Taiwan Semiconductor Corporation MBRS2560CTH

Overview

MBRS2560CTH from Taiwan Semiconductor is a dual-die surface-mount Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 60 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 MBRS2560CTH datasheet, MBRS2560CTH pinout, MBRS2560CTH application, or MBRS2560CTH equivalent, key selection criteria include junction-to-case thermal resistance (1°C/W), reverse leakage (≤200 µA at 25°C), high dv/dt capability (10,000 V/µs), and suitability for DC/DC converters requiring low-loss freewheeling or reverse battery protection.

Technical Context

This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-263AB thermally optimized package, enabling shared heatsinking and compact layout in high-current power stages. Its guard ring structure enhances overvoltage ruggedness while maintaining low VF and fast switching without reverse recovery charge.

Designed for operation up to 150°C junction temperature, MBRS2560CTH sustains 25 A continuous conduction with 1°C/W junction-to-case thermal resistance, and exhibits stable reverse leakage (<10 mA at 125°C, 60 V) - critical for automotive lighting and 12 V/24 V system protection where thermal margin and leakage-induced standby loss must be minimized.

FAQ

What is the maximum junction temperature rating for MBRS2560CTH?

The MBRS2560CTH has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-density industrial power supplies. The device maintains specified electrical parameters up to this limit when thermal design respects the 1°C/W junction-to-case resistance. MBRS2560CTH must be mounted on adequate copper area to sustain continuous 25 A conduction without exceeding TJ MAX.

Is MBRS2560CTH pin-compatible with other parts in the MBRS25xCTH series?

Yes, all MBRS25xCTH variants - including MBRS2535CTH, MBRS2545CTH, MBRS2550CTH, MBRS2560CTH, MBRS2590CTH, MBRS25100CTH, and MBRS25150CTH - share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal assignment. MBRS2560CTH can be substituted within the same footprint for designs requiring 60 V blocking, while higher-voltage versions (e.g., MBRS25100CTH) retain mechanical compatibility but require verification of VF and leakage trade-offs.

Does MBRS2560CTH support automated SMT placement?

Yes, MBRS2560CTH is explicitly designed for automated placement per its mechanical data sheet: matte tin-plated leads meet J-STD-002 solderability requirements, moisture sensitivity level is rated at Level 1 (no baking required), and the TO-263AB body geometry is compatible with standard pick-and-place nozzles. The device's 1.37 g weight and symmetrical lead form ensure stable feeding and placement accuracy in high-volume automotive electronics assembly lines.

What is the reverse leakage current specification for MBRS2560CTH at elevated temperature?

At 125°C junction temperature and rated 60 V reverse voltage, MBRS2560CTH exhibits a maximum reverse leakage current (IR) of 10 mA per diode. This value is confirmed in the Electrical Specifications table and reflects worst-case behavior under sustained high-temperature operation. At 25°C, IR is limited to 200 µA max - a critical parameter for minimizing standby power loss in always-on automotive modules powered by MBRS2560CTH.

How does the guard ring feature improve reliability in MBRS2560CTH?

The guard ring in MBRS2560CTH is a diffused semiconductor structure surrounding the active junction that controls electric field distribution during overvoltage events. It prevents localized avalanche breakdown and edge-initiated failure during load dump transients (e.g., ISO 7637-2 Pulse 5a), extending device lifetime in automotive 12 V/24 V systems. This feature is verified in AEC-Q101 stress testing and directly contributes to MBRS2560CTH's ability to survive 200 A surge without parametric shift or catastrophic failure.
