Product details
Overview
MBRS20100CT from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 100V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and 150°C maximum junction temperature. It delivers low forward voltage (0.85 V max at 10 A, 25°C) and low reverse leakage (5 mA max at 100 V, 125°C), enabling high-efficiency operation in DC–DC converters and switching power supplies.
For engineers reviewing the MBRS20100CT datasheet, MBRS20100CT pinout, MBRS20100CT application, or MBRS20100CT equivalent, key selection criteria include its dual-common-cathode configuration, thermal resistance (RθJC = 2°C/W), moisture sensitivity level (MSL 1), and compatibility with automated SMT placement in high-current, medium-voltage rectification stages.
Technical Context
The MBRS20100CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection. Its design targets high-frequency switching applications where low forward voltage drop and fast recovery (no reverse recovery charge) reduce conduction and switching losses.
It operates across –55°C to +150°C junction temperature range, supports 8.3 ms half-sine surge currents up to 150 A, and features guard ring structure for enhanced overvoltage ruggedness. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode; defines upper limit of DC bus or output voltage it can safely clamp. |
| IF(AV) | 20 A - Average forward current per diode; determines continuous power-handling capability in thermally managed layouts. |
| IFSM | 150 A - Non-repetitive surge current rating; enables robust startup and fault tolerance in SMPS output stages. |
| VF @ 10A, 25°C | 0.85 V max - Low conduction loss per diode; directly reduces power dissipation and improves system efficiency. |
| RθJC | 2°C/W - Junction-to-case thermal resistance; allows accurate heatsink sizing when mounted on copper pads or external thermal planes. |
| IR @ 100V, 125°C | 5 mA max - Reverse leakage under worst-case thermal and voltage stress; impacts standby power and thermal runaway risk. |
| MSL Level | Level 1 - No floor life limitation before reflow; eliminates baking requirement and simplifies SMT line handling. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal, common-cathode dual-diode configuration. Case material meets UL 94V-0; terminals are matte tin-plated for reliable solder wetting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of Diode A | Connects to input/high-side node in dual-output or parallel rectifier topologies. |
| Pin 2 (Cathode) | Common Cathode | Shared output node; must be routed with low-inductance, high-current copper for both diodes. |
| Pin 3 (Anode B) | Anode of Diode B | Enables independent anode routing for center-tapped transformer or interleaved converter designs. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Improves avalanche ruggedness and prevents premature edge breakdown under transient overvoltage conditions. |
| Dual-die common-cathode layout | Reduces PCB footprint vs. two discrete SMD Schottkys; maintains symmetry for balanced current sharing in dual-phase outputs. |
| Low VF at high temperature | 0.85 V max at 10 A, 125°C - Ensures stable conduction loss across full operating range without thermal runaway. |
| J-STD-020 MSL Level 1 | Eliminates pre-reflow baking and moisture-related popcorning during reflow, lowering manufacturing cost and yield risk. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS directives - required for export to regulated markets and green electronics programs. |
Applications
| Server VRM Output Stage | Industrial DC–DC Converter |
|---|---|
Use Scenario: High-current, multiphase buck converter supplying CPU core voltage in datacenter servers. IC Role / Device Role / Timing Role: Output synchronous rectifier (replacing MOSFETs in some designs) or freewheeling diode in non-synchronous topology. Use Value: 20 A average current per diode and 2°C/W RθJC enable compact thermal design with minimal heatsinking on 2-oz copper. | Use Scenario: 48 V to 12 V isolated DC–DC module for factory automation controllers. IC Role / Device Role / Timing Role: Secondary-side rectifier in forward or flyback topology, handling 20 A continuous load. Use Value: 100 V VRRM provides 2× safety margin over 48 V nominal input; low VF minimizes heat generation in sealed enclosures. |
| Laptop Adapter Secondary Rectifier | Telecom Power Shelf Rectification |

IC Role / Device Role / Timing Role: Dual-anode rectifier feeding parallel output rails (e.g., +19 V and +5 V) from center-tapped transformer. Use Value: Common-cathode configuration reduces component count vs. two discrete diodes; TO-263AB fits tight board spacing while supporting automated placement. | Use Scenario: N+1 redundant 48 V output rectification in telecom power shelves. IC Role / Device Role / Timing Role: Primary secondary-side rectifier in each redundant module, operating continuously at elevated ambient temperatures. Use Value: 150°C TJ max and 5 mA IR at 125°C ensure reliability in forced-air-cooled, high-ambient environments typical of central offices. |
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-20CPH01 | Same TO-263AB package, 20 A/100 V, but VF = 0.87 V max @ 10 A, 25°C; RθJC = 2.2°C/W. | Slightly higher conduction loss and thermal resistance; suitable where minor efficiency trade-off is acceptable. | Preferred when cross-qualifying with Vishay-sourced BOMs or requiring alternate supply chain. |
| ON Semiconductor MBR20100CT | Identical electrical specs and TO-263AB mechanical outline; same marking format and MSL 1 rating. | No functional or layout impact; validated for direct substitution in existing designs. | Recommended for second-source assurance without redesign or qualification overhead. |
Compared with VS-20CPH01, MBRS20100CT offers lower VF and better thermal performance; versus MBR20100CT, it shares identical ratings and footprint but differs in manufacturer-specific process and qualification history-both support drop-in replacement in most industrial and computing applications.

FAQ
What is the maximum junction temperature rating for MBRS20100CT?
The MBRS20100CT has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in high-ambient environments such as enclosed power supplies and industrial control cabinets. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature, and thermal design must account for RθJC = 2°C/W to maintain safe junction limits under full load.
Does MBRS20100CT support automated SMT placement?
Yes, MBRS20100CT is explicitly designed for automated placement, as confirmed in its official features list. Its TO-263AB (D2PAK) package uses matte tin-plated leads compliant with J-STD-002 solderability standards, and its MSL Level 1 rating eliminates moisture sensitivity concerns during reflow. The symmetric 3-pin outline and standardized tape-and-reel packaging (800 units per reel) ensure compatibility with high-speed pick-and-place equipment.
What is the forward voltage specification for MBRS20100CT at full rated current?
At 20 A forward current and 25°C junction temperature, the MBRS20100CT exhibits a maximum forward voltage (VF) of 0.95 V per diode, as specified in the Electrical Specifications table. At elevated temperature (125°C), VF remains controlled at ≤0.85 V under the same 20 A condition-critical for maintaining efficiency and thermal stability in high-power density designs.
Is MBRS20100CT halogen-free and RoHS compliant?
Yes, MBRS20100CT is both halogen-free per IEC 61249-2-21 and RoHS compliant, as stated in the official Taiwan Semiconductor documentation. These compliance certifications are verified through material declarations and third-party testing, making MBRS20100CT suitable for export to EU, China, and other regulated markets requiring strict environmental substance controls.
What does the "CT" suffix indicate in MBRS20100CT?
The "CT" suffix in MBRS20100CT denotes a common-cathode dual-diode configuration in TO-263AB (D2PAK) package. This distinguishes it from single-diode variants (e.g., MBRS20100CT vs. MBRS10100T) and confirms internal connection of both cathodes to Pin 2. The marking code "MBRS20100CT" appears directly on the device body per the official marking diagram.
