Product details
Overview
MBR20100PT from Taiwan Semiconductor is a 20A, 100V dual-die Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.95V max forward voltage at 20A/25°C, 150A surge capability, and 1°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in high-frequency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR20100PT datasheet, MBR20100PT pinout, MBR20100PT application, or MBR20100PT equivalent, key selection criteria include repetitive peak reverse voltage (100V), forward current rating (20A), thermal resistance (1°C/W), AEC-Q101 qualification status, and TO-247AD mechanical compatibility.
Technical Context
This dual-die Schottky rectifier uses guard ring structure for overvoltage protection and supports high di/dt operation with 10,000 V/μs critical rate of rise of off-state voltage. Its low VF and low IR enable high efficiency in continuous conduction mode power stages.
Designed for surface-mount-compatible through-hole mounting, it operates across -55°C to +150°C junction temperature range and meets UL 94V-0 flammability and JESD201 Class 2 whisker requirements. Matte tin-plated leads ensure reliable solderability per J-STD-002.

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-20CPH10 | Same 20A/100V rating, TO-247AC package (non-isolated tab), 0.92V VF max at 20A/25°C | Lacks AEC-Q101 qualification; not validated for automotive temperature cycling | Select when cost sensitivity outweighs automotive qualification needs and thermal isolation is not required |
| ON Semiconductor MBR20100CT | Identical TO-220AB package pinout, 0.95V VF max, but only 10A per die (20A total shared), higher RθJC (2.5°C/W) | Lower thermal performance limits continuous operation above 15A without forced air | Select for legacy TO-220 layouts where board rework is prohibitive and power levels stay ≤15A |
Compared with VS-20CPH10 and MBR20100CT, the MBR20100PT offers superior thermal management (1°C/W vs. 2.5°C/W), AEC-Q101 availability, and electrically isolated tab-critical for grounded heatsink configurations in industrial and automotive designs.

FAQ
What is the maximum junction temperature rating for MBR20100PT?
The MBR20100PT has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This allows uninterrupted operation in enclosed industrial environments where case temperatures reach 100°C, provided thermal design maintains junction temperature below this limit. Derating curves in the datasheet confirm 20A operation up to 100°C case temperature.
Does MBR20100PT have an AEC-Q101 qualified version?
Yes, the MBR20100PTH variant is AEC-Q101 qualified, indicated by the "H" suffix in the ordering code. The base MBR20100PT is not automatically qualified; qualification applies only to parts marked and ordered as MBR20100PTH. This version undergoes extended temperature cycling, humidity testing, and mechanical stress validation for automotive under-hood use.
What is the forward voltage drop of MBR20100PT at 20A and 125°C?
The MBR20100PT exhibits a maximum forward voltage (VF) of 0.85V at 20A and TJ = 125°C, per electrical specifications table. This value is measured under pulse conditions (PW = 0.3ms) and reflects real-world performance in thermally stressed high-power converters where silicon diodes would exceed 1.2V.
How does the TO-247AD package of MBR20100PT differ from standard TO-247AC?
The TO-247AD (also labeled TO-3P) package used by MBR20100PT features an electrically isolated metal tab, unlike TO-247AC which has a conductive tab tied to the cathode. This isolation allows direct mounting to grounded heatsinks without insulation hardware, reducing thermal resistance and simplifying mechanical design in high-voltage industrial systems.
What is the reverse leakage current specification for MBR20100PT at rated voltage and high temperature?
At VR = 100V and TJ = 125°C, the MBR20100PT specifies a maximum reverse leakage current (IR) of 5 mA per diode, per electrical specifications. This low leakage ensures minimal standby power loss in always-on applications such as smart building controllers and network infrastructure equipment operating continuously at elevated ambient temperatures.
