Product details
Overview
MBRS1550CTH from Taiwan Semiconductor is a 15A, 50V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.75V forward voltage at 7.5A/25°C, 150A surge current capability, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the MBRS1550CTH datasheet, MBRS1550CTH pinout, MBRS1550CTH application, or MBRS1550CTH equivalent, key selection criteria include its 50V VRRM, dual-common-cathode configuration, 2°C/W junction-to-case thermal resistance, and J-STD-020 Level 1 moisture sensitivity rating.
Technical Context
This dual-die Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling synchronous rectification or dual-path low-loss conduction. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads ensure solderability per J-STD-002.
Designed for high-frequency switching environments, it delivers low power loss with 10,000 V/μs critical dv/dt rating and supports operation from –55°C to +150°C junction temperature, meeting automotive thermal and reliability requirements per AEC-Q101.
Key Specifications

| IF | 15 A - Continuous forward current per diode; supports sustained 15A conduction without derating at TC ≤ 90°C |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); handles motor startup or load dump transients |
| VF | 0.75 V @ 7.5A, 25°C - Low forward drop reduces conduction loss by >30% vs. silicon PN diodes at same current |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables efficient heat transfer to PCB copper or heatsink |
| TJ max | +150 °C - Maximum operating junction temperature; supports under-hood automotive placement |

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-15BQ050 | Same 50V VRRM, 15A IF, TO-263AB package; VF = 0.72V @ 7.5A, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial DC/DC where qualification is not mandated | Select when cost sensitivity outweighs AEC-Q101 requirement and thermal margin allows 0.03V higher VF |
| ON Semiconductor MBR1550CT | Identical electrical specs and TO-263AB package; AEC-Q101 qualified; marking differs (no "H" suffix), indicating different tape/reel packaging | Functionally identical performance; "H" suffix denotes halogen-free compound per IEC 61249-2-21 | Choose MBRS1550CTH when halogen-free compliance and J-STD-020 Level 1 moisture rating are mandatory |

FAQ
What is the maximum junction temperature rating for MBRS1550CTH?
The MBRS1550CTH has a maximum junction temperature (TJ) of +150°C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood environments and high-power-density DC/DC converters. Thermal design must maintain TJ ≤ 150°C using the specified RθJC = 2°C/W and appropriate PCB copper area. The MBRS1550CTH datasheet confirms this limit applies across its full voltage range (35–150V variants).
Is MBRS1550CTH pin-compatible with MBRS1545CTH or MBRS1560CTH?
Yes, MBRS1550CTH shares identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout with MBRS1545CTH and MBRS1560CTH. All variants feature Pin 1 (Anode 1), Pin 2 (Anode 2), and Pin 3 (Common Cathode). Voltage rating differences (45V/50V/60V) do not affect mechanical or electrical interface compatibility, enabling direct substitution where VRRM margin permits.
Does MBRS1550CTH require special handling for moisture sensitivity?
No-MBRS1550CTH is rated J-STD-020 Level 1, meaning it may be stored indefinitely at ambient conditions (<30°C/60% RH) without dry-pack or baking. This eliminates moisture-related popcorning risk during reflow, simplifying SMT line integration. The MBRS1550CTH specification sheet explicitly states Level 1 classification, confirming compatibility with standard JEDEC-compliant assembly processes.
What is the typical forward voltage of MBRS1550CTH at 15A and 125°C?
The MBRS1550CTH exhibits a typical forward voltage of 0.72V at IF = 15A and TJ = 125°C, as confirmed in the Electrical Specifications table of the official datasheet. This value reflects reduced VF drift at elevated temperature due to Schottky barrier physics, supporting stable performance in thermally constrained automotive modules where ambient temperatures exceed 85°C.
How does the guard ring feature improve reliability in MBRS1550CTH?
The guard ring in MBRS1550CTH enhances edge termination robustness against localized electric field crowding during transient overvoltage events-such as load dump or ISO 7637-2 pulses. This structural feature increases breakdown voltage margin beyond the rated 50V VRRM, reducing premature failure in noisy automotive power nets. The MBRS1550CTH datasheet cites guard ring inclusion as a key contributor to its AEC-Q101 qualification success.
