal resistance limits power density | Select when single-diode topology suffices and TO-247 mechanical fit is required |
| ON Semiconductor MBR2590CT | Identical electrical specs and TO-220AB package; same dual-die construction; VF = 0.85V @ 12.5A/25°C; IR = 7.5mA @ 90V/125°C | No functional difference; pinout and thermal profile match exactly; not AEC-Q101 qualified in standard grade | Select for cross-manufacturer sourcing continuity where Taiwan Semiconductor supply is constrained |
Compared with VS-25CPQ090PbF and ON Semiconductor's MBR2590CT, the Taiwan Semiconductor MBR2590CT uniquely delivers dual-anode integration in TO-220AB with 1°C/W thermal resistance-enabling higher power density and simplified dual-rail designs without sacrificing surge robustness or high-temperature leakage performance.

FAQ
What is the maximum junction temperature rating for MBR2590CT?
The MBR2590CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table. This rating enables continuous operation in high-ambient industrial environments when mounted to a heatsink with adequate thermal interface. Derating curves confirm 25A operation is sustainable up to 100°C case temperature. The MBR2590CT must not exceed this limit to maintain reliability and avoid parametric shift.
Does MBR2590CT have AEC-Q101 qualification?
The standard MBR2590CT is not AEC-Q101 qualified; however, the variant MBR2590CTH is explicitly listed in the ordering information as AEC-Q101 qualified. This distinction is marked by the "H" suffix and applies only to that specific ordering code. The MBR2590CT itself meets all electrical and thermal specifications but lacks the extended stress testing required for automotive under-hood applications.
What is the forward voltage of MBR2590CT at full rated current?
At 25A and 25°C junction temperature, the MBR2590CT exhibits a maximum forward voltage of 0.92V per diode, as specified in the electrical characteristics table. At 125°C, this increases to 0.88V due to negative temperature coefficient behavior typical of Schottky diodes. These values are measured under pulsed conditions with 0.3ms pulse width and are critical for conduction loss calculation in MBR2590CT-based designs.
Can MBR2590CT replace MBR25100CT in a 100V design?
No-MBR2590CT has a 90V repetitive peak reverse voltage (VRRM), while MBR25100CT is rated for 100V. Using MBR2590CT in a 100V application risks avalanche breakdown during transients or line surges. The datasheet specifies strict voltage binning per part number; MBR2590CT is not tested or guaranteed beyond 90V. For 100V designs, MBR25100CT or MBR25150CT must be used instead of MBR2590CT.
What is the thermal resistance from junction to case for MBR2590CT?
The junction-to-case thermal resistance (RθJC) of MBR2590CT is 1°C/W, as confirmed in the Thermal Performance section. This value is measured under standardized JEDEC conditions and applies to the TO-220AB package with proper mounting torque (≤0.56 N·m). It enables accurate thermal modeling when the center tab is attached to a heatsink, directly impacting maximum allowable power dissipation in MBR2590CT applications.
