Product details
Overview
MBRF1050H from Taiwan Semiconductor is a 10A, 50V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.80V max forward voltage at 10A/25°C, 150A surge current capability, and guard ring over-voltage protection-used in automotive-grade DC-DC converters and industrial SMPS front-end rectification.
For engineers reviewing the MBRF1050H datasheet, MBRF1050H pinout, MBRF1050H application, or MBRF1050H equivalent, key selection criteria include its AEC-Q101 qualification, 50V VRRM, 10A continuous forward current, thermal resistance of 3°C/W (junction-to-case), and compatibility with high-efficiency, low-loss power conversion designs requiring robust surge handling.
Technical Context
This single-die Schottky rectifier operates with zero recovery time and low forward conduction loss, enabling high-frequency switching efficiency in buck-derived topologies. Its guard ring structure enhances ruggedness against transient over-voltage events common in automotive load-dump conditions.
The device sustains 150A non-repetitive surge current (8.3ms half-sine) and exhibits 10mA max reverse leakage at 125°C, supporting reliable operation in thermally constrained environments where junction temperature reaches 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in 48V automotive and 36V industrial bus applications. |
| IF | 10 A - Continuous average forward current; supports sustained power delivery without derating below 75°C case temperature. |
| IFSM | 150 A - Peak surge current rating; withstands inrush and fault transients in DC-DC input stages without failure. |
| VF (max) | 0.80 V @ 10A, 25°C - Low conduction loss directly reduces power dissipation and improves system efficiency by ~0.8W vs. silicon diodes. |
| RθJC | 3 °C/W - Junction-to-case thermal resistance; enables effective heatsinking via mounting screw to chassis or heatsink. |
| TJ max | 150 °C - Maximum operating junction temperature; allows use in under-hood automotive modules and sealed industrial enclosures. |
| IR (max) | 10 µA @ 25°C, 10 mA @ 125°C - Reverse leakage behavior confirms stable blocking performance across full temperature range. |
Pinout & Package
Package: ITO-220AC - Insulated TO-220 variant with electrically isolated tab, matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to unregulated input rail; must be routed with low-inductance path for high di/dt stability. |
| Cathode (Lead 2) | Output current exit point | Feeds downstream filter capacitor or converter switch node; polarity marking on case ensures correct orientation. |
| Tab (Case) | Electrically isolated thermal path | Provides mechanical mounting and thermal conduction to heatsink; no electrical connection to internal die. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements including HTOL, TC, HAST, and ESD-enables use in engine control, ADAS, and body electronics. |
| Guard ring over-voltage protection | Prevents premature avalanche breakdown during line transients (e.g., ISO 7637-2 pulse 5a), improving reliability in 12V/24V vehicle systems. |
| Low forward voltage (0.80V max) | Reduces conduction loss by >40% vs. comparable fast recovery diodes, lowering thermal load in space-constrained power supplies. |
| 150A surge current rating | Supports cold-crank and jump-start scenarios without degradation-critical for battery-fed DC-DC converters in automotive applications. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally responsible manufacturing and end-of-life processing. |

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 | TO-220AB package (non-isolated tab); 0.75V VF typ @ 10A; not AEC-Q101 qualified. | Lacks automotive qualification; requires isolation sleeve if mounting to conductive heatsink. | Select when cost sensitivity outweighs automotive compliance and electrical isolation needs. |
| ON Semiconductor MBR1050CT | TO-220AB package; 0.78V VF max @ 10A; no guard ring; RoHS-compliant but not AEC-Q101 certified. | Suitable for commercial/industrial use only; lower surge immunity limits reliability in harsh automotive environments. | Choose for non-automotive 50V rectification where qualification and ruggedness are secondary to procurement availability. |
Compared with MBRF1050H, VS-MBR1050CT offers slightly lower forward voltage but lacks isolation and automotive qualification, while MBR1050CT trades ruggedness and qualification for broader commercial distribution-making MBRF1050H the sole choice for AEC-Q101–mandated, thermally demanding, and electrically isolated deployments.

FAQ
Is MBRF1050H AEC-Q101 qualified?
Yes, MBRF1050H is explicitly AEC-Q101 qualified per the ordering code suffix "H" and confirmed in the official Taiwan Semiconductor datasheet (Version M2105). This qualification covers stress tests including high-temperature operating life, temperature cycling, and electrostatic discharge-ensuring suitability for automotive electronic control units and ADAS subsystems. The MBRF1050H qualification status is documented in the product's mechanical and ordering information sections.
What is the maximum junction temperature for MBRF1050H?
The maximum junction temperature for MBRF1050H is 150°C, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating ambient range and supports continuous operation in thermally demanding environments such as under-hood automotive modules or sealed industrial power supplies. Derating curves confirm usable current capacity down to 0A at 150°C case temperature.
Does MBRF1050H have an electrically isolated tab?
Yes, MBRF1050H uses the ITO-220AC package, which features an electrically isolated metal tab. Unlike standard TO-220AB devices, the tab is insulated from the internal die and serves solely as a thermal conduction path to the heatsink. This eliminates the need for insulating washers or sleeves in grounded-chassis mounting configurations-reducing assembly complexity and improving thermal interface reliability.
What is the forward voltage of MBRF1050H at 10A and 125°C?
The forward voltage of MBRF1050H is 0.70V maximum at 10A and 125°C, per the Electrical Specifications table. This value reflects real-world conduction loss under elevated thermal stress and is critical for calculating worst-case power dissipation (PLOSS = IF × VF) in high-temperature applications like engine compartment power modules.
How does the guard ring in MBRF1050H improve reliability?
The guard ring in MBRF1050H mitigates edge breakdown under high dv/dt and transient over-voltage conditions-such as those defined in ISO 7637-2 Pulse 5a (load dump). By controlling electric field distribution at the die periphery, it prevents localized avalanche and premature failure, extending operational lifetime in automotive 12V/24V systems where voltage spikes exceed 60V routinely.
