Product details
Overview
MBRS1090CT from Taiwan Semiconductor is a 10A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 90V repetitive peak reverse voltage (VRRM), 0.95V max forward voltage at 10A/25°C, and 120A surge current capability-designed for high-efficiency DC–DC converters and switching power supplies.
For engineers reviewing the MBRS1090CT datasheet, MBRS1090CT pinout, MBRS1090CT application, or MBRS1090CT equivalent, key selection criteria include VRRM=90V, IF=10A continuous, VF≤0.95V @10A/25°C, RθJC=2°C/W thermal resistance, and TO-263AB package compatibility with high-power surface-mount layouts.
Technical Context
The MBRS1090CT integrates two independent Schottky diodes in a single TO-263AB thermally optimized package, enabling dual-channel synchronous rectification or independent output paths. Its low VF and high IFSM support high-frequency switching topologies with minimal conduction loss and robust transient handling.
Designed for operation up to TJ=150°C, it features guard ring overvoltage protection, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1-ensuring reliability in automated SMT assembly and industrial-grade power conversion environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum non-repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or buck-boost clamp circuits |
| IF | 10 A - Continuous forward current per diode; supports sustained 10A DC output in dual-rail or parallel-configured SMPS |
| VF (max) | 0.95 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V→5V/3.3V DC–DC stages |
| IFSM | 120 A - Peak non-repetitive surge current; withstands inrush and fault transients without bond-wire failure |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; allows direct heatsinking to PCB copper or external metal slug for thermal management |
| IR (max) | 100 µA @ 90V, 25°C - Low leakage preserves standby efficiency in always-on power rails |
| TJ max | 150 °C - Maximum junction temperature; enables operation in enclosed industrial enclosures without forced air |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with common cathode connection. Case serves as thermal and electrical cathode node.
| Pin/Terminal | Circuit Role | Design Meaning |

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-MBR1090CT | Identical VRRM=90V, IF=10A, TO-263AB package; VF=0.92V typ @10A/25°C (slightly lower conduction loss) | No functional difference; validated in same SMPS reference designs | Drop-in alternative with identical pinout and thermal profile; preferred where <0.03V VF reduction improves thermal margin |
| ON Semiconductor MBR1090CT | VRRM=90V, IF=10A, TO-220AC package (not D2PAK); RθJC=3.5°C/W vs. MBRS1090CT's 2°C/W | Requires PCB redesign due to different footprint and thermal interface; higher thermal resistance limits power density | Only suitable when TO-220 mounting and lower-cost through-hole assembly are prioritized over surface-mount thermal performance |
Compared with VS-MBR1090CT, MBRS1090CT offers marginally higher VF but identical reliability specs and qualification; compared with MBR1090CT, MBRS1090CT provides superior thermal performance and SMT compatibility-critical for high-density power modules.

FAQ
What is the maximum junction temperature rating for MBRS1090CT?
The MBRS1090CT has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows continuous operation in high-ambient industrial environments. Derating curves confirm usable current capacity down to 5A at 125°C case temperature. Thermal design must maintain TJ ≤ 150°C using the specified RθJC = 2°C/W path to ensure long-term reliability of MBRS1090CT.
Is MBRS1090CT pin-compatible with MBRS10100CT?
Yes, MBRS1090CT is pin-compatible with MBRS10100CT because both belong to the same TO-263AB (D2PAK) dual-anode common-cathode family and share identical mechanical outline, terminal assignment, and marking orientation. The only difference is VRRM rating (90V vs. 100V), so MBRS1090CT can be used in designs originally specifying MBRS10100CT if 90V blocking suffices-no PCB changes required for MBRS1090CT substitution.
What is the typical forward voltage of MBRS1090CT at 10A and 125°C?
The typical forward voltage of MBRS1090CT at 10A and 125°C is 0.85V, per Taiwan Semiconductor's Electrical Specifications table. This value reflects reduced VF at elevated temperature due to Schottky diode physics and is critical for thermal runaway analysis. The datasheet specifies a maximum of 0.95V at 25°C and 0.85V typical at 125°C-both confirmed for MBRS1090CT under pulsed test conditions (PW = 0.3ms).
Does MBRS1090CT have a guard ring structure?
Yes, MBRS1090CT incorporates a guard ring structure as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This design enhances edge termination robustness, improving resistance to avalanche-induced degradation and extending device lifetime under repetitive overvoltage stress-particularly beneficial in flyback and LLC resonant converter applications where voltage spikes occur regularly during MBRS1090CT operation.
What packaging format is available for MBRS1090CT?
MBRS1090CT is supplied in TO-263AB (D2PAK) package on 800-unit tape-and-reel format, per the Ordering Information section of the Taiwan Semiconductor datasheet. The tape complies with EIA-481 standards, and the reel diameter is 330 mm. No tray or tube options are listed for MBRS1090CT; all commercial volumes ship in this SMT-ready configuration to support high-speed pick-and-place assembly of MBRS1090CT.
