Product details
Overview
MBRF10100CT-Y from Taiwan Semiconductor is a 10A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 100V repetitive peak reverse voltage (VRRM), 0.95V max forward voltage at 10A/25°C, and 120A surge current capability - used in high-efficiency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRF10100CT-Y datasheet, MBRF10100CT-Y pinout, MBRF10100CT-Y application, or MBRF10100CT-Y equivalent, key selection criteria include VRRM=100V, IF=10A per diode, dual common-cathode configuration, thermal resistance RθJC=3.5°C/W, and RoHS/halogen-free compliance for industrial power supply design.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 10A diodes sharing one cathode terminal, enabling synchronous or interleaved rectification topologies. Its guard ring structure provides overvoltage protection, and the ITO-220AB package supports direct heatsink mounting with 0.56 N·m maximum torque.
Designed for operation up to 150°C junction temperature, it delivers low conduction loss (VF ≤ 0.95V @ 10A/25°C) and fast switching (dv/dt = 10,000 V/μs), making it suitable for high-frequency switching applications where reverse recovery time is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage each diode withstands without breakdown |
| IF (per diode) | 10 A continuous - Rated average forward current per die at case temperature ≤ 100°C |
| IFSM | 120 A - Peak non-repetitive surge current (8.3 ms half-sine) the device handles without failure |
| VF @ 10A, 25°C | ≤ 0.95 V - Forward voltage drop per diode, directly determining conduction loss in power stage |
| RθJC | 3.5 °C/W - Thermal resistance from junction to case, defining heatsink sizing requirement |
| TJ max | +150 °C - Maximum allowable junction temperature, limiting safe operating area under load |
| IR @ 100V, 125°C | ≤ 5 mA - Reverse leakage per diode at rated voltage and elevated temperature, affecting standby loss |

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 | VRRM=100V, IF=10A, VF=0.92V @10A/25°C, RθJC=3.0°C/W, TO-220AC package (non-isolated tab) | Non-isolated tab requires insulating hardware for heatsink mounting; slightly lower thermal resistance | Select when mechanical isolation is handled externally and lower RθJC is prioritized over creepage/clearance |
| ON Semiconductor MBR10100CT | VRRM=100V, IF=10A, VF=0.95V @10A/25°C, RθJC=4.0°C/W, TO-220AC package | Higher thermal resistance requires larger heatsink; same electrical specs but different qualification grade | Choose for cost-sensitive industrial designs where extended qualification is not required |
Compared with MBRF10100CT-Y, VS-MBR10100CT offers better thermal performance but lacks internal insulation, while MBR10100CT trades thermal margin for broader commercial availability - all three support identical 100V/10A rectification roles in SMPS and adapters.

FAQ
What is the pin configuration of MBRF10100CT-Y?
The MBRF10100CT-Y uses a 3-pin ITO-220AB package with Pin 1 = Anode A, Pin 2 = Common Cathode, and Pin 3 = Anode B. This dual-anode, single-cathode layout supports full-wave or dual-output rectification without external interconnects. The metal tab is electrically isolated and thermally conductive, enabling direct heatsink mounting.
Does MBRF10100CT-Y support surface-mount assembly?
No, MBRF10100CT-Y is through-hole only, packaged in ITO-220AB with leads designed for axial insertion and wave soldering. It does not have gull-wing or J-lead terminations. Reflow profiles are not specified, and the device is not qualified for SMT processes per J-STD-020.
What is the maximum junction temperature rating for MBRF10100CT-Y?
The MBRF10100CT-Y has a maximum junction temperature (TJ) of +150°C, validated across its full operating range. This allows reliable operation in industrial environments up to +85°C ambient when properly heatsinked, with derating applied above 100°C case temperature per the forward current derating curve.
How does the guard ring feature benefit MBRF10100CT-Y in real-world use?
The guard ring in MBRF10100CT-Y enhances edge termination robustness, suppressing premature avalanche breakdown during voltage transients. In practice, this improves reliability in SMPS inputs exposed to line surges or inductive kickback, reducing field failure rates without requiring additional TVS clamping components.
Is MBRF10100CT-Y halogen-free and RoHS compliant?
Yes, MBRF10100CT-Y is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the matte tin-plated leads meet J-STD-002 solderability requirements - verified in TSC's B2105 revision documentation.
