Product details
Overview
MBR40200PTH from Taiwan Semiconductor is a 40A, 200V AEC-Q101 qualified Schottky barrier rectifier in TO-247AD package, featuring 1.01V max forward voltage at 40A/25°C, 100µA max reverse current at 200V/25°C, and 330A surge capability-used in high-efficiency DC-DC converters and automotive-grade SMPS.
For engineers reviewing the MBR40200PTH datasheet, MBR40200PTH pinout, MBR40200PTH application, or MBR40200PTH equivalent, key selection criteria include junction-to-case thermal resistance (1.2°C/W), dual-die configuration, guard ring overvoltage protection, UL recognition (E-326243), and halogen-free compliance per IEC 61249-2-21.
Technical Context
This device implements a dual-die Schottky structure with guard ring for enhanced transient overvoltage immunity and operates across -55°C to +150°C junction temperature range. Its low VF and high IFSM support high-frequency switching topologies requiring minimal conduction loss and robust surge handling.
The TO-247AD package enables direct heatsink mounting with 1.13 N·m max torque, while matte tin-plated leads ensure J-STD-002 solderability and JESD 201 Class 2 whisker resistance-critical for automotive and industrial power conversion reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; defines maximum DC or peak AC blocking capability in rectifier applications |
| IF | 40 A - Continuous average forward current; determines steady-state power handling without derating at 25°C ambient |
| IFSM | 330 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance in SMPS input stages |
| VF @ 40A/25°C | 1.01 V max - Forward voltage drop; directly impacts conduction loss (P = IF × VF) and thermal design in high-current paths |
| IR @ 200V/25°C | 100 µA max - Reverse leakage current; critical for low-power standby efficiency and voltage hold-up stability |
| RθJC | 1.2 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing for 40A operation at TJ ≤ 150°C |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for thermal management in enclosed or high-ambient environments |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal single-diode configuration with anode, cathode, and case (electrically connected to cathode). Mounting hole centered on case flange; polarity marked on top surface.

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-MBR40200CT | TO-247AC package; 1.05V VF max @ 40A/25°C; 150µA IR @ 200V/25°C | Slightly higher conduction loss and leakage; same surge rating (330A) | Acceptable where minor efficiency trade-off is acceptable and TO-247AC footprint is preferred |
| ON Semiconductor MBR40200CT | TO-247AC package; 1.03V VF max @ 40A/25°C; 200µA IR @ 200V/25°C | Higher leakage limits use in low-standby-power designs; identical thermal resistance | Consider only for non-critical industrial applications where AEC-Q101 is not required |
Compared with MBR40200PTH, both alternatives lack AEC-Q101 qualification and exhibit higher VF or IR-making MBR40200PTH preferable for automotive and high-reliability industrial systems where low leakage, tight thermal control, and automotive-grade validation are mandatory.

FAQ
What is the maximum junction temperature rating for MBR40200PTH?
The MBR40200PTH has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows operation in high-ambient environments such as engine compartments or sealed industrial enclosures, provided thermal design maintains junction temperature below this limit using the specified 1.2°C/W RθJC path.
Is MBR40200PTH pin-compatible with TO-247AC packaged rectifiers?
No, MBR40200PTH uses the TO-247AD (TO-3P) package, which has different lead spacing and case geometry than TO-247AC. While both are 3-lead through-hole packages, mechanical mounting holes and terminal positions differ-requiring PCB layout revision for substitution. Always verify land pattern compatibility before replacement.
Does MBR40200PTH include a guard ring, and what function does it serve?
Yes, MBR40200PTH incorporates a guard ring structure explicitly stated in its features. This design enhances dv/dt immunity to 10,000 V/μs, preventing localized electric field concentration and premature avalanche breakdown during fast voltage transients-critical in high-frequency switching power supplies and automotive load-dump scenarios.
What is the reverse leakage current specification for MBR40200PTH at elevated temperature?
At 200V reverse voltage and 125°C junction temperature, MBR40200PTH specifies a maximum reverse leakage current (IR) of 10 mA. This value is confirmed in the Electrical Specifications table and directly impacts standby power loss and thermal runaway risk in high-temperature applications such as telecom rectifiers or motor drive snubbers.
How does the "H" suffix in MBR40200PTH indicate qualification status?
The "H" suffix in MBR40200PTH denotes AEC-Q101 qualification, as defined in the Ordering Information section of the datasheet. This means the device has undergone stress testing-including HTSL, TC, AC, and UHAST-to validate reliability for automotive power electronics, distinguishing it from the non-H variant MBR40200PT intended for commercial applications.
