Product details
Overview
MBRF2050CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 20 A average forward current, 50 V repetitive peak reverse voltage, and 150 A surge current. It delivers low forward voltage (0.95 V max at 20 A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in compact AC/DC adapters.
For engineers reviewing the MBRF2050CT datasheet, MBRF2050CT pinout, MBRF2050CT application, or MBRF2050CT equivalent, key selection criteria include its 50 V VRRM, dual-common-cathode configuration, thermal resistance of 3.5 °C/W (junction-to-case), and AEC-Q101 qualification availability - critical for automotive-grade SMPS and DC/DC converter designs requiring robust surge handling and low conduction loss.
Technical Context
The MBRF2050CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its 50 V VRRM and 150 A IFSM support high-reliability operation in switching power supplies where fast recovery and low forward drop reduce switching losses.
Thermal performance is defined by RθJC = 3.5 °C/W for the 50–200 V variants, and electrical behavior is characterized across temperature: VF = 0.85 V typ at 10 A / 125°C, IR = 10 mA max at 50 V / 125°C - confirming stable performance under elevated thermal stress in enclosed power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum reverse blocking capability without breakdown; sets upper limit for input voltage derating in 24–48 V DC/DC stages. |
| IF | 20 A - Continuous average forward current per diode; supports 100 W+ output in compact adapter designs with forced-air cooling. |
| IFSM | 150 A - Non-repetitive surge rating (8.3 ms half-sine); withstands inrush currents during cold-start of industrial SMPS. |
| VF | 0.95 V max @ 20 A, 25°C - Low conduction loss enables >92% efficiency in 12 V output buck converters at full load. |
| RθJC | 3.5 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting to maintain TJ < 135°C at 20 A in ambient ≤ 60°C. |
| TJ max | 150 °C - Maximum operating junction temperature; supports extended lifetime in sealed enclosures with limited airflow. |
Pinout & Package
Package: ITO-220AB - Thermally optimized 3-pin through-hole package with isolated metal tab (cathode-connected), matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first Schottky die | Connects to input-side switching node; requires PCB copper pour for thermal dissipation. |
| Pin 2 (Cathode) | Common cathode terminal | Electrically ties both diodes' cathodes; serves as main output return path and thermal interface to heatsink. |
| Pin 3 (Anode 2) | Anode of second Schottky die | Enables dual-output or interleaved topology; electrically isolated from Pin 1 except via shared cathode. |
Key Features
| Feature | Design Value |

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 | Same ITO-220AB package, 20 A / 50 V, but VF = 0.78 V typ @ 20 A / 125°C (lower than MBRF2050CT's 0.85 V). | Higher thermal efficiency in high-ambient telecom systems; lacks AEC-Q101 option. | Select when lowest possible conduction loss at elevated temperature is prioritized over automotive qualification. |
| ON Semiconductor MBR2050CT | Identical ratings (20 A / 50 V), same dual-common-cathode ITO-220AB package, but RθJC = 3.0 °C/W (slightly better thermal performance). | Preferred for space-constrained industrial converters needing marginally lower junction rise. | Choose when tighter thermal budget exists and manufacturer dual-sourcing is required. |
Compared with VS-20CPH05 and MBR2050CT, the MBRF2050CT offers AEC-Q101 qualification as standard option and guard ring protection - making it uniquely suitable for automotive auxiliary power supplies where overvoltage transients and long-term reliability are critical, despite slightly higher VF at high temperature.

FAQ
What is the maximum junction temperature rating for the MBRF2050CT?
The MBRF2050CT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows sustained operation in thermally demanding environments such as enclosed power adapters or automotive engine-bay auxiliary supplies, provided thermal design maintains actual TJ below this limit. Derating curves confirm usable current down to 125°C case temperature.
Is the MBRF2050CT pin-compatible with other parts in the MBRF20xxCT family?
Yes, all MBRF20xxCT variants - including MBRF2035CT, MBRF2050CT, and MBRF20200CT - share identical ITO-220AB package dimensions, pinout (Anode1–Cathode–Anode2), and mounting specifications. This enables voltage-scaling flexibility within the same PCB layout, though thermal and electrical performance varies per VRRM grade.
Does the MBRF2050CT have AEC-Q101 qualification?
The MBRF2050CT is available in an AEC-Q101 qualified version denoted by the suffix "H" (e.g., MBRF2050CTH). This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - confirming suitability for automotive power electronics where reliability under thermal and mechanical stress is mandatory.
What is the typical forward voltage of the MBRF2050CT at 20 A and 125°C?
The typical forward voltage (VF) of the MBRF2050CT is 0.85 V at 20 A and 125°C junction temperature, per electrical specifications table. This value reflects real-world conduction loss under elevated thermal conditions common in enclosed power supplies, supporting accurate efficiency modeling for thermal management validation.
How does the guard ring feature benefit the MBRF2050CT in switching applications?
The guard ring in the MBRF2050CT prevents premature edge breakdown during high dv/dt transients - specified at 10,000 V/µs - commonly encountered in high-frequency flyback or LLC resonant converters. This enhances long-term reliability by suppressing localized avalanche and leakage growth, especially under repeated voltage overshoot conditions in poorly damped layouts.
