Product details
Overview
MBRS2590CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 90 V repetitive peak reverse voltage, and 200 A non-repetitive surge current; it delivers low forward voltage drop (0.85 V typ. @ 12.5 A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in compact DC/DC modules.
For engineers reviewing the MBRS2590CT datasheet, MBRS2590CT pinout, MBRS2590CT application, or MBRS2590CT equivalent, key selection criteria include its 90 V VRRM, dual-common-cathode configuration, 1.0 °C/W junction-to-case thermal resistance, and J-STD-020 Level 1 moisture sensitivity - all critical for SMPS output rectification under high thermal stress and automated SMT assembly.
Technical Context
The MBRS2590CT integrates two independent Schottky diodes in a single TO-263AB thermally optimized package with common cathode connection, supporting synchronous or parallel rectification topologies. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads ensure solderability per J-STD-002 and whisker resistance per JESD 201 Class 2.
Designed for high-frequency switching applications, it exhibits 10,000 V/μs critical rate of rise of off-state voltage and low reverse recovery charge due to majority-carrier conduction. At 125°C junction temperature, forward voltage remains 0.75 V (max) at 12.5 A, and reverse leakage is limited to 7.5 mA at rated 90 V - enabling stable operation in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum repetitive reverse blocking capability without breakdown, defining usable input/output voltage range in buck or flyback secondary-side rectification |
| IF | 25 A - continuous average forward current rating at case temperature ≤ 110°C, supporting high-power density converter designs |
| IFSM | 200 A - peak non-repetitive surge current (8.3 ms half-sine), enabling robustness against line transients and startup inrush |
| VF @ 12.5A, 25°C | 0.85 V (max) - low conduction loss per diode, directly reducing power dissipation and improving system efficiency |
| RθJC | 1.0 °C/W - thermal resistance from junction to case, allowing precise heatsink sizing when mounted on copper pour or external thermal pad |
| IR @ 90V, 125°C | 7.5 mA - controlled reverse leakage at max operating temperature, minimizing standby power loss in high-temp environments |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal outline with exposed thermal pad; case material meets UL 94V-0; polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first Schottky die | Connects to transformer secondary or switch node; requires trace width and copper area sufficient for 25 A continuous current |
| Pin 2 (Cathode) | Common cathode for both dies | Shared output node; must be routed to low-impedance ground/power plane with minimal inductance for EMI control |
| Pin 3 (Anode 2) | Anode of second Schottky die | Enables dual-output or interleaved rectification; electrically isolated from Anode 1 except through shared cathode |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Prevents premature avalanche failure during voltage transients, extending reliability in unregulated or loosely regulated supplies |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow, enabling direct placement into standard SMT lines without process modification |
| Dual-die common-cathode configuration | Reduces component count vs. discrete diodes; supports center-tapped transformer or dual-rail output rectification |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and global environmental regulations, supporting export-ready industrial and consumer product certifications |
Applications
| Switching Mode Power Supply (SMPS) | DC/DC Converter Module |

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 90 V VRRM, 25 A IF, TO-263AB package; slightly higher VF (0.88 V max @ 12.5 A, 25°C); RθJC = 1.2 °C/W | Identical use in SMPS secondary rectification; marginally lower thermal performance limits max continuous current in sealed enclosures | Preferred where Vishay qualification or long-term supply continuity is required; verify thermal margin in high-ambient designs |
| ON Semiconductor MBR2590CT | Same electrical ratings and TO-263AB footprint; differs in marking, minor process variation; VF spec identical (0.85 V max @ 12.5 A, 25°C) | Drop-in replacement in existing layouts; validated in automotive-grade reference designs with extended temperature screening | Recommended for AEC-Q101-compliant systems requiring automotive qualification; no PCB change needed if footprint matches |
Compared with VS-25CPQ090PbF, MBRS2590CT offers better thermal resistance and lower forward voltage; compared with MBR2590CT, it lacks AEC-Q101 qualification but provides identical electrical performance and cost advantage in industrial applications.

FAQ
What is the maximum junction temperature rating for MBRS2590CT?
The MBRS2590CT has a maximum junction temperature (TJ) of +150°C, verified across its full operating range. This rating enables reliable operation in high-temperature environments such as enclosed power supplies or motor drive auxiliary rails. Derating curves in the official datasheet specify that average forward current must be reduced to 18 A at 125°C case temperature to maintain safe thermal margins. The device's 1.0 °C/W RθJC supports effective heat transfer when mounted on ≥2 oz copper with thermal vias.
Does MBRS2590CT have a common-cathode or common-anode configuration?
The MBRS2590CT uses a common-cathode configuration: Pin 2 is the shared cathode terminal, while Pins 1 and 3 serve as independent anodes for the two internal Schottky dies. This arrangement is explicitly confirmed in the package marking diagram and absolute maximum ratings table. It supports center-tapped transformer rectification, dual-output DC/DC converters, and interleaved designs without external wiring. Layout must route the cathode pin to a low-inductance ground/power plane to minimize EMI.
What is the forward voltage specification for MBRS2590CT at full rated current?
At 25 A average forward current and 25°C junction temperature, the MBRS2590CT has a maximum forward voltage (VF) of 0.92 V per diode, as specified in the Electrical Specifications table. This value increases to 0.88 V at 125°C. The typical VF is lower (0.85 V @ 12.5 A, 25°C), but design calculations must use the max value for worst-case power loss estimation: PLOSS = 0.92 V × 25 A = 23 W per diode, requiring appropriate thermal management.
Is MBRS2590CT suitable for use in automotive applications?
The MBRS2590CT is not AEC-Q101 qualified and is not recommended for automotive safety-critical or engine-compartment applications. While it operates from –55°C to +150°C and meets RoHS/halogen-free standards, Taiwan Semiconductor does not list it in their automotive-grade product portfolio. For automotive use, consider the functionally equivalent ON Semiconductor MBR2590CT, which carries AEC-Q101 certification and extended reliability testing. MBRS2590CT remains appropriate for industrial and consumer power supplies with similar thermal and electrical requirements.
What packaging and moisture sensitivity level does MBRS2590CT ship in?
MBRS2590CT ships in TO-263AB (D2PAK) package on 800-unit tape-and-reel format, per the Ordering Information section. Its moisture sensitivity level (MSL) is Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking before SMT reflow. This simplifies manufacturing logistics and eliminates pre-reflow handling steps. The matte tin-plated leads comply with J-STD-002 for solderability, and the compound meets UL 94V-0 flammability rating.
