Product details
Overview
MBR2590CTH from Taiwan Semiconductor is a 25A, 90V dual-die Schottky barrier rectifier in TO-220AB package, featuring low forward voltage (0.85V at 12.5A/25°C), high surge capability (200A IFSM), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR2590CTH datasheet, MBR2590CTH pinout, MBR2590CTH application, or MBR2590CTH equivalent, key selection criteria include its 90V VRRM rating, 0.85V/0.92V forward voltage at 12.5A/25A (25°C), 7.5mA reverse leakage at 125°C, 1°C/W junction-to-case thermal resistance, and AEC-Q101 qualification status.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-220AB package with common cathode configuration. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads ensure solderability per J-STD-002.
The device operates across -55°C to +150°C junction temperature range and supports repetitive dv/dt up to 10,000 V/μs. Thermal performance is characterized by 1°C/W RθJC, enabling direct heatsink mounting for high-power dissipation in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse voltage; defines safe blocking capability in high-side switch-mode topologies |
| IF | 25 A - Continuous average forward current; supports high-output-current DC-DC stages without forced air cooling |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients in power supplies |
| VF @ 12.5A, 25°C | 0.85 V - Low conduction loss per diode; reduces power dissipation and improves system efficiency |
| IR @ 90V, 125°C | 7.5 mA - Reverse leakage under worst-case thermal stress; critical for standby power and thermal runaway margin |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; enables predictable thermal design with standard TO-220 heatsinks |
Pinout & Package
Package: TO-220AB, 3-terminal molded plastic case with isolated tab (cathode-connected tab), UL 94V-0 rated compound, matte tin-plated leads, polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |

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-MBR2590CTH | Identical 90V VRRM, 25A IF, TO-220AB package; VF = 0.86V @ 12.5A (25°C); AEC-Q101 qualified | No functional difference; validated in same automotive power modules | Select for multi-source procurement or regional inventory availability |
| ON Semiconductor MBR2590CT | Lacks AEC-Q101 qualification; otherwise matches VRRM, IF, VF, and package; RoHS compliant but not halogen-free | Restricted to non-automotive industrial use due to qualification gap | Choose only when AEC-Q101 is not required and cost sensitivity outweighs qualification assurance |
Compared with MBR2590CTH, VS-MBR2590CTH offers identical electrical and qualification specs for seamless dual-sourcing, while MBR2590CT trades AEC-Q101 compliance for lower cost in non-automotive applications-making MBR2590CTH the sole choice where automotive reliability is mandatory.

FAQ
What is the maximum junction temperature rating for MBR2590CTH?
The MBR2590CTH has a maximum junction temperature (TJ) of +150°C, with operational range from -55°C to +150°C. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures. The device's 1°C/W junction-to-case thermal resistance allows effective heat transfer to external heatsinks, maintaining safe junction temperatures even at full 25A continuous current when properly mounted.
Is MBR2590CTH pin-compatible with non-AEC-Q101 versions like MBR2590CT?
Yes, MBR2590CTH is mechanically and electrically pin-compatible with MBR2590CT - both use TO-220AB package with identical pinout (common cathode tab, Anode 1, Anode 2). However, MBR2590CTH includes AEC-Q101 qualification testing and halogen-free construction, while MBR2590CT does not. No PCB changes are required for substitution, but qualification status must be verified per application requirements.
What is the forward voltage specification for MBR2590CTH at full rated current?
At 25A forward current and 25°C junction temperature, the MBR2590CTH exhibits a typical forward voltage (VF) of 0.92V per diode. At elevated temperature (125°C), VF drops to 0.88V due to Schottky's negative temperature coefficient - a key advantage for thermal stability in high-power applications. These values are measured under pulsed conditions per datasheet test conditions.
Does MBR2590CTH support common-cathode dual-output configurations?
Yes, MBR2590CTH integrates two independent Schottky dies sharing a common cathode connection via the metal tab. This configuration directly supports dual-output DC-DC converters, interleaved rectification, or redundancy schemes without external wiring. Each anode (Terminals 2 and 3) operates independently, allowing separate transformer secondaries or split-phase windings to feed distinct output rails.
How does the guard ring feature improve reliability in MBR2590CTH?
The guard ring in MBR2590CTH is a diffusion-based structural enhancement surrounding the active Schottky junction. It mitigates edge breakdown under high dv/dt or transient overvoltage events - such as load dump or inductive kickback - by distributing electric field stress away from the junction periphery. This increases ruggedness without compromising forward conduction performance, extending lifetime in automotive and industrial power systems.
