Product details
Overview
MBR1090CT from Taiwan Semiconductor is a 10A dual-die Schottky barrier rectifier in TO-220AB package, rated for 90V repetitive peak reverse voltage (VRRM), 0.95V max forward voltage at 10A/25°C, and 120A non-repetitive surge current-used in high-efficiency DC-DC converters and industrial SMPS where low conduction loss and thermal robustness are critical.
For engineers reviewing the MBR1090CT datasheet, MBR1090CT pinout, MBR1090CT application, or MBR1090CT equivalent, key selection criteria include verified VRRM=90V, dual-common-cathode configuration, RθJC=1.5°C/W thermal resistance, TJ max=150°C operation, and AEC-Q101 qualification availability in related variants.
Technical Context
The MBR1090CT integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling full-wave rectification or dual-channel output paths. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
Designed for switching frequencies up to 20 kHz, it delivers stable forward conduction down to TJ = –55°C and supports pulsed surge currents up to 120A (8.3 ms half-sine) without degradation. Thermal performance is characterized by a junction-to-case resistance of 1.5°C/W, enabling direct heatsink mounting under 10A continuous load.

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 TO-220AB package, same 90V VRRM and 10A IF, but VF = 0.92V typ @ 10A/25°C (vs. 0.95V max for MBR1090CT) | No functional substitution limitation; compatible in all PCB layouts using TO-220AB footprint | Select for marginally lower conduction loss where Vishay's tighter VF distribution is preferred |
| ON Semiconductor MBR1090CT | Same electrical specs and package; differs in marking layout and minor thermal resistance (RθJC = 1.6°C/W vs. 1.5°C/W) | Valid for industrial and consumer designs; not AEC-Q101 qualified unless specified as MBR1090CTH | Choose when sourcing flexibility across multiple franchised distributors is prioritized over Taiwan Semiconductor's specific qualification path |
Compared with VS-MBR1090CT and ON Semi MBR1090CT, the Taiwan Semiconductor MBR1090CT offers the lowest published RθJC (1.5°C/W), enabling higher sustained current in space-constrained heatsink designs, while maintaining identical pinout, voltage rating, and surge capability.

FAQ
What is the maximum junction temperature rating for the MBR1090CT?
The MBR1090CT has a maximum junction temperature (TJ max) of +150°C, allowing continuous operation in high-ambient environments such as enclosed industrial power supplies or LED driver housings. This rating is validated per JEDEC standards and supported by its 1.5°C/W junction-to-case thermal resistance. Derating curves in the official TSC datasheet confirm usable current capacity down to –55°C storage temperature.
Does the MBR1090CT have AEC-Q101 qualification?
The base MBR1090CT is not AEC-Q101 qualified; however, the variant MBR1090CTH-identical in electrical and mechanical specifications-is explicitly qualified per AEC-Q101 for automotive applications. The "H" suffix denotes qualification, including stress testing for temperature cycling, humidity bias, and mechanical shock. Always verify the full ordering code before automotive use.
What is the forward voltage specification for MBR1090CT at 10A and 125°C?
Per the Taiwan Semiconductor datasheet, the MBR1090CT exhibits a maximum forward voltage (VF) of 0.85 V at 10A and TJ = 125°C. This value reflects real-world thermal performance in high-temperature operation and is critical for calculating conduction losses in thermally constrained designs such as sealed LED drivers or fanless industrial PSUs.
How is the pin configuration arranged on the MBR1090CT TO-220AB package?
The MBR1090CT uses a standard TO-220AB 3-pin layout: Pin 1 (left lead) is Anode 1, Pin 2 (center lead and metal tab) is the common cathode, and Pin 3 (right lead) is Anode 2. Polarity is marked on the device body, and the tab is electrically connected to the cathode-requiring insulation if mounted to a grounded heatsink.
What is the reverse leakage current of MBR1090CT at rated voltage and elevated temperature?
At 90V reverse voltage and TJ = 25°C, the MBR1090CT specifies a maximum reverse current (IR) of 100 µA per diode. At TJ = 125°C and VR = 90V, IR rises to 2 mA max-critical for standby power budgeting in always-on systems like smart meters or IoT gateways where cumulative leakage impacts total system quiescent draw.
