Product details
Overview
MBRS2550CT from Taiwan Semiconductor is a 25A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 50V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C; it delivers low forward voltage (0.75V max at 12.5A/25°C) and is used in high-efficiency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRS2550CT datasheet, MBRS2550CT pinout, MBRS2550CT application, or MBRS2550CT equivalent, key selection criteria include its 50V VRRM rating, dual-common-cathode configuration, thermal resistance (RθJC = 1°C/W), moisture sensitivity level 1 compliance, and suitability for automated SMT placement in power supply designs.
Technical Context
This device integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, enabling synchronous or parallel rectification topologies. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
The MBRS2550CT operates across -55°C to +150°C junction temperature range, supports 8.3ms half-sine surge currents up to 200A, and exhibits low reverse leakage (≤200µA at 50V/25°C, ≤10mA at 50V/125°C), making it suitable for high-frequency switching applications where conduction loss and thermal management are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in DC-DC flyback or forward converter secondary circuits. |
| IF | 25 A - Continuous average forward current per diode; enables high-power density rectification without forced air cooling in compact adapters. |
| IFSM | 200 A - Non-repetitive peak surge current capability; withstands inrush and transient overload events in industrial power supplies. |
| VF (max) | 0.75 V @ 12.5A, 25°C - Low forward voltage drop reduces conduction losses and improves system efficiency above 90% in 12V–48V output SMPS. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct heatsinking via PCB copper pour or external heatsink for sustained 25A operation. |
| IR (max) | 200 µA @ 50V, 25°C - Low reverse leakage minimizes standby power loss and improves light-load efficiency in energy-sensitive applications. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with common cathode (pin 2), anode 1 (pin 1), and anode 2 (pin 3). Case meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky diode; connects to transformer secondary or input rail in dual-output or interleaved rectifier designs. |
| Pin 2 | Cathode (common) | Shared cathode node; serves as output reference point for both diodes and primary thermal path to PCB heatsink area. |
| Pin 3 | Anode 2 | Input terminal for second Schottky diode; enables dual-channel or redundancy configurations without discrete component duplication. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum junction temperature rating for MBRS2550CT?
The MBRS2550CT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version N2103. This allows sustained operation in high-ambient environments such as enclosed server PSUs or industrial motor drives without thermal shutdown, provided RθJC = 1°C/W and adequate PCB copper area is used for heat dissipation. The MBRS2550CT maintains specified electrical parameters up to this limit.
Is MBRS2550CT suitable for automated SMT assembly?
Yes, the MBRS2550CT is explicitly designed for automated placement and reflow soldering. It carries moisture sensitivity level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH without baking. Its TO-263AB (D2PAK) package features matte tin-plated leads compliant with J-STD-002, ensuring reliable wetting and joint formation during standard lead-free reflow profiles. This makes MBRS2550CT ideal for high-throughput manufacturing lines.
What is the reverse leakage current specification for MBRS2550CT at 125°C?
At 125°C junction temperature and rated 50V reverse voltage, the MBRS2550CT exhibits a maximum reverse leakage current (IR) of 10 mA per diode, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value is measured under pulse conditions (PW = 30 ms) and reflects real-world behavior in thermally stressed applications like automotive auxiliary supplies or industrial converters operating near thermal limits.
Does MBRS2550CT have a guard ring structure?
Yes, the MBRS2550CT incorporates an integrated guard ring for overvoltage protection, as confirmed in the FEATURES section of the official Taiwan Semiconductor datasheet. This structural feature enhances edge termination robustness, improving resistance to voltage transients and preventing premature avalanche breakdown during fast-rising reverse voltage events-critical in flyback and resonant converter topologies where di/dt and dv/dt stresses are high.
What is the forward voltage drop of MBRS2550CT at full rated current and room temperature?
The MBRS2550CT has a maximum forward voltage (VF) of 0.90 V at 25.0 A and 25°C, per the Electrical Specifications table. This value represents worst-case conduction loss under full DC load, enabling accurate thermal modeling and efficiency calculation. At half-rated current (12.5 A), VF is capped at 0.75 V, confirming strong scalability for partial-load operation in variable-power systems.
