Product details
Overview
MBRS20150CTH from Taiwan Semiconductor is a 20A dual common-cathode Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 150V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C; it delivers 1.23V forward voltage at 20A/25°C and is qualified to AEC-Q101 for automotive-grade reliability.
For engineers reviewing the MBRS20150CTH datasheet, MBRS20150CTH pinout, MBRS20150CTH application, or MBRS20150CTH equivalent, key selection considerations include its 150V VRRM rating, 2.0°C/W junction-to-case thermal resistance, low 5mA reverse leakage at 125°C, guard ring overvoltage protection, and suitability for high-frequency DC/DC converters and reverse battery protection circuits.
Technical Context
This device integrates two independent Schottky diodes in a single common-cathode configuration, enabling synchronous rectification or dual-path freewheeling in compact power topologies. Its 150V VRRM rating supports higher bus voltages than lower-voltage variants (e.g., MBRS2060CTH), while maintaining low conduction loss via optimized metal-semiconductor junction design.
The TO-263AB package provides enhanced thermal performance with 2.0°C/W RθJC, supporting continuous 20A operation under forced-air or PCB copper thermal management. Guard ring structure and JESD201 Class 2 whisker resistance ensure robustness in automotive environments where transient overvoltage and mechanical stress are critical.

FAQ
What is the maximum junction temperature rating for MBRS20150CTH?
The MBRS20150CTH has a maximum junction temperature (TJ) of +150°C, validated across its full operating range and confirmed in thermal performance testing. This rating allows sustained operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design meets the 2.0°C/W RθJC specification. The MBRS20150CTH must be mounted on adequate PCB copper area or heatsink to maintain safe junction temperature under 20A load.
Is MBRS20150CTH suitable for reverse battery protection in 12V automotive systems?
Yes, MBRS20150CTH is widely used for reverse battery protection due to its 150V VRRM rating-providing ample margin above 12V system transients-and its AEC-Q101 qualification. Its low 1.23V forward voltage at 20A minimizes insertion loss, and the guard ring structure enhances robustness against voltage spikes during incorrect connection. The MBRS20150CTH is specified for this use in Taiwan Semiconductor's official application guidance.
What is the forward voltage of MBRS20150CTH at 20A and 125°C?
The MBRS20150CTH exhibits a maximum forward voltage of 1.10 V at 20A and 125°C, as specified in the Electrical Specifications table. This value reflects real-world performance under high-temperature operating conditions typical in automotive power modules. Designers should use this figure-not the 25°C value-for thermal modeling and efficiency calculations in hot-environment applications involving the MBRS20150CTH.
Does MBRS20150CTH have a common-cathode configuration?
Yes, MBRS20150CTH uses a dual common-cathode configuration: Pins 1 and 2 are independent anodes, and Pin 3 is the shared cathode. This architecture enables compact implementation of dual-output power supplies or interleaved converters without external wiring. The common-cathode layout is explicitly defined in the Marking Diagram and Package Outline Dimensions section of the MBRS20150CTH datasheet.
What packaging and reel quantity does MBRS20150CTH ship in?
MBRS20150CTH is supplied in TO-263AB (D2PAK) package and shipped in tape-and-reel format with 800 units per reel, as documented in the Ordering Information section. The device features matte tin-plated leads compliant with J-STD-002 solderability standards and moisture sensitivity level 1 per J-STD-020-enabling unlimited floor life and compatibility with standard SMT reflow processes without baking.
