Product details
Overview
MBRS2550CTH 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 supports automotive-grade reliability per AEC-Q101.
For engineers reviewing the MBRS2550CTH datasheet, MBRS2550CTH pinout, MBRS2550CTH application, or MBRS2550CTH equivalent, key selection criteria include junction-to-case thermal resistance (1°C/W), moisture sensitivity level (J-STD-020 Level 1), and dual-diode configuration for synchronous rectification or dual-channel freewheeling in DC/DC converters.
Technical Context
This device integrates two independent Schottky diodes in a single surface-mount D2PAK package, enabling dual-path operation without external paralleling. Its guard ring structure provides overvoltage protection, and the matte tin-plated terminals ensure reliable solderability per J-STD-002.
The MBRS2550CTH operates across –55°C to +150°C junction temperature range with 10,000 V/μs critical dv/dt rating, supporting high-frequency switching in automotive lighting and reverse battery protection circuits where fast recovery and low conduction loss are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in reverse-biased conditions. |
| IF(AV) | 25 A - Continuous average forward current per diode; determines steady-state power handling capability. |
| VF(max) | 0.75 V @ 12.5 A, 25°C - Low forward drop minimizes conduction losses in high-current DC/DC stages. |
| IFSM | 200 A - Peak non-repetitive surge current for 8.3 ms half-sine; enables robustness against load dump transients. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting for efficient thermal management. |
| IR(max) | 200 µA @ 50 V, 25°C - Low reverse leakage preserves efficiency in low-power standby modes. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with common cathode layout (Terminals: Anode1, Anode2, Cathode).
| Pin/Terminal | Circuit Role | Design Meaning |

Use Value: 10,000 V/μs dv/dt rating prevents false turn-on during fast voltage transitions across motor windings. |
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-25CPH05-M3 | Same TO-263AB package, 50 V VRRM, but single-diode (not dual); VF = 0.72 V @ 12.5 A. | Lacks dual-anode flexibility; requires two devices for dual-path use cases. | Select when only one rectification path is needed and board space permits discrete placement. |
| ON Semiconductor MBR2550CT | Identical electrical specs and TO-263AB package; differs in marking code and RoHS/halogen-free compliance status (MBR2550CT not halogen-free per IEC 61249-2-21). | Not AEC-Q101 qualified; unsuitable for automotive production without additional validation. | Choose MBRS2550CTH for automotive programs requiring full AEC-Q101 and halogen-free certification. |
Compared with VS-25CPH05-M3 and MBR2550CT, the MBRS2550CTH uniquely combines dual-diode topology, AEC-Q101 qualification, and halogen-free construction-enabling single-component solutions in space-constrained, automotive-grade DC/DC and protection designs.

FAQ
What is the maximum junction temperature rating for MBRS2550CTH?
The MBRS2550CTH has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating enables operation in under-hood automotive environments and high-temperature industrial enclosures. Thermal design must maintain TJ ≤ 150°C using the specified RθJC of 1°C/W and appropriate heatsinking. The MBRS2550CTH also supports storage down to –55°C, ensuring robustness across full automotive temperature ranges.
Is MBRS2550CTH pin-compatible with other parts in the MBRS25xxCTH family?
Yes, all MBRS25xxCTH variants-including MBRS2535CTH, MBRS2545CTH, MBRS2550CTH, MBRS2560CTH, MBRS2590CTH, MBRS25100CTH, and MBRS25150CTH-share identical TO-263AB (D2PAK) packaging and 3-pin pinout (Anode1, Anode2, Cathode). Voltage rating differences (35 V to 150 V) do not affect mechanical compatibility, allowing drop-in replacement during design iteration or voltage-scaling upgrades without PCB changes. The MBRS2550CTH maintains this uniformity.
Does MBRS2550CTH require special handling for moisture sensitivity?
No-MBRS2550CTH is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions (<30°C/60% RH) without baking prior to reflow. This eliminates pre-reflow bake cycles, reduces manufacturing risk, and supports just-in-time assembly. The MBRS2550CTH's Level 1 rating is confirmed in the mechanical data section of the official datasheet and applies across all temperature grades and production lots.
What is the forward voltage specification for MBRS2550CTH at elevated temperature?
At IF = 12.5 A and TJ = 125°C, the MBRS2550CTH exhibits a maximum forward voltage (VF) of 0.65 V, per electrical specifications table. This lower VF at high temperature reflects Schottky physics and improves system efficiency during thermal stress conditions. The MBRS2550CTH maintains this performance across its full operating range, with no derating required up to 150°C junction temperature.
Can MBRS2550CTH be used in reverse battery protection with 24 V systems?
Yes-MBRS2550CTH's 50 V VRRM rating provides sufficient margin above nominal 24 V system voltages, including worst-case transients such as load dump (ISO 7637-2 Pulse 5a, up to 35 V). In reverse battery protection, it operates as a series-connected forward-biased diode, blocking reverse current while adding only 0.75 V drop at 12.5 A. The MBRS2550CTH's AEC-Q101 qualification further validates its suitability for automotive 24 V applications.
