Overview
MBR2090PTH from Taiwan Semiconductor is a 20A, 90V AEC-Q101 qualified Schottky barrier rectifier in TO-247AD package, featuring 0.85V forward voltage at 10A/25°C, 150A surge current capability, and junction-to-case thermal resistance of 1°C/W. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters.
For engineers reviewing the MBR2090PTH datasheet, MBR2090PTH pinout, MBR2090PTH application, or MBR2090PTH equivalent, key selection criteria include repetitive peak reverse voltage (90V), forward voltage at 20A/125°C (0.85V), surge current rating (150A), thermal resistance (1°C/W), and AEC-Q101 qualification status.
Technical Context
This device uses dual-die construction in a single TO-247AD package to achieve 20A average forward current with low conduction loss. Its guard ring structure provides overvoltage protection, and it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
The MBR2090PTH operates across -55°C to +150°C junction temperature range, supports 10,000 V/μs critical dV/dt rating, and exhibits 5mA maximum reverse leakage at 90V and 125°C - enabling stable performance in high-temperature automotive power stages.

FAQ
What is the maximum junction temperature rating for MBR2090PTH?
The MBR2090PTH has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from -55°C to +150°C. This rating is confirmed in the Absolute Maximum Ratings table and supports deployment in automotive under-hood environments where ambient temperatures exceed 105°C. The device's 1°C/W junction-to-case thermal resistance enables reliable operation at rated 20A current when properly heatsinked.
Does MBR2090PTH have AEC-Q101 qualification?
Yes, MBR2090PTH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the official datasheet. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - ensuring suitability for automotive power modules including engine control units and ADAS subsystems.
What is the forward voltage specification for MBR2090PTH at full load and elevated temperature?
At 20A forward current and 125°C junction temperature, the MBR2090PTH has a maximum forward voltage (VF) of 0.85V. This value is specified in the ELECTRICAL SPECIFICATIONS table under "IF = 20A, TJ = 125°C" for the MBR2090PT family. The low VF at high temperature directly reduces conduction losses and improves thermal stability in continuous-duty applications.
How does the dual-die configuration of MBR2090PTH affect circuit layout?
The MBR2090PTH integrates two Schottky dies sharing a common cathode in a single TO-247AD package. This eliminates external parallel diode routing, reduces PCB trace inductance, and ensures matched thermal and electrical characteristics between dies. Layout benefits include simplified high-current paths, reduced EMI from circulating currents, and elimination of mismatch-related current imbalance issues seen in discrete dual-diode implementations.
What packaging and plating specifications apply to MBR2090PTH terminals?
MBR2090PTH features matte tin-plated leads compliant with J-STD-002 for solderability, meets JESD201 Class 2 whisker resistance, and uses UL 94V-0 rated molding compound. The TO-247AD case is electrically isolated, and the recommended maximum mounting torque is 1.13 N·m. These specifications ensure robust assembly yield and long-term interconnect reliability in automated SMT/reflow and through-hole manufacturing processes.
