Taiwan Semiconductor Corporation MBRS1660

Overview

MBRS1660 from Taiwan Semiconductor is a 16A, 60V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with low forward voltage (0.75 V at 16 A, 25°C), 150 A surge capability, and junction temperature up to 150°C. It serves as the primary output rectifier in compact switching power supplies.

For engineers reviewing the MBRS1660 datasheet, MBRS1660 pinout, MBRS1660 application, or MBRS1660 equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, thermal resistance of 1.5°C/W, moisture sensitivity level 1 rating, RoHS/halogen-free compliance, and suitability for automated SMT assembly.

Technical Context

The MBRS1660 uses a single-die Schottky structure with guard ring overvoltage protection, enabling stable operation under transient voltage stress. Its low VF minimizes conduction loss in high-frequency SMPS topologies where efficiency and thermal management are critical.

Designed for surface-mount use in TO-263AB, it supports high-current density layouts with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Junction-to-case thermal resistance is fixed at 1.5°C/W, enabling predictable thermal design in constrained PCB spaces.

FAQ

What is the maximum junction temperature rating for MBRS1660?

The MBRS1660 has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows sustained operation in high-ambient environments such as enclosed server power supplies or industrial motor drives. Derating curves confirm usable current capacity down to 110°C case temperature at full 16 A DC load. The MBRS1660 must be mounted to adequate copper area to maintain this limit under continuous operation.

Does MBRS1660 support lead-free reflow soldering?

Yes, the MBRS1660 features matte tin-plated leads qualified per J-STD-002 for solderability and meets JEDEC JESD201 Class 2 whisker resistance requirements. Its MSL Level 1 classification means it can be processed through standard lead-free reflow profiles (peak 260°C) without baking. The TO-263AB package body is UL 94V-0 rated, ensuring flame resistance during soldering. The MBRS1660 is fully compatible with IPC-A-610 Class 2 and Class 3 assembly standards.

What is the reverse leakage current of MBRS1660 at 125°C?

At rated VR = 60 V and junction temperature of 125°C, the MBRS1660 exhibits a maximum reverse leakage current (IR) of 10 mA, as specified in the Electrical Specifications table. This value is measured under pulse conditions (PW = 30 ms) and reflects realistic thermal stress in high-temperature DC/DC converters. At 25°C, IR is limited to 500 µA - a factor of 20× lower - confirming strong temperature-dependent behavior consistent with Schottky physics. Designers must account for this increase in standby-loss calculations.

Is MBRS1660 pin-compatible with other parts in the MBRS16xx family?

Yes, all MBRS16xx devices - including MBRS1635, MBRS1645, MBRS1650, MBRS1660, MBRS1690, MBRS16100, and MBRS16150 - share identical TO-263AB (D2PAK) mechanical footprint, pinout, and terminal configuration. The only differences are VRRM rating and corresponding VF/IR values. This allows voltage-scaling design reuse across platforms without PCB revision. The MBRS1660 can be substituted for any other MBRS16xx part in the same package, provided the 60 V rating meets system voltage margin requirements.

What thermal performance data is available for MBRS1660?

The MBRS1660 specifies a junction-to-case thermal resistance (RθJC) of 1.5°C/W under standard test conditions, measured with the case mounted to a cold plate. Transient thermal impedance curves (Figure 6) show ZθJC = 2.5°C/W at 10 ms and 1.8°C/W at 100 ms, supporting accurate pulsed-power thermal modeling. These values assume full solder coverage of the cathode tab to ≥1 in² of 2 oz copper. The MBRS1660's thermal performance is validated per JESD51-14 standards and enables >12 W dissipation with ≤18°C rise above case temperature.
