Taiwan Semiconductor Corporation MBRS1660H

Overview

MBRS1660H from Taiwan Semiconductor is a 16A, 60V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring low forward voltage (0.75 V at 16 A, 25°C), high surge current capability (150 A), and AEC-Q101 qualification for automotive use. It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.

For engineers reviewing the MBRS1660H datasheet, MBRS1660H pinout, MBRS1660H application, or MBRS1660H equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 1.5 °C/W junction-to-case thermal resistance, 10 mA reverse leakage at 125°C, TO-263AB mechanical compatibility, and AEC-Q101 stress qualification status.

Technical Context

The MBRS1660H uses a single-die Schottky structure optimized for low conduction loss in high-frequency switching applications. Its guard ring design enhances overvoltage robustness, and its matte tin-plated leads meet J-STD-002 solderability requirements with MSL Level 1 moisture sensitivity.

Thermally, it delivers 1.5 °C/W junction-to-case resistance and operates across –55°C to +150°C junction temperature range. The device is rated for 32 A peak repetitive forward current under square-wave 20 kHz conditions and withstands 8.3 ms half-sine surges up to 150 A.

FAQ

What is the maximum junction temperature rating for MBRS1660H?

The MBRS1660H has a maximum junction temperature (T_J) of +150°C, validated across its full operating range from –55°C to +150°C. This rating is confirmed in the Absolute Maximum Ratings table and supported by AEC-Q101 thermal stress testing. The device maintains specified electrical performance-including 0.75 V forward voltage and 10 mA reverse leakage at 125°C-within this envelope. Engineers designing for underhood automotive environments must ensure PCB heatsinking keeps T_J ≤ 150°C under worst-case ambient and power dissipation conditions.

Is MBRS1660H pin-compatible with other parts in the MBRS16xH series?

Yes, all MBRS16xH variants-including MBRS1635H, MBRS1645H, MBRS1650H, MBRS1660H, MBRS1690H, MBRS16100H, and MBRS16150H-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. The only differences are V_RRM (35 V to 150 V) and corresponding forward voltage/reverse leakage values. This allows direct voltage-rating substitution on the same PCB footprint without layout changes, provided thermal and surge margins remain acceptable for the new rating.

Does MBRS1660H require special handling during PCB assembly?

No, MBRS1660H is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without baking or dry-packaging. Its matte tin-plated leads comply with J-STD-002 for solderability, and the TO-263AB package is optimized for automated pick-and-place. No special stencil design or thermal profiling beyond typical D2PAK guidelines is needed for reliable assembly of MBRS1660H.

What is the reverse leakage current of MBRS1660H at elevated temperature?

At T_J = 125°C and rated V_R = 60 V, the MBRS1660H exhibits a maximum reverse leakage current (I_R) of 10 mA, as specified in the Electrical Specifications table. This value is measured under 30 ms pulse conditions and reflects worst-case behavior in high-temperature automotive environments. At 25°C, leakage is limited to 500 µA-enabling low-quiescent-power operation in always-on systems such as telematics or body control modules.

How does the guard ring feature improve reliability in MBRS1660H?

The guard ring in MBRS1660H is a diffusion-based edge termination structure that controls electric field distribution at the silicon periphery. It prevents premature avalanche breakdown during transient overvoltage events-such as ISO 7637-2 Load Dump pulses-by reducing peak field intensity at the junction edge. This directly extends device lifetime in automotive applications and eliminates need for external TVS clamping in many 12 V/24 V reverse-protection and freewheeling configurations, simplifying BOM and layout.
