Product details
Overview
MBRF15100CT-Y from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 15 A average forward current, 100 V repetitive peak reverse voltage, and 150 A surge current, with typical forward voltage of 0.92 V at 7.5 A and 25°C - used in high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the MBRF15100CT-Y datasheet, MBRF15100CT-Y pinout, MBRF15100CT-Y application, or MBRF15100CT-Y equivalent, key selection criteria include junction-to-case thermal resistance (3.5°C/W), low IR (≤100 µA at 25°C), RoHS/halogen-free compliance, and ITO-220AB mounting compatibility with 0.56 N·m torque limit.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 100 V/15 A dies in a single ITO-220AB thermally optimized package, enabling synchronous half-bridge or dual-output configurations without external paralleling. Its guard ring structure provides overvoltage protection, and dv/dt rating of 10,000 V/µs supports fast-switching topologies.
Designed for operation up to 150°C junction temperature, it delivers stable performance under high ambient conditions with thermal resistance RθJC = 3.5°C/W and reverse leakage ≤5 mA at 125°C - critical for compact, convection-cooled power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage per diode; defines safe operating range in flyback or boost output stages |
| IF | 15 A - continuous average forward current per diode; enables compact 30 W–100 W converter designs without forced air cooling |
| IFSM | 150 A - 8.3 ms half-sine surge rating; withstands inrush and transient overload in AC-DC front-ends |
| VF @ 7.5A, 25°C | 0.92 V - low conduction loss per diode; reduces power dissipation by ~14% vs. comparable 100 V Si diodes |
| RθJC | 3.5 °C/W - junction-to-case thermal resistance; allows direct heatsink mounting with predictable thermal margin |
| IR @ 100 V, 25°C | ≤100 µA - low reverse leakage per diode; minimizes standby power loss in energy-efficient adapters |

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-15CTH10-M3/45 | Same ITO-220AB package, 15 A/100 V rating, but higher VF (0.95 V typ. @ 7.5 A) and higher IR (200 µA @ 25°C) | Suitable for cost-sensitive consumer adapters where leakage <100 µA is not required | Prefer MBRF15100CT-Y when low standby loss or high-temperature stability is critical |
| ON Semiconductor MBR15100CT | Identical electrical specs but lacks halogen-free certification and JESD 201 whisker testing | Acceptable for non-regulated industrial use where RoHS+halogen compliance is not mandated | Select MBRF15100CT-Y for medical, telecom, or export-bound designs requiring full environmental compliance |
Compared with VS-15CTH10-M3/45 and MBR15100CT, the MBRF15100CT-Y offers lower reverse leakage and certified halogen-free construction - making it preferable for energy-efficient, regulated, and thermally constrained applications where long-term reliability and compliance are design-critical.

FAQ
What is the maximum junction temperature rating for the MBRF15100CT-Y?
The MBRF15100CT-Y has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in sealed or convection-cooled enclosures where case temperatures may reach 100–115°C. Derating curves confirm usable current capacity down to 7.5 A at 125°C case temperature, ensuring design margin across industrial temperature ranges.
Does the MBRF15100CT-Y have a common-cathode or common-anode configuration?
The MBRF15100CT-Y uses a dual-common-cathode configuration: both internal Schottky dies share a single cathode terminal (Lead 2), while Anode 1 is connected to the metal tab and Anode 2 to Lead 1. This arrangement is confirmed in the marking diagram and mechanical outline. It supports dual-output rectification and simplifies PCB routing in center-tapped transformer designs.
What is the forward voltage specification for MBRF15100CT-Y at full rated current?
The MBRF15100CT-Y does not specify forward voltage at 15 A in the published datasheet - only at 7.5 A (0.92 V typ. @ 25°C). At 15 A and 25°C, VF is unspecified; however, curve data shows typical VF ≈ 1.05–1.10 V. For thermal design, engineers should use the 7.5 A point with derating or consult the Fig.4 Typical Forward Characteristics graph for accurate modeling.
Is the MBRF15100CT-Y pin-compatible with other parts in the MBRF15xxCT-Y family?
Yes - all MBRF15xxCT-Y variants (45 V to 200 V) share identical ITO-220AB package dimensions, pinout, and thermal pad layout. The only differences are VRRM, VF, and IR; therefore, MBRF15100CT-Y can be substituted for MBRF1560CT-Y or MBRF1545CT-Y on the same footprint, provided voltage and leakage requirements are met.
What mounting torque is recommended for the MBRF15100CT-Y heatsink screw?
The recommended maximum mounting torque for the MBRF15100CT-Y is 0.56 N·m, as specified in the Mechanical Data section of the Taiwan Semiconductor datasheet. Exceeding this value risks cracking the ITO-220AB plastic body or deforming the internal lead frame, potentially compromising thermal performance and long-term reliability. Use a calibrated torque screwdriver and insulating washer when mounting to grounded heatsinks.
