Product details
Overview
MBRF2050HC0G from Taiwan Semiconductor is a 20A, 50V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.82V max forward voltage at 20A/25°C, 150A surge capability, and guard ring over-voltage protection for automotive-grade power conversion.
For engineers reviewing the MBRF2050HC0G datasheet, MBRF2050HC0G pinout, MBRF2050HC0G application, or MBRF2050HC0G equivalent, key selection factors include its 50V VRRM rating, 10mA reverse leakage at 125°C, UL Recognized File #E-326243 compliance, RoHS/halogen-free status, and suitability for high-efficiency DC-DC converters requiring low conduction loss.
Technical Context
This single-die Schottky rectifier uses platinum-silicide metallization to achieve low VF and fast switching with no minority-carrier storage delay. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.
The device operates across -55°C to +150°C junction temperature range with 3°C/W junction-to-case thermal resistance, enabling direct heatsink mounting without isolation washers in space-constrained SMPS designs.

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-20BQ050P-M3/45 | Same 50V VRRM, 20A IF, but TO-220AC package with non-isolated tab; 0.78V VF typical at 20A/25°C | Lacks AEC-Q101 qualification and UL recognition; not suitable for automotive safety-critical systems | Select when cost sensitivity outweighs automotive qualification needs and tab isolation is not required |
| ON Semiconductor MBR2050CT | Dual common-cathode configuration in TO-220AB; 0.85V VF max at 20A/25°C; no AEC-Q101 or UL listing | Provides dual-diode functionality for center-tapped transformer designs; unsuitable for single-diode ITO-220AC footprint | Choose only if dual-diode topology is needed and footprint compatibility is verified via mechanical drawing review |
Compared with VS-20BQ050P-M3/45 and MBR2050CT, the MBRF2050HC0G uniquely combines AEC-Q101 qualification, UL recognition, electrically isolated tab, and halogen-free construction-making it the only option qualified for automotive under-hood power conversion where regulatory compliance and thermal isolation are mandatory.

FAQ
What does the 'H' suffix in MBRF2050HC0G indicate?
The 'H' in MBRF2050HC0G denotes AEC-Q101 qualification, confirming that the MBRF2050HC0G has passed rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-for use in automotive electronic systems. This distinguishes it from non-H variants like MBRF2050C0G, which lack automotive qualification.
Is the tab of MBRF2050HC0G electrically isolated?
Yes, the tab of MBRF2050HC0G is electrically isolated from both anode and cathode terminals, as confirmed by the ITO-220AC package designation. This isolation allows direct mounting to grounded heatsinks without additional insulating hardware, simplifying thermal design in compact power supplies.
What is the maximum junction temperature rating for MBRF2050HC0G?
The MBRF2050HC0G has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from -55°C to +150°C. This rating supports reliable operation in under-hood automotive environments and high-ambient industrial enclosures when paired with appropriate heatsinking.
Does MBRF2050HC0G meet RoHS and halogen-free requirements?
Yes, MBRF2050HC0G is RoHS compliant and halogen-free per IEC 61249-2-21. The "C0G" suffix explicitly indicates green compound and halogen-free construction, ensuring environmental compliance for global electronics manufacturing and end-of-life disposal.
How does the forward voltage of MBRF2050HC0G compare at elevated temperature?
At 20A and 125°C, the MBRF2050HC0G exhibits a maximum forward voltage of 0.72V-lower than its 25°C rating of 0.82V-due to the negative temperature coefficient of Schottky diodes. This behavior improves thermal stability in high-power, high-temperature applications.
