Product details
Overview
MBR40200PT from Taiwan Semiconductor is a 40A, 200V dual-die Schottky barrier rectifier in TO-247AD package, featuring 1.01V max forward voltage at 40A/25°C and 100µA max reverse leakage at rated VR/25°C, designed for high-efficiency DC–DC converters and industrial SMPS.
For engineers reviewing the MBR40200PT datasheet, MBR40200PT pinout, MBR40200PT application, or MBR40200PT equivalent, key selection criteria include repetitive peak reverse voltage (200V), surge current capability (330A), thermal resistance (1.2°C/W), AEC-Q101 qualification status, and TO-247AD mechanical compatibility.
Technical Context
This dual-die Schottky rectifier integrates two independent 200V/40A diodes in a single TO-247AD package with common cathode configuration, enabling synchronous rectification or parallel operation in high-current outputs. Its guard ring structure provides overvoltage protection, and the 10,000 V/μs dV/dt rating supports fast-switching topologies.
The device operates across –55°C to +150°C junction temperature range, with 1.2°C/W junction-to-case thermal resistance enabling high-power dissipation when mounted on heatsinks. Reverse leakage remains ≤100 µA at 200V/25°C and ≤10 mA at 200V/125°C, supporting stable performance in thermally demanding 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-40CPH20 | Same 40A/200V rating, TO-247AC package, 1.05V VF max @ 40A/25°C, no AEC-Q101 option | Lacks guard ring; lower dV/dt (5,000 V/μs) limits use in fast-switching GaN-based designs | Preferred where cost sensitivity outweighs automotive qualification or transient robustness |
| ON Semiconductor MBR40200CT | Identical electrical specs, TO-247AC package, 1.01V VF max, AEC-Q101 available (MBR40200CTH) | Same pinout but different marking and internal die construction; validated for medical-grade isolation creepage | Recommended when regulatory documentation traceability (ISO 13485) is required for Class II medical systems |
Compared with VS-40CPH20 and MBR40200CT, the MBR40200PT offers superior transient immunity via its guard ring and higher dV/dt rating, while maintaining identical thermal and conduction performance-making it optimal for ruggedized industrial and transportation power systems.

FAQ
What is the maximum junction temperature rating for the MBR40200PT?
The MBR40200PT has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows sustained operation in sealed industrial enclosures or high-ambient environments when properly heatsinked. Derating curves confirm usable current capacity down to 25A at 125°C case temperature. The MBR40200PT must not exceed this limit to maintain long-term reliability and avoid parametric shift.
Does the MBR40200PT have AEC-Q101 qualification?
The base MBR40200PT is not AEC-Q101 qualified; however, the variant MBR40200PTH is explicitly certified per AEC-Q101 Rev D for automotive under-hood applications. Qualification includes stress testing for temperature cycling, humidity bias, and mechanical shock. For non-automotive use, the standard MBR40200PT delivers identical electrical performance and thermal characteristics as the qualified version.
What is the forward voltage drop of the MBR40200PT at full rated current?
The MBR40200PT exhibits a maximum forward voltage (VF) of 1.01 V at 40 A and 25°C junction temperature, as specified in the electrical characteristics table. At elevated temperatures (125°C), VF drops to 0.80 V due to Schottky physics. This low conduction loss directly reduces power dissipation-enabling 33 W max at 40 A-critical for high-density power designs using the MBR40200PT.
How does the MBR40200PT compare to silicon rectifiers in terms of efficiency?
The MBR40200PT achieves significantly higher efficiency than equivalent 200V silicon rectifiers due to its Schottky architecture: zero minority-carrier storage time eliminates reverse recovery loss, and its 1.01 V VF is ~40% lower than typical 200V Si diodes (~1.7 V). In a 48 V output, 40 A SMPS, this translates to ~28 W less conduction loss and up to 2.3% higher full-load efficiency versus silicon alternatives-directly reducing heatsink size and system cooling requirements for the MBR40200PT.
What is the thermal resistance from junction to case for the MBR40200PT?
The MBR40200PT has a junction-to-case thermal resistance (RθJC) of 1.2°C/W, measured under standard test conditions per JESD51-14. This value is critical for calculating allowable power dissipation: at 40 A and 1.01 V VF, the MBR40200PT dissipates ~40.4 W, requiring a heatsink that maintains case temperature ≤117°C to stay within the +150°C TJ limit. Mounting torque must not exceed 1.13 N·m to preserve thermal interface integrity.
