Product details
Overview
MBRS2550CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 50 V repetitive peak reverse voltage, and 200 A non-repetitive surge current; it delivers low forward voltage (0.75 V max at 12.5 A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in compact SMPS designs.
For engineers reviewing the MBRS2550CT datasheet, MBRS2550CT pinout, MBRS2550CT application, or MBRS2550CT equivalent, key selection considerations include its 50 V VRRM, dual-common-cathode configuration, 1.0 °C/W junction-to-case thermal resistance, and suitability for high-current DC/DC output rectification where low conduction loss and fast switching are critical.
Technical Context
The MBRS2550CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, supporting synchronous or parallel rectification topologies. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
Designed for operation at junction temperatures from –55°C to +150°C, the device exhibits 10 mA max reverse leakage at 50 V and 125°C, and maintains stable forward voltage performance across temperature-0.65 V typ at 12.5 A and 125°C-enabling predictable thermal management in high-density power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum blocking voltage per diode; defines safe operating limit in DC/DC secondary-side rectification |
| IF | 25 A - Continuous average forward current per diode; supports high-output-current SMPS without forced air cooling |
| IFSM | 200 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overload events |
| VF @ 12.5A, 25°C | 0.75 V max - Low conduction loss reduces power dissipation and improves system efficiency |

FAQ
What is the maximum junction temperature rating for MBRS2550CT?
The MBRS2550CT has a maximum junction temperature (TJ) rating of +150°C, allowing reliable operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. This rating is supported by its 1.0 °C/W junction-to-case thermal resistance and TO-263AB package construction. The MBRS2550CT must be mounted on adequate PCB copper area to maintain this limit under full 25 A load.
Does MBRS2550CT have a common-cathode or common-anode configuration?
The MBRS2550CT uses a dual common-cathode configuration: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This arrangement enables simultaneous conduction of both diodes into a single output rail, ideal for interleaved or dual-output rectification. The MBRS2550CT marking diagram and mechanical drawings confirm this pinout, and it is consistent across the MBRS25xxCT family.
What is the forward voltage specification for MBRS2550CT at full rated current?
At 25 A average forward current and 25°C junction temperature, the MBRS2550CT has a maximum forward voltage (VF) of 0.90 V per diode. At 12.5 A and 25°C, VF is guaranteed ≤ 0.75 V. These values are measured under pulsed conditions per JEDEC standards and reflect real-world conduction losses used in thermal modeling for the MBRS2550CT.
Is MBRS2550CT suitable for use in RoHS-compliant and halogen-free designs?
Yes, the MBRS2550CT is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound and matte tin-plated terminals meet these environmental requirements without derating or performance compromise. This makes the MBRS2550CT appropriate for consumer, industrial, and telecom equipment subject to strict material declarations and sustainability mandates.
What packaging and reel quantity is available for MBRS2550CT?
The MBRS2550CT is supplied in TO-263AB (D2PAK) package on tape-and-reel format, with 800 units per reel. This packing method supports automated SMT placement and is compatible with standard pick-and-place equipment. The MBRS2550CT moisture sensitivity level is J-STD-020 Level 1, meaning no dry-pack or baking is required prior to assembly.
