Product details
Overview
MBR20100CT-Y from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-220AB package with 100V repetitive peak reverse voltage (VRRM), 0.85V typical forward voltage at 10A/25°C, and 150A surge current capability - used in high-efficiency DC-DC converters and switching power supplies where low conduction loss and fast recovery are critical.
For engineers reviewing the MBR20100CT-Y datasheet, MBR20100CT-Y pinout, MBR20100CT-Y application, or MBR20100CT-Y equivalent, key selection criteria include VRRM=100V, IF=20A continuous, RθJC=2°C/W thermal resistance, TJ max=150°C, and TO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 20A diodes in a single TO-220AB case, enabling synchronous or parallel operation in center-tapped or dual-output topologies. Its guard ring structure provides overvoltage protection, and it meets JESD201 Class 1A whisker resistance.
Designed for high-frequency switching applications, it delivers low forward voltage (VF ≤ 0.95V at 20A/25°C) and low reverse leakage (IR ≤ 5mA at 100V/125°C), with dv/dt rating of 10,000 V/μs ensuring robustness against voltage transients in SMPS circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in buck or flyback designs. |
| IF (continuous) | 20 A - Average forward current per diode at TC = 100°C; supports high-power output stages without forced air cooling. |
| IFSM (8.3ms) | 150 A - Peak non-repetitive surge current tolerance; handles inrush and transient overload without failure. |
| VF @ 10A/25°C | 0.85 V - Low conduction loss per diode; reduces power dissipation and improves system efficiency above 90% in 12–48V DC-DC converters. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance for MBR20100CT-Y variant; enables thermal design with standard TO-220 heatsinks. |
| IR @ 100V/125°C | 5 mA - Reverse leakage per diode at rated voltage and elevated temperature; limits standby power loss in high-temp environments. |
| TJ max | 150 °C - Maximum junction temperature; allows operation in industrial ambient up to 85°C with appropriate derating. |

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-MBR20100CT | VRRM=100V, IF=20A, VF=0.87V @ 20A/25°C, RθJC=2.0°C/W, same TO-220AB package. | No green compound marking; halogen-free status not explicitly declared in latest datasheet revision. | Drop-in replacement where RoHS/halogen-free compliance is not mandated; verify date-code traceability for long-term supply. |
| ON Semiconductor MBR20100CT | VRRM=100V, IF=20A, VF=0.89V @ 20A/25°C, RθJC=2.2°C/W, TO-220AB, RoHS compliant. | Higher RθJC increases thermal margin requirement; IR=10mA @ 100V/125°C - 2× higher leakage than MBR20100CT-Y. | Suitable when cost sensitivity outweighs thermal or leakage performance; requires minor derating in high-ambient designs. |
Compared with Vishay VS-MBR20100CT and ON Semi MBR20100CT, the MBR20100CT-Y offers lower VF (0.95V vs. 0.87V/0.89V), tighter IR spec (5mA vs. unspecified/10mA), and guaranteed halogen-free construction - making it preferred for high-efficiency, long-lifecycle industrial and telecom power systems.

FAQ
What is the maximum junction temperature rating for MBR20100CT-Y?
The MBR20100CT-Y has a maximum junction temperature (TJ max) of +150°C, allowing reliable operation in industrial environments with ambient temperatures up to 85°C when properly heatsinked. This rating is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet Version B2104, and applies across all variants in the MBR20xxCT-Y family including MBR20100CT-Y.
Does MBR20100CT-Y have a common-cathode configuration?
Yes, MBR20100CT-Y uses a dual-common-cathode configuration: Pins 1 and 3 are anodes for two independent Schottky diodes, and Pin 2 is their shared cathode terminal. This is explicitly defined in the package outline and pin diagram on page 6 of the TSC datasheet, and enables efficient dual-output or center-tapped transformer rectification without external interconnects.
What is the forward voltage specification for MBR20100CT-Y at full rated current?
At 20A and 25°C junction temperature, the forward voltage (VF) for MBR20100CT-Y is specified as ≤0.95V per diode. This value is listed in the Electrical Specifications table under "Forward voltage per diode" for the MBR20100CT-Y row, and reflects worst-case conduction loss under nominal conditions - critical for calculating thermal rise and system efficiency.
Is MBR20100CT-Y halogen-free and RoHS compliant?
Yes, MBR20100CT-Y is both RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the Features section of the official TSC datasheet. The "-Y" suffix denotes green compound packaging, and the device carries full compliance documentation traceable to TSC's manufacturing lot records and material declarations.
What is the thermal resistance from junction to case (RθJC) for MBR20100CT-Y?
The junction-to-case thermal resistance (RθJC) for MBR20100CT-Y is 2°C/W, as specified in the Thermal Performance table for the MBR2090CT-Y through MBR20200CT-Y group. This value is measured under standardized conditions and enables accurate heatsink sizing for applications where the TO-220AB tab is directly mounted to a thermal plane or extrusion.
