Taiwan Semiconductor Corporation MBRS1060CT-Y

Overview

MBRS1060CT-Y from Taiwan Semiconductor is a 10A, 60V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with 0.90V max forward voltage at 10A and 25°C, 120A surge capability, and junction-to-case thermal resistance of 2°C/W. It serves as a primary output rectifier in compact, high-frequency switching power supplies.

For engineers reviewing the MBRS1060CT-Y datasheet, MBRS1060CT-Y pinout, MBRS1060CT-Y application, or MBRS1060CT-Y equivalent, key selection criteria include reverse voltage rating (60V), forward voltage at full load, thermal performance under sustained conduction, and compatibility with automated SMT placement in high-density PCB layouts.

Technical Context

This dual-die common-cathode Schottky rectifier integrates two independent 10A diodes sharing one cathode terminal, enabling synchronous or interleaved rectification topologies. Its low V_F and fast recovery (<10ns) minimize conduction and switching losses in 100–500 kHz SMPS designs.

The TO-263AB package provides low thermal resistance (R_θJC = 2°C/W) and robust 120A non-repetitive surge current handling, supporting transient-heavy loads in adapters and industrial DC/DC modules without derating at moderate case temperatures.

FAQ

What is the maximum junction temperature rating for MBRS1060CT-Y?

The MBRS1060CT-Y has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows reliable operation in sealed enclosures or high-ambient environments when combined with its 2°C/W junction-to-case thermal resistance. Designers must ensure that actual T_J remains below 150°C under worst-case load and ambient conditions using thermal simulation or measurement. The MBRS1060CT-Y maintains specified electrical performance up to this limit.

Does MBRS1060CT-Y support lead-free reflow soldering?

Yes, MBRS1060CT-Y features matte tin-plated leads compliant with J-STD-002 for solderability, and its TO-263AB package is qualified for standard Pb-free reflow profiles (peak 260°C, 10-second duration). The device meets moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at room temperature without baking prior to assembly. No special handling or pre-bake steps are required for MBRS1060CT-Y in typical SMT production lines.

How does the guard ring feature benefit MBRS1060CT-Y in real-world applications?

The guard ring in MBRS1060CT-Y prevents premature edge breakdown under high dv/dt or localized electric field stress, improving long-term reliability in circuits with fast-switching MOSFETs or poor PCB layout. It ensures stable 60V reverse blocking even during voltage overshoot events (e.g., transformer leakage spikes or snubber ringing), reducing risk of catastrophic failure in SMPS and DC/DC converters. This structural enhancement is confirmed in TSC's mechanical and reliability test reports for the MBRS1060CT-Y family.

Can MBRS1060CT-Y be used in parallel configurations for higher current handling?

Yes, MBRS1060CT-Y supports parallel operation due to its positive temperature coefficient of forward voltage-ensuring natural current sharing between devices as temperature rises. For balanced loading, use matched trace lengths, symmetric thermal vias, and shared cathode copper pours. Each MBRS1060CT-Y contributes up to 10A continuous per die, so two devices yield up to 40A total in dual-die parallel mode. Thermal derating must follow the 2°C/W R_θJC and ambient constraints for the MBRS1060CT-Y.

What is the reverse leakage current specification for MBRS1060CT-Y at elevated temperature?

At 60V reverse voltage and 125°C junction temperature, the MBRS1060CT-Y exhibits a maximum reverse leakage current (I_R) of 10 mA, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value is critical for standby power budgeting in energy-efficient adapters and telecom systems. Leakage remains well below 100 µA at 25°C, confirming tight process control across the MBRS1060CT-Y production lot.
