Product details
Overview
MBR2050CT from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-220AB package, rated for 50V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.80V typ. @ 10A, 25°C) and supports high-efficiency switching mode power supplies.
For engineers reviewing the MBR2050CT datasheet, MBR2050CT pinout, MBR2050CT application, or MBR2050CT equivalent, key selection criteria include its dual-diode configuration, thermal resistance (1°C/W), AEC-Q101 qualification eligibility, and validated performance at 125°C junction temperature.
Technical Context
The MBR2050CT integrates two independent Schottky diodes in a single TO-220AB case with common cathode configuration (indicated by "CT" suffix). Its guard ring structure provides overvoltage protection, and it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
Designed for high-frequency rectification, the device exhibits low reverse recovery charge (inherent to Schottky architecture), 10,000 V/μs critical dv/dt rating, and reverse leakage ≤10 mA @ 125°C - enabling stable operation in DC-DC converters and adapters under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or buck converter freewheeling paths. |
| IF(AV) | 20 A - Average forward current per diode; supports continuous conduction mode in 200–500W SMPS designs. |
| IFSM | 150 A - Non-repetitive surge current capability; withstands inrush and transient overload without failure. |
| VF @ 10A, 25°C | 0.80 V max - Low conduction loss improves system efficiency and reduces heatsink requirements. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance enables direct mounting to heatsinks for reliable 20A operation at TJ = 150°C. |
| IR @ 50V, 125°C | 10 mA max - Controlled reverse leakage ensures minimal standby power loss in high-temperature environments. |
Pinout & Package
Package: TO-220AB, 3-terminal plastic case with isolated tab (cathode-connected tab), matte tin-plated leads, 1.88g mass, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first Schottky diode; connects to switching node in center-tapped or dual-output topologies. |
| Pin 2 (Center) | Cathode (Common) | Shared cathode node for both diodes; electrically tied to metal tab; requires insulated mounting if referenced to non-ground potential. |
| Pin 3 (Right) | Anode 2 | Input terminal for second Schottky diode; enables dual-channel synchronous rectification or independent output paths. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events without external snubbers in SMPS secondary-side rectification. |
| AEC-Q101 qualification option | Available in H-suffix variant (MBR2050CTH); validated for automotive under-hood power conversion applications. |
| Low thermal resistance | 1°C/W RθJC allows 20A operation with modest heatsinking - critical for compact adapter and industrial PSU designs. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21; supports environmentally regulated industrial and consumer electronics manufacturing. |

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 50V VRRM, 20A IF, TO-220AC package (non-isolated tab); RθJC = 1.5°C/W; VF = 0.78V @ 10A. | Requires insulating washer for tab isolation; slightly higher thermal resistance limits sustained 20A operation in confined spaces. | Select when cost sensitivity outweighs thermal margin needs and tab isolation is not required. |
| ON Semiconductor MBR2050CTG | Identical electrical specs and TO-220AB package; Pb-free, halogen-free, and AEC-Q101 qualified (G suffix); same 1°C/W RθJC. | Drop-in replacement with identical pinout and thermal behavior; certified for automotive use without redesign. | Preferred for new automotive designs requiring full compliance documentation and traceable qualification. |
Compared with VS-20CPH05 and MBR2050CTG, the MBR2050CT offers superior thermal performance (1°C/W vs. 1.5°C/W) and tab isolation in TO-220AB, while MBR2050CTG provides identical performance with formal AEC-Q101 certification - making it ideal for safety-critical automotive auxiliary supplies.

FAQ
What is the pin configuration of the MBR2050CT?
The MBR2050CT uses a 3-pin TO-220AB package with common-cathode configuration: Pin 1 is Anode 1, Pin 2 (center) is the shared Cathode connected to the metal tab, and Pin 3 is Anode 2. The tab is electrically active and must be insulated if mounted to a grounded heatsink.
Is the MBR2050CT AEC-Q101 qualified?
The base MBR2050CT is not AEC-Q101 qualified; however, the MBR2050CTH variant is explicitly qualified per AEC-Q101. This distinction is defined in the ordering code - "H" suffix denotes automotive qualification, including stress testing for temperature cycling, humidity, and mechanical shock.
What is the maximum junction temperature rating for the MBR2050CT?
The MBR2050CT has a maximum junction temperature (TJ MAX) of +150°C, verified across its full operating range. This rating enables reliable operation in high-ambient environments such as enclosed power supplies and industrial control cabinets when paired with appropriate heatsinking.
How does the forward voltage of the MBR2050CT vary with temperature?
The MBR2050CT exhibits a negative temperature coefficient for forward voltage: VF drops from 0.80V typ. @ 10A, 25°C to 0.70V typ. @ 10A, 125°C. This behavior reduces conduction loss at elevated temperatures, improving thermal stability in sustained high-load conditions.
Can the MBR2050CT replace the MBR2045CT in an existing design?
Yes, the MBR2050CT can directly replace the MBR2045CT because both share identical package (TO-220AB), pinout, thermal resistance (1°C/W), and current ratings (20A IF, 150A IFSM); the only difference is VRRM increased from 45V to 50V - providing additional margin without circuit modification.
