Product details
Overview
MBRF2050CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, rated for 20A average forward current, 50V repetitive peak reverse voltage, and 150A surge current. It delivers low forward voltage (0.95V max at 20A, 25°C) and high thermal efficiency with 3.5°C/W junction-to-case resistance, enabling use in automotive-grade DC/DC converters.
For engineers reviewing the MBRF2050CTH datasheet, MBRF2050CTH pinout, MBRF2050CTH application, or MBRF2050CTH equivalent, key selection criteria include its AEC-Q101 qualification, 50V VRRM, dual-common-cathode configuration, TJ = –55°C to +150°C operating range, and UL recognition (E-326243).
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package with matte tin-plated leads. Its guard ring structure provides overvoltage protection, and it supports high dv/dt (10,000 V/µs) for fast-switching topologies.
Designed for high-efficiency power conversion, MBRF2050CTH operates across –55°C to +150°C junction temperature, maintains <100 µA reverse leakage at 25°C and 50V, and exhibits 0.85V typical forward voltage per diode at 10A/125°C - critical for thermal management in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum blocking voltage per diode; defines safe operating limit in 48V automotive rail designs |
| IF | 20 A - continuous average forward current per diode; enables compact 1kW-class converter output stages |
| IFSM | 150 A - non-repetitive surge rating (8.3ms half-sine); withstands cold-crank and load-dump transients |
| VF @ 20A, 25°C | ≤0.95 V - low conduction loss per diode; reduces heat generation vs. silicon rectifiers by ~40% |
| RθJC | 3.5 °C/W - thermal resistance from junction to case; allows direct heatsink mounting without thermal interface pads |
| TJ Range | –55°C to +150°C - extended temperature capability required for under-hood automotive placement |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with integral metal tab for mechanical mounting and thermal dissipation. Matte tin-plated leads meet J-STD-002 solderability; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Case) | Common Cathode | Electrically connected to both diode cathodes; serves as primary thermal path and must be electrically isolated from PCB ground unless circuit topology requires common-cathode reference |
| Lead 1 | Anode 1 | Input terminal for first Schottky diode; used in dual-phase or interleaved rectification |
| Lead 2 | Anode 2 | Input terminal for second Schottky diode; enables independent control or parallel operation with shared cathode |

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-20CPH05-M3 | Same ITO-220AB package, 50V VRRM, but rated 20A avg per diode and 0.82V VF @ 20A/25°C; no AEC-Q101 qualification | Targeted at industrial/commercial SMPS; lacks automotive stress-test validation | Select when AEC-Q101 is not required and lower VF is prioritized over qualification |
| ON Semiconductor MBR2050CT | Identical electrical specs and ITO-220AB package, but not AEC-Q101 qualified; RoHS-compliant, halogen-free | Used in consumer adapters and generic DC/DC converters where automotive reliability is not mandated | Choose for cost-sensitive non-automotive designs requiring same performance without qualification overhead |
Compared with MBRF2050CTH, VS-20CPH05-M3 offers marginally lower forward voltage but omits AEC-Q101 validation, while MBR2050CT matches all electrical parameters yet lacks automotive qualification - making MBRF2050CTH the only option when both 50V/20A performance and AEC-Q101 compliance are mandatory.

FAQ
What is the AEC-Q101 qualification status of MBRF2050CTH?
MBRF2050CTH is explicitly AEC-Q101 qualified per the manufacturer's documentation and ordering code suffix "H". This includes validation across temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge tests required for automotive under-hood applications. The qualification applies directly to the MBRF2050CTH part number, not just the family.
What does the "CT" suffix mean in MBRF2050CTH?
The "CT" suffix in MBRF2050CTH denotes a dual-diode common-cathode configuration in ITO-220AB package. It distinguishes this variant from single-diode (e.g., MBRF2050TH) or dual-anode versions. The "H" further confirms AEC-Q101 qualification, making MBRF2050CTH the fully qualified dual-cathode variant.
What is the maximum junction temperature for MBRF2050CTH?
The absolute maximum junction temperature for MBRF2050CTH is +150°C, with a specified operating range of –55°C to +150°C. This rating is validated under AEC-Q101 test conditions and supported by thermal data showing 3.5°C/W junction-to-case resistance for the 50V–200V variants (MBRF2080CT–MBRF20200CT), applicable to MBRF2050CTH per datasheet grouping.
How does the forward voltage of MBRF2050CTH compare at different temperatures?
At 20A and 25°C, MBRF2050CTH has a maximum forward voltage of 0.95V per diode. At 20A and 125°C, the maximum rises to 0.85V - demonstrating positive thermal coefficient behavior typical of Schottky diodes. This 0.10V reduction at elevated temperature improves thermal stability in high-ambient environments like engine compartments.
Is MBRF2050CTH compatible with lead-free reflow soldering processes?
Yes, MBRF2050CTH features matte tin-plated leads compliant with J-STD-002 for solderability and qualified for lead-free reflow profiles up to 260°C peak temperature. The ITO-220AB molding compound meets UL 94V-0 flammability rating, and the device passes JEDEC JESD201 Class 2 whisker testing - confirming suitability for modern RoHS-compliant manufacturing.
