Product details
Overview
MBRS2090CT from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 90V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.85 V max at 10 A, 25°C) and is optimized for high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the MBRS2090CT datasheet, MBRS2090CT pinout, MBRS2090CT application, or MBRS2090CT equivalent, key selection criteria include its 90 V VRRM, dual-common-cathode configuration, 2.0 °C/W junction-to-case thermal resistance, and suitability for automated SMT placement in high-density power stages.
Technical Context
The MBRS2090CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection. Its design targets high-frequency switching applications where low forward voltage and fast recovery are critical to minimize conduction loss and eliminate reverse recovery charge.
It features guard ring protection for overvoltage robustness, meets JESD201 Class 2 whisker resistance, and is rated for moisture sensitivity level 1 per J-STD-020 - enabling reflow compatibility without dry-pack handling. Thermal performance is characterized by RθJC = 2.0 °C/W for the 90–150 V variants.
Key Specifications

FAQ
What is the maximum junction temperature rating for MBRS2090CT?
The MBRS2090CT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version N2103). This allows sustained operation in thermally demanding environments such as enclosed industrial power modules or high-ambient telecom equipment. Derating curves confirm usable current capacity down to 12 A at 125°C case temperature.
Does MBRS2090CT support automated pick-and-place assembly?
Yes, MBRS2090CT is qualified for automated placement per its mechanical data: TO-263AB (D2PAK) package with matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), and lead coplanarity ≤0.15 mm. Its standardized tape-and-reel packaging (800 units per reel) and robust terminal finish ensure reliable feeding and placement in high-speed SMT lines without pre-baking.
What is the forward voltage specification of MBRS2090CT at full rated current?
At 20 A forward current and 25°C junction temperature, the MBRS2090CT exhibits a maximum forward voltage (VF) of 0.95 V per diode, as specified in the Electrical Specifications table. At 125°C, this increases to 0.85 V max - confirming stable low-loss performance across its full operating temperature range.
Is MBRS2090CT halogen-free and RoHS compliant?
Yes, MBRS2090CT is both halogen-free per IEC 61249-2-21 and RoHS compliant, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version N2103). The molding compound contains no brominated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU limits for restricted substances.
How does the guard ring feature benefit MBRS2090CT in real-world applications?
The integrated guard ring in MBRS2090CT enhances edge termination robustness, suppressing premature avalanche breakdown under voltage transients. In practice, this improves reliability in SMPS outputs subjected to line surges or inductive switching noise - reducing field failure rates in industrial adapters and telecom rectifiers without requiring external TVS clamping.
