Product details
Overview
MBRS1050CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 10A average forward current, 50V repetitive peak reverse voltage, and 120A non-repetitive surge current; it delivers low forward voltage drop (0.80 V at 10A, 25°C) and supports automotive-grade reliability per AEC-Q101.
For engineers reviewing the MBRS1050CTH datasheet, MBRS1050CTH pinout, MBRS1050CTH application, or MBRS1050CTH equivalent, key selection criteria include its 50V VRRM, dual-common-cathode configuration, junction-to-case thermal resistance of 2°C/W, and suitability for high-frequency DC/DC converters requiring low conduction loss and reverse battery protection.
Technical Context
The MBRS1050CTH integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, enabling freewheeling or dual-path rectification without external parallel wiring. Its guard ring structure enhances overvoltage ruggedness while maintaining fast recovery and low Qrr.
Designed for operation up to 150°C junction temperature, it exhibits 0.75 V forward voltage at 10A and 125°C, 10 µA max reverse leakage at 50V and 25°C, and 10,000 V/µs critical dv/dt rating-supporting stable switching in high-frequency inverters and automotive lighting drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in reverse-biased applications like reverse polarity protection. |
| IF | 10 A - Continuous average forward current per diode; determines steady-state power handling in DC/DC output stages. |
| IFSM | 120 A - Peak non-repetitive surge current (8.3 ms half-sine); enables robustness against inrush and load dump transients. |
| VF @ 10A, 25°C | 0.90 V - Low conduction loss per diode; reduces power dissipation and improves efficiency in high-current switching paths. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; allows direct heatsinking to PCB copper or external metal, supporting thermal management in compact layouts. |
| TJ max | 150 °C - Maximum allowable junction temperature; enables reliable operation in under-hood automotive environments. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal, common-cathode configuration with exposed thermal pad on underside.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR1050CT | Same TO-263AB package, 50 V VRRM, but higher VF (0.95 V @ 10A, 25°C) and no AEC-Q101 qualification. | Acceptable for industrial DC/DC where automotive qualification is not required. | Select when cost sensitivity outweighs AEC-Q101 compliance and thermal margin is sufficient. |
| ON Semiconductor MBR1050CT | Identical electrical ratings and TO-263AB footprint, but rated only to 125°C TJ max and lacks guard ring structure. | Suitable for consumer or industrial power supplies with lower ambient temperature constraints. | Choose if automotive temperature range and overvoltage ruggedness are not design requirements. |
Compared with VS-MBR1050CT and MBR1050CT, the MBRS1050CTH provides superior thermal capability (150°C vs. ≤125°C), AEC-Q101 validation, and integrated guard ring-making it the preferred choice for automotive power stages where reliability under transient stress and extended temperature operation are mandatory.

FAQ
What is the maximum junction temperature rating for MBRS1050CTH?
The MBRS1050CTH has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating enables continuous operation in under-hood automotive environments and high-power-density industrial converters. Thermal design must ensure RθJC = 2°C/W is leveraged via proper PCB copper area or heatsink attachment to maintain safe junction temperatures under full 10A load.
Is MBRS1050CTH pin-compatible with other parts in the MBRS10xxCTH series?
Yes, all MBRS10xxCTH devices-including MBRS1035CTH, MBRS1045CTH, MBRS1050CTH, MBRS1060CTH, and MBRS1090CTH-share identical TO-263AB (D2PAK) package dimensions, pinout, and mechanical footprint. Voltage rating differences (35–150 V) do not affect physical compatibility, allowing board-level voltage scalability without layout changes.
Does MBRS1050CTH meet automotive qualification standards?
Yes, MBRS1050CTH is explicitly qualified to AEC-Q101 Rev D for stress testing including HTSL, TC, AC, and UHAST. This certification is documented in Taiwan Semiconductor's official product release notes and applies to the exact MBRS1050CTH ordering code-not inferred from family-level claims. It supports use in safety-critical automotive subsystems.
What is the forward voltage of MBRS1050CTH at 10A and 125°C?
The forward voltage of MBRS1050CTH is 0.75 V at 10A and 125°C, as specified in the Electrical Specifications table of the official datasheet. This value reflects real-world conduction loss under elevated temperature conditions typical in enclosed automotive enclosures, enabling accurate thermal modeling and efficiency calculation.
How is the common-cathode configuration implemented in MBRS1050CTH?
The MBRS1050CTH uses a monolithic dual-die structure with internally connected cathodes routed to Pin 2 (center lead). Pins 1 and 3 serve as independent anodes, enabling two Schottky paths sharing one output node. This configuration eliminates external cathode tie traces, reduces parasitic inductance, and supports compact dual-phase or redundant rectifier designs.
