Taiwan Semiconductor Corporation MBR6090PT

Overview

MBR6090PT from Taiwan Semiconductor is a 60A, 90V dual-die Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.98V forward voltage at 60A/25°C, 420A surge capability, 1.2°C/W junction-to-case thermal resistance, and AEC-Q101 qualification option. It serves as a high-efficiency output rectifier in high-power SMPS and DC-DC converters for industrial and consumer power systems.

For engineers reviewing the MBR6090PT datasheet, MBR6090PT pinout, MBR6090PT application, or MBR6090PT equivalent, key selection criteria include its 90V V_RRM, dual-die configuration enabling parallel operation without external balancing, low conduction loss at elevated temperature, and UL recognition for safety-critical power supplies.

Technical Context

This device integrates two independent Schottky die in a single TO-247AD package with common cathode connection, supporting high-current, low-V_F rectification in center-tapped or dual-output topologies. Its 10,000 V/μs dV/dt rating and guard ring structure provide robust noise immunity and overvoltage protection during switching transients.

Designed for continuous operation up to 150°C junction temperature, the MBR6090PT delivers stable reverse leakage ≤10 mA at 125°C and maintains <0.98V forward drop under full 60A DC load at room temperature-critical for minimizing conduction losses in high-density power stages.

FAQ

What is the maximum junction temperature rating for the MBR6090PT?

The MBR6090PT has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows continuous operation in high-ambient environments such as enclosed industrial power supplies or telecom rectifier modules. Derating begins above 25°C ambient, and thermal design must ensure the MBR6090PT junction stays within this limit under worst-case load and airflow conditions.

Does the MBR6090PT have AEC-Q101 qualification?

The MBR6090PT itself is not automatically AEC-Q101 qualified; however, the AEC-Q101 qualified version is offered as MBR6090PTH (with 'H' suffix). The 'H' variant undergoes additional stress testing per AEC-Q101 Rev D, including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress test. For automotive applications, specify MBR6090PTH-not MBR6090PT-to ensure compliance.

What is the forward voltage drop of the MBR6090PT at full rated current?

The MBR6090PT exhibits a maximum forward voltage (V_F) of 0.98 V at 60 A and 25°C junction temperature, as specified in the electrical characteristics table. At 125°C, V_F decreases to approximately 0.84 V due to negative temperature coefficient of Schottky diodes-this improves efficiency at elevated temperatures but requires accurate thermal modeling to avoid misinterpretation of conduction loss.

How is the dual-die configuration of the MBR6090PT implemented electrically?

The MBR6090PT contains two independent Schottky dies sharing a common cathode terminal and housed in a single TO-247AD package. Anode 1 and Anode 2 are fully isolated terminals, enabling flexible circuit topologies-including dual-output rectification, interleaved phase operation, or redundancy. No internal connection exists between the anodes; external PCB routing determines functional configuration.

What is the thermal resistance from junction to case for the MBR6090PT?

The junction-to-case thermal resistance (R_θJC) of the MBR6090PT is 1.2°C/W, measured under standard mounting conditions with proper heatsink interface (e.g., thermal grease and 1.13 N·m torque). This value is critical for calculating temperature rise: ΔT = R_θJC × P_loss. For example, at 60 A and 0.98 V drop, power dissipation is 58.8 W, resulting in a 70.6°C rise above case temperature-requiring appropriate heatsinking to maintain T_J ≤ 150°C.
