Product details
Overview
MBR4090PTH from Taiwan Semiconductor is a 40A, 90V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD package, featuring 0.84V max forward voltage at 20A/25°C, 10mA max reverse current at 125°C, and 330A surge capability-designed for high-efficiency DC/DC converters in automotive power systems.
For engineers reviewing the MBR4090PTH datasheet, MBR4090PTH pinout, MBR4090PTH application, or MBR4090PTH equivalent, key selection criteria include its 90V VRRM, dual-die thermal performance (RθJC = 1.2°C/W), AEC-Q101 qualification, and TO-247AD mechanical compatibility with high-power heatsink mounting.
Technical Context
This device implements a dual-die Schottky architecture optimized for low conduction loss in high-current switching topologies. Its 90V repetitive peak reverse voltage and 10,000 V/μs dV/dt rating support robust operation in noisy automotive transients.
Thermal design is enabled by a 1.2°C/W junction-to-case resistance and 150°C maximum junction temperature, while the guard ring structure provides intrinsic overvoltage protection without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 90 V - Maximum blocking voltage before avalanche; defines usable input range in 48V–72V DC/DC stages |
| IF | 40 A - Continuous forward current rating; supports high-output SMPS designs without forced air cooling |
| IFSM | 330 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients in automotive ECUs |
| VF @ 20A, 25°C | 0.84 V max - Low conduction loss enables >94% efficiency in 12V–48V buck converters |
| IR @ 90V, 125°C | 10 mA max - Controlled leakage ensures stable biasing in high-temp under-hood environments |
| RθJC | 1.2 °C/W - Enables direct heatsink mounting with predictable thermal rise under full load |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package

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-MBR4090CT | Same 40A/90V rating, TO-247AC package (non-isolated case), 0.82V VF typ at 20A/25°C | Lacks AEC-Q101 qualification; not validated for automotive temperature cycling or HTRB | Select when cost sensitivity outweighs automotive qualification requirements |
| ON Semiconductor MBR4090CT | TO-247AC package, 0.85V VF max at 20A/25°C, 12mA IR at 125°C | No guard ring; lower dV/dt (5,000 V/μs); not UL recognized | Acceptable for industrial SMPS where transient immunity and safety certification are secondary |
Compared with MBR4090PTH, VS-MBR4090CT offers slightly lower forward drop but omits automotive qualification and isolation, while MBR4090CT trades off transient robustness and safety compliance for broader commercial availability.

FAQ
What is the maximum junction temperature rating for the MBR4090PTH?
The MBR4090PTH has a maximum junction temperature (TJ) of +150°C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-power industrial enclosures when mounted on appropriate heatsinks with RθJC = 1.2°C/W.
Does the MBR4090PTH have AEC-Q101 qualification?
Yes, the MBR4090PTH is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documented in Taiwan Semiconductor's I2103 datasheet revision. This includes validation for temperature cycling, high-temperature reverse bias, and electrostatic discharge per automotive reliability standards.
What does the "H" suffix in MBR4090PTH signify?
The "H" suffix in MBR4090PTH indicates AEC-Q101 qualification, distinguishing it from the non-automotive MBR4090PT variant. Per Taiwan Semiconductor's ordering information, "H" denotes full automotive-grade reliability testing and traceability, not just packaging or marking differences.
How does the dual-die configuration of the MBR4090PTH affect PCB layout?
The MBR4090PTH's dual-die configuration uses separate anode terminals (Anode 1 and Anode 2) sharing a common cathode. This requires independent high-current traces from each anode to respective power stages, avoiding shared impedance that could unbalance current distribution between dies during dynamic load steps.
Is the MBR4090PTH UL Recognized, and what is its file number?
Yes, the MBR4090PTH is UL Recognized under File #E-326243, as stated in the official datasheet. This certification applies to the TO-247AD package construction and confirms compliance with UL 94V-0 flammability requirements for use in safety-critical power supplies.
