Product details
Overview
MBRS2050CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20 A average forward current, 50 V repetitive peak reverse voltage, and 150 A surge current. It delivers low forward voltage drop (0.80 V max at 10 A, 25°C) and high thermal performance (RθJC = 1.5 °C/W), making it suitable for DC/DC converters in automotive lighting systems.
For engineers reviewing the MBRS2050CTH datasheet, MBRS2050CTH pinout, MBRS2050CTH application, or MBRS2050CTH equivalent, key selection criteria include its AEC-Q101 qualification, 150°C maximum junction temperature, moisture sensitivity level 1 rating, and dual-die configuration enabling independent cathode/anode routing in freewheeling and reverse battery protection circuits.
Technical Context
The MBRS2050CTH integrates two identical Schottky diodes in a single TO-263AB surface-mount package with common cathode configuration (dual cathode, single anode per die). Its guard ring structure provides overvoltage protection, while matte tin-plated leads ensure solderability per J-STD-002.
Designed for high-frequency switching applications, it supports 10,000 V/μs critical rate of rise of off-state voltage and exhibits low reverse leakage (≤10 mA at 125°C, rated VR), enabling stable operation in 20 kHz square-wave DC/DC topologies with minimal conduction loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in reverse-biased freewheeling paths |

| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); withstands load dump transients in vehicle electrical systems |
| VF (max) | 0.80 V @ 10 A, 25°C - Low conduction loss reduces heat generation and improves system efficiency above 90% |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance enables direct heatsinking to PCB copper or external metal slugs |
| TJ max | +150°C - Extended junction temperature rating allows operation in under-hood automotive environments |

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-MBR2050CT | Same TO-263AB package, 50 V VRRM, but higher VF (0.92 V max @ 10 A, 25°C) and RθJC = 2.0 °C/W | Limited to lower ambient temperature environments due to reduced thermal efficiency | Prefer MBRS2050CTH where board-level thermal management is constrained |
| ON Semiconductor MBR2050CT | Identical electrical ratings but lacks AEC-Q101 qualification and has MSL Level 3 handling requirement | Not recommended for automotive production; suitable only for industrial prototypes or non-safety-critical systems | Select MBRS2050CTH for production automotive designs requiring certified reliability and simplified assembly |
Compared with VS-MBR2050CT and MBR2050CT, the MBRS2050CTH offers superior thermal performance (1.5 vs. 2.0 °C/W), lower forward voltage, and full AEC-Q101 compliance-making it the preferred choice for thermally dense, automotive-qualified power stages.

FAQ
What is the maximum junction temperature rating for MBRS2050CTH?
The MBRS2050CTH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows continuous operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using the specified RθJC = 1.5 °C/W path.
Is MBRS2050CTH pin-compatible with other parts in the MBRS20xCTH family?
Yes, all MBRS20xCTH variants-including MBRS2035CTH, MBRS2045CTH, MBRS2050CTH, MBRS2060CTH, MBRS2090CTH, MBRS20100CTH, and MBRS20150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. Voltage rating differences do not affect mechanical or electrical footprint compatibility.
Does MBRS2050CTH require special handling for moisture sensitivity?
No. The MBRS2050CTH is rated Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life and can be processed using standard reflow profiles without baking or dry-pack requirements-unlike MSL 3 or higher components that demand strict humidity control.
What is the typical forward voltage of MBRS2050CTH at 20 A and 125°C?
At 20 A forward current and 125°C junction temperature, the MBRS2050CTH exhibits a maximum forward voltage (VF) of 0.85 V, as specified in the Electrical Specifications table. This value reflects real-world conduction loss under high-load, high-temperature conditions typical in automotive DC/DC converters.
How does the guard ring feature benefit MBRS2050CTH in automotive applications?
The guard ring in MBRS2050CTH enhances edge termination robustness, improving resistance to localized electric field concentration during voltage transients. In automotive systems, this mitigates premature breakdown during load dump or jump-start events-reducing need for external TVS clamping and increasing system-level reliability without added bill-of-materials cost.
