Taiwan Semiconductor Corporation MBRS10150

Overview

MBRS10150 from Taiwan Semiconductor is a 10A, 150V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, designed for high-efficiency DC/DC conversion and switching-mode power supplies. It features 1.05V forward voltage at 10A/25°C, 120A surge capability, 175°C max junction temperature, and guard-ring overvoltage protection.

For engineers reviewing the MBRS10150 datasheet, MBRS10150 pinout, MBRS10150 application, or MBRS10150 equivalent, key selection criteria include reverse voltage rating, thermal resistance (R_θJC = 2°C/W), forward voltage at operating current, surge robustness, and RoHS/halogen-free compliance for industrial power designs.

Technical Context

The MBRS10150 is a single-die, unidirectional Schottky rectifier optimized for low-loss freewheeling and output rectification in high-frequency SMPS topologies. Its 150V V_RRM rating enables use in 48V–60V bus systems with margin, while its 2°C/W junction-to-case thermal resistance supports high-power density layouts with minimal heatsinking.

It operates across -55°C to +175°C junction temperature range and exhibits 5mA reverse leakage at 150V and 125°C. The device uses matte tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance.

FAQ

What is the maximum junction temperature rating for the MBRS10150?

The MBRS10150 has a maximum junction temperature (T_J) of 175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows continuous operation in high-ambient environments such as enclosed industrial enclosures or automotive under-hood auxiliary supplies. Thermal design must ensure that actual junction temperature stays below this limit using the specified R_θJC = 2°C/W and appropriate PCB copper area.

Does the MBRS10150 have a guard ring structure, and what is its function?

Yes, the MBRS10150 incorporates a guard ring structure, explicitly listed in its features. This design enhances edge termination robustness against high dv/dt stress (rated ≥10,000 V/μs), preventing premature avalanche breakdown at the silicon periphery during fast-switching transients common in LLC and phase-shifted full-bridge converters. It directly improves long-term reliability in high-frequency power supplies.

What is the forward voltage of the MBRS10150 at 10A and 125°C?

The MBRS10150 datasheet does not specify forward voltage at 10A and 125°C; only values for MBRS1035–MBRS10100 are provided in that condition. At 25°C and 10A, V_F is 1.05V (max). For thermal design at elevated temperatures, engineers should apply typical V_F temperature coefficients from similar Schottky devices or perform empirical validation, as the MBRS10150's V_F behavior above 100°C is not characterized in published specs.

Is the MBRS10150 RoHS and halogen-free compliant?

Yes, the MBRS10150 is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. This compliance supports environmental requirements for industrial, telecom, and consumer equipment sold in EU, China, and other regulated markets, and eliminates corrosive halogen compounds during soldering and end-of-life processing.

What is the moisture sensitivity level (MSL) of the MBRS10150, and how does it affect assembly?

The MBRS10150 has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not sensitive to moisture and requires no baking or dry-pack handling before surface-mount reflow. This simplifies manufacturing logistics, reduces process steps, and eliminates risk of popcorning during standard lead-free reflow profiles-ideal for high-volume automated placement lines.
