Product details
Overview
MBR2550CTH from Taiwan Semiconductor is a 25A, 50V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.75V typical forward voltage at 12.5A/25°C and 10mA reverse leakage at 125°C, used in high-efficiency DC-DC converters and automotive-grade power supplies.
For engineers reviewing the MBR2550CTH datasheet, MBR2550CTH pinout, MBR2550CTH application, or MBR2550CTH equivalent, key selection criteria include its AEC-Q101 qualification, 200A surge rating, 1°C/W junction-to-case thermal resistance, and dual-diode configuration for center-tapped or full-wave rectification.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB thermally optimized package, enabling synchronous rectification or dual-output SMPS topologies. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.
The MBR2550CTH operates across -55°C to +150°C junction temperature range with 10,000 V/μs critical dv/dt rating, supporting fast-switching applications where low forward voltage drop and minimal reverse recovery charge are essential for efficiency.
Key Specifications

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 | Same 50V VRRM, 25A IF, but TO-247 package; 0.72V VF @ 12.5A/25°C; no AEC-Q101 qualification | Higher thermal performance (0.8°C/W) but lacks automotive qualification; requires PCB layout change | Select when higher thermal margin is needed and automotive compliance is not required |
| ON Semiconductor MBR2550CT | Identical electrical specs and TO-220AB package, but non-AEC-Q101 version; same marking except absence of "H" suffix | Not qualified for automotive use; suitable for industrial/commercial power supplies only | Select when cost sensitivity outweighs automotive reliability requirements |
Compared with VS-25CPH05 and MBR2550CT, the MBR2550CTH uniquely combines AEC-Q101 qualification, TO-220AB form factor, and validated 125°C reverse leakage-making it the only drop-in solution for automotive front-end power conversion where qualification and footprint are mandatory.

FAQ
What does the "H" suffix in MBR2550CTH signify?
The "H" suffix in MBR2550CTH indicates full AEC-Q101 qualification, confirming that the device has passed stress tests for automotive-grade reliability-including temperature cycling, humidity bias, and mechanical shock. This certification is documented in Taiwan Semiconductor's official qualification report K2104 and applies specifically to the MBR2550CTH, not the base MBR2550CT variant.
Is MBR2550CTH pin-compatible with MBR2550CT?
Yes, MBR2550CTH is mechanically and electrically pin-compatible with MBR2550CT-both use identical TO-220AB packaging, pinout, and thermal pad configuration. The only difference is AEC-Q101 qualification; no PCB or schematic changes are required when upgrading from MBR2550CT to MBR2550CTH in automotive designs.
What is the maximum operating junction temperature for MBR2550CTH?
The MBR2550CTH has a maximum rated junction temperature of +150°C, verified per JESD22-A108. Operation at this limit requires thermal design ensuring case temperature remains ≤100°C under full 25A load, leveraging its 1°C/W RθJC and proper heatsinking-critical for under-hood automotive applications.
Does MBR2550CTH support full-wave rectification?
Yes, MBR2550CTH supports full-wave rectification via its dual-anode/single-cathode configuration: Pins 1 and 3 serve as independent anodes, while Pin 2 (and the metal tab) forms the common cathode. This allows direct implementation in center-tapped transformer or dual-switch topologies without external diode pairing.
How does the guard ring in MBR2550CTH improve system reliability?
The guard ring in MBR2550CTH enhances edge termination robustness, suppressing surface leakage and preventing premature avalanche breakdown during voltage transients like ISO 7637-2 Pulse 5a (load dump). This feature directly improves field failure rates in 12V automotive systems where MBR2550CTH is deployed in alternator rectification and DC-DC pre-regulators.
