Taiwan Semiconductor Corporation MBR1060

Overview

MBR1060 from Taiwan Semiconductor is a 10A, 60V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.80 V max at 10A/25°C), high surge current capability (150 A), and junction-to-case thermal resistance of 3°C/W. It serves as a primary output rectifier in high-efficiency DC-DC converters and AC-DC adapters.

For engineers reviewing the MBR1060 datasheet, MBR1060 pinout, MBR1060 application, or MBR1060 equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 10 mA reverse leakage at 125°C, AEC-Q101 qualification option (MBR1060H), and compatibility with standard TO-220AC heatsink mounting.

Technical Context

The MBR1060 operates as a single-die, unidirectional Schottky rectifier optimized for high-frequency switching applications. Its guard ring structure provides overvoltage protection, and it supports continuous forward current up to 10 A with derating above 25°C case temperature.

Thermal performance is defined by a 3°C/W junction-to-case resistance and a maximum junction temperature of 150°C. The device exhibits 100 µA reverse current at 25°C and 10 mA at 125°C under rated 60 V reverse bias, enabling stable operation in thermally constrained power stages.

FAQ

What is the maximum junction temperature rating for MBR1060?

The MBR1060 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in Taiwan Semiconductor's M2103 datasheet. This allows sustained operation in high-ambient environments such as enclosed power supplies or industrial enclosures. Derating begins above 25°C case temperature, and thermal design must maintain T_J ≤ 150°C under worst-case load and ambient conditions. The MBR1060 achieves this via its 3°C/W R_θJC and TO-220AC package interface.

Does MBR1060 have AEC-Q101 qualification?

The base MBR1060 is not AEC-Q101 qualified; however, the MBR1060H variant is explicitly listed as AEC-Q101 qualified in Taiwan Semiconductor's ordering information. The "H" suffix denotes automotive-grade screening and test compliance. For automotive infotainment or body-control module designs, MBR1060H-not MBR1060-must be specified to meet AEC-Q101 requirements. Both share identical electrical specs and TO-220AC packaging.

What is the forward voltage of MBR1060 at 10A and 125°C?

The MBR1060 exhibits a maximum forward voltage (V_F) of 0.70 V at 10 A and 125°C junction temperature, per the Electrical Specifications table in the M2103 datasheet. This value is critical for thermal modeling in high-temperature operation, as it directly impacts conduction loss and self-heating. At 25°C, V_F is rated ≤ 0.80 V under the same current condition.

Is MBR1060 compatible with lead-free reflow soldering?

Yes, the MBR1060 features matte tin-plated leads that are solderable per J-STD-002 and compatible with lead-free reflow processes. Its molding compound meets UL 94V-0 flammability rating, and the device passes JESD201 Class 2 whisker testing-ensuring reliability under thermal cycling and RoHS-compliant assembly. Peak reflow temperature must remain within JEDEC Level 1 limits for TO-220AC packages.

What is the reverse leakage current of MBR1060 at elevated temperature?

At 125°C junction temperature and rated 60 V reverse voltage, the MBR1060 exhibits a maximum reverse leakage current (I_R) of 10 mA, as specified in the Electrical Specifications table. This is significantly higher than its 100 µA rating at 25°C, reflecting typical Schottky behavior. Designers must account for this increase in standby power loss and thermal runaway risk in high-temperature, high-voltage hold-off applications.
