Product details
Overview
MBRS2050CT from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) 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 (0.80 V max at 10 A, 25°C) and is optimized for high-efficiency DC–DC converters and switching power supplies.
For engineers reviewing the MBRS2050CT datasheet, MBRS2050CT pinout, MBRS2050CT application, or MBRS2050CT equivalent, key selection criteria include its dual-common-cathode configuration, thermal resistance (RθJC = 1.5°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance - all critical for automated SMT assembly and industrial-grade thermal reliability.
Technical Context
The MBRS2050CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, enabling synchronous rectification or dual-output configurations. Its guard ring structure provides overvoltage protection, and it supports high dv/dt (10,000 V/μs) for fast-switching topologies.
Designed for operation across -55°C to +150°C junction range, the device maintains low leakage (≤10 mA at 125°C, rated VR) and stable forward voltage across load (0.95 V max at 20 A, 25°C) and temperature (0.85 V max at 20 A, 125°C), ensuring predictable conduction loss in thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum reverse blocking capability per diode; defines usable input voltage headroom in buck or flyback secondary-side rectification. |
| IF | 20 A - Continuous average forward current per diode; determines steady-state power handling without derating at TC ≤ 110°C. |
| IFSM | 150 A - Non-repetitive surge rating (8.3 ms half-sine); supports inrush and transient overload tolerance in SMPS startup. |
| VF @ 10 A, 25°C | 0.80 V max - Low conduction loss per diode; reduces heat generation and improves efficiency vs. standard PN rectifiers. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables direct heatsinking via PCB copper pour or external heatsink for high-power density designs. |
| IR @ 50 V, 125°C | 10 mA max - Reverse leakage per diode at elevated temperature; impacts standby power and thermal runaway risk in parallel configurations. |
Pinout & Package

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 = 1.0°C/W, higher surge rating (200 A). | Requires through-hole mounting and larger heatsink footprint; better suited for high-thermal-margin legacy designs. | Choose VS-20CPH05 only if board-level thermal design accommodates TO-247 and higher surge immunity is mandatory. |
| ON Semiconductor MBR2050CT | Identical electrical specs and TO-263AB package; same pinout and marking convention; minor differences in leakage (15 mA max at 125°C vs. 10 mA for MBRS2050CT). | No layout or firmware changes needed; fully interchangeable in new designs where tighter IR spec is not required. | MBRS2050CT offers lower high-temp leakage - prefer for thermally aggressive environments like enclosed telecom gear. |
Compared with VS-20CPH05 and MBR2050CT, the MBRS2050CT balances surface-mount compatibility, industry-leading thermal resistance (1.5°C/W), and superior high-temperature leakage performance - making it optimal for space-constrained, convection-cooled industrial and computing power stages.

FAQ
What is the maximum junction temperature rating for MBRS2050CT?
The MBRS2050CT has a maximum junction temperature (TJ) of +150°C, with operational range from -55°C to +150°C. This rating allows reliable use in thermally demanding applications such as enclosed server power supplies and industrial motor drives, provided the thermal design maintains junction temperature below this limit using the specified RθJC = 1.5°C/W path to the PCB or heatsink.
Does MBRS2050CT support automated SMT placement?
Yes, MBRS2050CT supports automated surface-mount placement. It is qualified to J-STD-020 Level 1 moisture sensitivity, requires no pre-bake, and features matte tin-plated leads compliant with J-STD-002 solderability standards. Its TO-263AB (D2PAK) footprint is widely supported by pick-and-place equipment and reflow profiles for lead-free assembly.
What is the forward voltage specification for MBRS2050CT at full rated current?
At 20 A and 25°C, the MBRS2050CT has a maximum forward voltage (VF) of 0.95 V per diode. At 20 A and 125°C, VF remains ≤ 0.85 V. These values are measured under pulsed conditions (PW = 0.3 ms) and reflect real-world conduction loss in high-frequency DC–DC converters operating near full load.
Is MBRS2050CT pin-compatible with other parts in the MBRS20xxCT family?
Yes, all MBRS20xxCT variants (e.g., MBRS2035CT, MBRS2060CT, MBRS20100CT) share identical TO-263AB (D2PAK) package dimensions, pinout (anode1–cathode–anode2), and mechanical footprint. Voltage rating differences (35 V to 150 V) do not affect physical compatibility, enabling design reuse across output voltage requirements without PCB revision.
What does the "CT" suffix indicate in MBRS2050CT?
The "CT" suffix in MBRS2050CT denotes a common-cathode dual-diode configuration - meaning the two internal Schottky dies share a single cathode terminal (pin 2), with independent anodes at pins 1 and 3. This configuration is essential for dual-output rectification, OR-ing, and synchronous rectifier topologies requiring matched diode characteristics in one package.
