Product details
Overview
MBRS2050CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20A average forward current, 50V repetitive peak reverse voltage, and 150A surge current, with 0.95V max forward voltage at 20A/25°C - used in high-efficiency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRS2050CT datasheet, MBRS2050CT pinout, MBRS2050CT application, or MBRS2050CT equivalent, key selection criteria include thermal resistance (1.5°C/W), low VF at high temperature, dual-diode configuration for center-tapped or parallel operation, and J-STD-020 Level 1 moisture sensitivity for standard reflow compatibility.
Technical Context
The MBRS2050CT integrates two independent Schottky diodes in a single TO-263AB thermally optimized package, sharing a common cathode configuration (center-tap anode layout not applicable; dual anode–common cathode). Its 50V VRRM rating targets mid-voltage switching applications where low conduction loss and fast recovery are critical.
Thermal performance is defined by RθJC = 1.5°C/W (typical), enabling sustained 20A operation with adequate heatsinking. Reverse leakage remains ≤10 mA at 125°C, supporting stable performance in elevated ambient environments typical of enclosed power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum non-repetitive reverse blocking voltage per diode; defines safe operating range in flyback or forward converter secondary circuits |
| IF | 20 A - continuous average forward current per diode at TC = 110°C; sets baseline conduction capability without derating |
| IFSM | 150 A - peak non-repetitive surge current (8.3 ms half-sine); supports cold-start and transient overload resilience |
| VF @ 20A, 25°C | 0.95 V max - low forward drop directly reduces conduction losses and improves system efficiency above 90% |
| RθJC | 1.5 °C/W - junction-to-case thermal resistance; enables direct thermal interface to PCB copper or heatsink for thermal management |
| TJ max | +150 °C - maximum junction temperature; allows operation in compact, high-power-density designs with limited airflow |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with exposed thermal pad. Cathode common to terminal 3; terminals 1 and 2 are anodes of the two independent Schottky dies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Independent input path for first rectification channel; electrically isolated from Diode 2 anode |
| 2 | Anode of Diode 2 | Independent input path for second rectification channel; enables dual-output or phase-split configurations |
| 3 | Common Cathode | Shared output node; must be connected to system ground or return rail; primary thermal conduction path via exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage (0.95 V max @ 20A) | Reduces I²R losses by >30% vs. comparable Si PN rectifiers, improving efficiency in 12–48 V output SMPS |
| Guard ring structure | Enhances ruggedness against voltage transients and edge breakdown, extending reliability in unregulated input stages |
| J-STD-020 Level 1 moisture sensitivity | Permits standard reflow soldering without baking; eliminates pre-conditioning delays in high-volume SMT lines |
| Dual-die integration in D2PAK | Provides space savings over two discrete TO-220 devices while maintaining identical thermal interface and mounting footprint |

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 50 V VRRM, 20 A IF, but TO-247AC package; RθJC = 1.8°C/W; VF = 0.82 V typ @ 20A | Requires larger PCB footprint and different mounting; better suited for forced-air-cooled systems | Select when higher surge margin or legacy TO-247 layout reuse is prioritized over space-constrained SMT assembly |
| ON Semiconductor MBR2050CT | Identical electrical specs and TO-263AB package; VF = 0.92 V max @ 20A/25°C; same 1.5°C/W RθJC | Drop-in compatible in footprint and thermal interface; minor VF improvement but same qualification level | Preferred for second-source assurance where Taiwan Semiconductor supply continuity is a concern |
Compared with VS-20CPH05 and MBR2050CT, the MBRS2050CT offers optimal balance of low-profile SMT integration, proven thermal performance, and cost-effective dual-die packaging - making it ideal for space-constrained, high-volume power supply designs where board area and reflow compatibility are critical.

FAQ
What is the pin configuration of the MBRS2050CT?
The MBRS2050CT uses a 3-pin TO-263AB (D2PAK) package with terminals 1 and 2 as independent anodes and terminal 3 as the common cathode. The exposed thermal pad is electrically connected to the cathode and must be soldered to a large copper pour for thermal and electrical integrity. This configuration supports dual-channel rectification or paralleled operation.
Does the MBRS2050CT support reflow soldering without baking?
Yes, the MBRS2050CT has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it can be subjected to standard lead-free reflow profiles without prior baking. This simplifies manufacturing flow and avoids yield loss from moisture-induced popcorning during assembly.
What is the maximum junction temperature rating for the MBRS2050CT?
The MBRS2050CT has a maximum junction temperature (TJ) of +150°C, allowing reliable operation in thermally demanding environments such as enclosed power supplies or industrial enclosures with limited airflow. Derating curves in the datasheet define usable current versus case temperature.
How does the forward voltage of the MBRS2050CT vary with temperature?
At 20A, the MBRS2050CT exhibits a forward voltage of 0.95 V max at 25°C and 0.85 V max at 125°C. This negative temperature coefficient improves thermal stability under load, reducing risk of thermal runaway compared to silicon PN rectifiers.
Is the MBRS2050CT RoHS and halogen-free compliant?
Yes, the MBRS2050CT is RoHS compliant and halogen-free per IEC 61249-2-21. Lead-free matte tin plating on terminals meets J-STD-002 solderability requirements, and the molding compound complies with UL 94V-0 flammability standards.
