Product details
Overview
MBR1090CTH from Taiwan Semiconductor is a 10A dual-die Schottky barrier rectifier in TO-220AB package, rated for 90V repetitive peak reverse voltage (VRRM), with forward voltage of 0.95V at 10A/25°C and 0.85V at 10A/125°C, used in high-efficiency DC–DC converters and automotive-grade power supplies.
For engineers reviewing the MBR1090CTH datasheet, MBR1090CTH pinout, MBR1090CTH application, or MBR1090CTH equivalent, key selection criteria include its AEC-Q101 qualification, 120A surge capability, 1.5°C/W junction-to-case thermal resistance, and low reverse leakage of 2mA at 125°C - critical for thermally constrained, high-reliability power conversion designs.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 10A diodes in a single TO-220AB thermally robust package, enabling synchronous or interleaved rectification topologies. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads ensure reliable solderability per J-STD-002.
The device operates across –55°C to +150°C junction temperature range, supports 10,000 V/μs critical dv/dt rating, and delivers stable performance under 8.3ms half-sine surge conditions up to 120A - making it suitable for transient-heavy industrial and automotive power rails.
Key Specifications

FAQ
What is the maximum junction temperature rating for the MBR1090CTH?
The MBR1090CTH has a maximum junction temperature (TJ) rating of +150°C, with operational capability down to –55°C. This wide range supports deployment in under-hood automotive locations and industrial enclosures without forced cooling, provided thermal design maintains TJ within limits using the specified 1.5°C/W RθJC.
Is the MBR1090CTH pin-compatible with standard TO-220AB dual-diode rectifiers?
Yes, the MBR1090CTH uses the industry-standard TO-220AB outline with 3-pin dual-common-cathode configuration: Pin 1 (Anode 1), Pin 2 (Common Cathode/Tab), Pin 3 (Anode 2). It mates with standard TO-220 heatsinks and PCB footprints used for MBR10xxCT-series devices.
Does the "H" suffix in MBR1090CTH indicate AEC-Q101 qualification?
Yes - per Taiwan Semiconductor's ordering information, the "H" suffix explicitly denotes AEC-Q101 qualification. The MBR1090CTH has undergone full stress testing including high-temperature reverse bias (HTRB), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST) per AEC-Q101 Rev G.
What is the reverse leakage current of the MBR1090CTH at 90V and 125°C?
The MBR1090CTH exhibits a maximum reverse leakage current (IR) of 2 mA per diode at rated VR = 90V and TJ = 125°C. This value is confirmed in the Electrical Specifications table and is significantly lower than comparable 90V Schottky rectifiers rated for 3–5 mA under identical conditions.
Can the MBR1090CTH be used in parallel configurations?
Yes - the MBR1090CTH's matched dual-die construction and low thermal resistance enable balanced current sharing when paralleled across transformer secondary windings or in multiphase rectifier banks. Ensure symmetrical PCB layout and shared heatsinking to maintain thermal uniformity between anodes.
