Product details
Overview
MBR10L100CT from Taiwan Semiconductor is a 10A, 100V low forward-voltage dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.76V max VF at 10A/25°C, 120A IFSM surge rating, and AEC-Q101 qualification option (MBR10L100CTH). It serves as primary output rectifier in high-efficiency DC-DC converters and SMPS.
For engineers reviewing the MBR10L100CT datasheet, MBR10L100CT pinout, MBR10L100CT application, or MBR10L100CT equivalent, key selection criteria include its low conduction loss (0.71V max VF at 10A/125°C), 2.8°C/W junction-to-case thermal resistance, and dual-die configuration enabling common-cathode topology for synchronous rectification circuits.
Technical Context
The MBR10L100CT integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, supporting dual-output or center-tapped transformer topologies. Its guard ring structure provides enhanced dv/dt immunity (10,000 V/μs) and overvoltage robustness.
Designed for high-frequency switching applications, it delivers stable reverse leakage (<15 mA at 125°C) and maintains low forward voltage across temperature (0.66–0.71V at 10A/125°C), enabling improved efficiency in compact 50–500 kHz power supplies where thermal management is critical.

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-MBR10100CT | Same 10A/100V rating, 0.82V max VF at 10A/25°C; no AEC-Q101 variant offered | Lacks automotive qualification; suitable for commercial-grade adapters and industrial SMPS only | Select when AEC-Q101 is not required and Vishay supply chain preference applies |
| ON Semiconductor MBR10100CT | Identical electrical specs; TO-220AB package with different marking layout; 3.0°C/W RθJC (vs. 2.8°C/W) | Slightly higher thermal resistance may require marginally larger heatsink in thermally limited designs | Choose when ON Semi logistics alignment or existing qualification data drives sourcing |
Compared with MBR10L100CT, VS-MBR10100CT offers identical voltage/current ratings but lacks automotive qualification, while MBR10100CT trades 0.2°C/W higher thermal resistance for broader distributor availability-both require review of VF temperature coefficient and surge waveform compatibility for final design validation.

FAQ
What is the maximum forward voltage drop of the MBR10L100CT at full rated current and room temperature?
The MBR10L100CT has a maximum forward voltage (VF) of 0.76 V at 10 A and 25°C junction temperature, measured per diode under pulsed conditions (PW = 0.3 ms). This low VF value directly reduces conduction losses and improves overall system efficiency in high-current power conversion stages.
Does the MBR10L100CT support automotive-grade applications?
Yes-the MBR10L100CTH variant is explicitly qualified to AEC-Q101 standards for automotive use. While the base MBR10L100CT is not AEC-Q101 certified, its 150°C maximum junction temperature, guard ring protection, and JESD201 Class 2 whisker resistance make it suitable for industrial and extended-temperature applications where automotive qualification is not mandated.
How is the dual-die configuration of the MBR10L100CT implemented in the TO-220AB package?
The MBR10L100CT integrates two independent Schottky diodes sharing a common cathode terminal (Pin 2), with separate anodes on Pin 1 and Pin 3. This common-cathode arrangement supports dual-output flyback or center-tapped forward converter topologies without requiring external parallel diodes or additional routing.
What is the thermal resistance from junction to case for the MBR10L100CT, and how does it impact heatsink design?
The MBR10L100CT has a typical junction-to-case thermal resistance (RθJC) of 2.8°C/W. This value enables accurate calculation of required heatsink thermal resistance when combined with expected power dissipation (e.g., 10 A × 0.71 V ≈ 7.1 W at 125°C), allowing engineers to select appropriately sized aluminum heatsinks or direct-mount solutions without over-engineering.
Can the MBR10L100CT replace standard silicon rectifiers in existing 100V designs?
Yes-the MBR10L100CT can directly replace 10A/100V silicon rectifiers such as 1N5408 or UF1007 in most SMPS applications, provided layout accommodates TO-220AB footprint and thermal management accounts for lower VF (reduced heat) but higher reverse leakage at elevated temperatures. Always verify IR at operating TJ and dv/dt stability in the target circuit.
