Product details
Overview
MBRF1050CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 10 A average forward current, 50 V repetitive peak reverse voltage, and 120 A non-repetitive surge current; it delivers low forward voltage (0.80 V max at 10 A, 25°C) and operates up to 150°C junction temperature, used in high-efficiency DC/DC converters.
For engineers reviewing the MBRF1050CT datasheet, MBRF1050CT pinout, MBRF1050CT application, or MBRF1050CT equivalent, key selection considerations include its 50 V VRRM rating, dual-common-cathode configuration, thermal resistance of 3.5°C/W, AEC-Q101 qualification availability, and compatibility with high-frequency switching topologies requiring low conduction loss.
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its architecture enables synchronous rectification and center-tapped transformer secondary rectification without external parallel diodes.
The MBRF1050CT exhibits 100 µA maximum reverse leakage at 25°C and 10 mA at 125°C under rated 50 V reverse bias, with dv/dt capability of 10,000 V/µs and guard ring protection against transient overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines usable input voltage range in buck or flyback outputs. |
| IF(AV) | 10 A - Continuous average forward current per diode; supports sustained 12–24 V output stages delivering >100 W. |
| VF @ 10A, 25°C | 0.90 V max - Low conduction loss reduces heat generation and improves efficiency in high-current SMPS designs. |
| IFSM | 120 A - Peak non-repetitive surge current handling; withstands inrush and short-circuit transients in power adapters. |
| RθJC | 3.5 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting for thermal management without forced air. |
| TJ max | 150 °C - Maximum operating junction temperature; supports industrial ambient conditions up to 85°C with appropriate derating. |
| IR @ 50 V, 125°C | 10 mA - Reverse leakage level at elevated temperature; impacts standby power and thermal runaway risk in high-temp operation. |
Pinout & Package
Package: ITO-220AB - Thermally optimized through-hole package with insulated tab, UL 94V-0 molding compound, matte tin-plated leads, and 1.70 g mass; designed for mechanical mounting via screw (0.56 N·m max torque) and direct heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Lead 2 (Cathode) | Common Cathode | Shared cathode connection for both diodes; simplifies PCB layout in center-tapped or dual-output topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage by preventing edge breakdown; critical for unregulated line inputs. |
| AEC-Q101 qualification option | Available in H-suffix variant (MBRF1050CTH); meets automotive stress test requirements for under-hood applications. |
| Low thermal resistance | 3.5°C/W RθJC enables >8 W dissipation at ΔT = 28°C above heatsink - sufficient for 10 A continuous conduction mode. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive; supports environmentally regulated industrial and consumer product certifications. |

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-MBR1050CT | Identical 10 A / 50 V rating, same ITO-220AB package, VF = 0.85 V max at 10 A (25°C) - slightly higher conduction loss. | No AEC-Q101 qualified variant offered; not certified for automotive use. | Select when AEC-Q101 compliance is unnecessary and Vishay supply chain preference applies. |
| ON Semiconductor MBR1050CT | Same electrical specs and package; datasheet specifies 0.82 V VF max at 10 A (25°C), tighter tolerance than MBRF1050CT's 0.90 V. | Not listed as AEC-Q101 qualified in current documentation; lacks guard ring feature per published datasheet. | Prefer where lower VF tolerance is critical and guard ring protection is not required for the target transient environment. |
Compared with VS-MBR1050CT and MBR1050CT, the MBRF1050CT offers verified guard ring protection and optional AEC-Q101 qualification (MBRF1050CTH), making it uniquely suitable for automotive auxiliary supplies and industrial systems exposed to load dump or ESD transients.

FAQ
What is the maximum junction temperature rating for MBRF1050CT?
The MBRF1050CT has a maximum junction temperature (TJ max) of +150°C, allowing reliable operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood auxiliary modules. This rating is maintained across its full current and voltage operating range when thermal design respects the 3.5°C/W junction-to-case resistance and proper heatsinking is applied. The MBRF1050CT must be derated linearly above 25°C ambient per the forward current derating curve in the official TSC datasheet.
Does MBRF1050CT have AEC-Q101 qualification?
The base MBRF1050CT is not AEC-Q101 qualified, but the variant MBRF1050CTH - indicated by the "H" suffix in the ordering code - is fully AEC-Q101 qualified per Rev. M2105 documentation. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. Engineers specifying MBRF1050CT for automotive applications must order the H-suffix version to meet functional safety requirements.
What is the pin configuration and polarity marking for MBRF1050CT?
The MBRF1050CT uses a three-terminal ITO-220AB package with terminals: Tab (Anode 1), Lead 1 (Anode 2), and Lead 2 (Common Cathode). Polarity is marked on the device body with a cathode band adjacent to Lead 2. The tab is electrically active and insulated - it must be isolated from chassis ground unless using an insulating mounting kit. This configuration supports center-tapped transformer rectification and dual-output DC/DC designs without external diode paralleling.
How does the forward voltage of MBRF1050CT vary with temperature and current?
The MBRF1050CT forward voltage decreases with rising junction temperature: at 10 A, VF is 0.90 V max at 25°C but drops to 0.75 V max at 125°C. This negative temperature coefficient helps balance current sharing in parallel configurations. At lower currents (5 A), VF is 0.80 V max (25°C) and 0.65 V max (125°C). These values are measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects, as specified in the TSC datasheet.
What packaging and reel options are available for MBRF1050CT?
The MBRF1050CT is supplied in tube packaging: 50 units per tube. It is not offered in tape-and-reel format by Taiwan Semiconductor. For automated assembly, customers must use tube-to-reel conversion equipment or specify the MBRF1050CTH variant, which shares identical packaging. Tube orientation follows standard ITO-220AB lead-down configuration with cathode band facing outward; no alternate packing formats (e.g., bulk, ammo pack) are supported per TSC ordering information.
