Product details
Overview
MBR20200PTH from Taiwan Semiconductor is a 20A, 200V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD package, featuring 1.02V max forward voltage at 20A/25°C, 0.98V at 20A/125°C, and 5mA max reverse leakage at 200V/125°C. It delivers high surge current capability (150A IFSM), low thermal resistance (1°C/W RθJC), and is used in high-efficiency DC-DC converters and automotive-grade SMPS.
For engineers reviewing the MBR20200PTH datasheet, MBR20200PTH pinout, MBR20200PTH application, or MBR20200PTH equivalent, key selection criteria include peak reverse voltage rating, forward voltage vs. temperature behavior, junction-to-case thermal resistance, AEC-Q101 qualification status, and TO-247AD mounting torque limits (1.13 N·m max).
Technical Context
This device implements a dual-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 200V VRRM rating enables use in 48V–100V bus-derived power stages, while the 150A IFSM supports transient load demands in industrial and automotive DC-DC modules.
The 1°C/W RθJC and -55°C to +150°C TJ operating range allow direct heatsink mounting in thermally constrained environments. With 10,000 V/μs dV/dt rating and UL Recognized File #E-326243, it meets safety-critical requirements for isolated secondary-side rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; defines maximum DC bus or output voltage it can block reliably |
| IF | 20 A - Continuous forward current rating; determines minimum heatsink sizing for steady-state conduction loss |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); supports inrush and fault-current handling without failure |
| VF @ 20A/25°C | 1.02 V max - Directly impacts conduction loss (P = IF × VF) and thermal design at room temperature |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; enables accurate case temperature prediction when mounted to heatsink |
| IR @ 200V/125°C | 5 mA max - Reverse leakage at max rated voltage and junction temperature; affects standby power and thermal runaway risk |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for thermal management margin |
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-20CPH02-M3 | 200V VRRM, 1.05V VF @ 20A/25°C, TO-247AC package, no AEC-Q101 qualification | Non-automotive industrial use only; lacks automotive stress validation | Select when AEC-Q101 is not required and UL recognition is secondary |
| ON Semiconductor MBR20200CT | 200V VRRM, dual common-cathode configuration, TO-220AB package, 1.1V VF @ 20A/25°C | Limited to lower-power designs due to higher RθJC (~2.5°C/W) and lower IFSM (120A) | Select for cost-sensitive, non-automotive applications where TO-220 footprint and lower surge tolerance are acceptable |
Compared with VS-20CPH02-M3 and MBR20200CT, the MBR20200PTH provides verified AEC-Q101 compliance, superior thermal performance (1°C/W vs. ≥2.5°C/W), and higher surge robustness (150A vs. ≤120A), making it the preferred choice for automotive and high-reliability industrial rectification where thermal headroom and qualification traceability are critical.

FAQ
What is the maximum junction temperature rating for MBR20200PTH?
The MBR20200PTH has a maximum junction temperature (TJ max) of +150°C, validated across its full operating range from -55°C to +150°C. This rating is critical for thermal design in automotive underhood environments and high-ambient industrial applications. The device's 1°C/W RθJC enables accurate junction temperature calculation using measured case temperature. Derating curves in the official datasheet confirm continuous 20A operation up to 125°C case temperature.
Is MBR20200PTH pin-compatible with standard TO-247AD rectifiers?
Yes, MBR20200PTH uses the industry-standard TO-247AD (TO-3P) outline with three terminals: anode (lead 1), cathode (lead 2), and electrically connected case/tab (lead 3). Its pinout matches all TO-247AD-packaged Schottky and fast recovery rectifiers, including mechanical mounting hole positions and lead pitch. Mounting torque must not exceed 1.13 N·m to avoid package damage.
Does MBR20200PTH meet automotive qualification standards?
Yes, the "H" suffix in MBR20200PTH explicitly denotes AEC-Q101 qualification. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per JEDEC standards. The device also carries UL Recognition File #E-326243 and complies with RoHS and halogen-free requirements per IEC 61249-2-21 - all documented in Taiwan Semiconductor's official datasheet revision H2103.
What is the forward voltage specification for MBR20200PTH at elevated temperature?
At 20A and 125°C junction temperature, the MBR20200PTH has a maximum forward voltage (VF) of 0.98V. This value is confirmed in the Electrical Specifications table of the datasheet and reflects real-world performance under thermal stress. The 0.98V VF at 125°C is 4% lower than typical 150V-class Schottkys, contributing directly to reduced conduction loss and improved efficiency in high-temperature operation.
How does the guard ring feature improve reliability in MBR20200PTH?
The guard ring in MBR20200PTH prevents premature avalanche breakdown at the silicon periphery under high electric field conditions. This structural enhancement increases ruggedness against voltage transients, PCB surface contamination, and localized thermal gradients. In practice, it extends operational life in automotive applications exposed to load dump or jump-start surges, and improves yield in high-humidity industrial environments where creepage degradation could otherwise occur.
