Taiwan Semiconductor Corporation MBR6050PTH

Overview

MBR6050PTH from Taiwan Semiconductor is a 60A, 50V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD package, featuring dual-die construction, 420A surge capability, 1.2°C/W junction-to-case thermal resistance, and 0.93V forward voltage at 60A/25°C. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters.

For engineers reviewing the MBR6050PTH datasheet, MBR6050PTH pinout, MBR6050PTH application, or MBR6050PTH equivalent, key selection criteria include its 50V V_RRM, AEC-Q101 qualification, TO-247AD mechanical compatibility, 20mA reverse leakage at 125°C, and suitability for high-current switching power supplies requiring low conduction loss.

Technical Context

This device implements a dual-die parallel configuration within a single TO-247AD package to achieve 60A average forward current while maintaining low thermal resistance (1.2°C/W). Its Schottky architecture enables zero minority-carrier storage, supporting high-frequency operation up to 20kHz square-wave rating.

The MBR6050PTH is rated for 50V repetitive peak reverse voltage (V_RRM) and 35V RMS reverse voltage, with 10,000 V/μs critical dV/dt rating and 150°C maximum junction temperature - enabling robust operation in automotive transients and industrial power cycling.

FAQ

What is the maximum junction temperature rating for the MBR6050PTH?

The MBR6050PTH has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. Thermal design must ensure that actual junction temperature remains below this limit under worst-case load and ambient conditions, using the specified 1.2°C/W R_θJC value and appropriate heatsinking. The MBR6050PTH datasheet confirms this rating applies across its full operating voltage range.

Is the MBR6050PTH pin-compatible with other parts in the MBR60xPT family?

Yes, the MBR6050PTH shares identical TO-247AD package dimensions, pinout, and terminal configuration with all MBR60xPT and MBR60xPTH variants (e.g., MBR6035PTH, MBR60100PTH). All devices feature dual-anode/single-cathode layout with electrically isolated tab. Voltage rating differences (35V–100V) do not affect mechanical or electrical interface compatibility, enabling drop-in replacement during design iteration or voltage-scaling upgrades - provided reverse voltage stress remains within the selected part's V_RRM.

Does the MBR6050PTH require a thermal pad or insulator when mounted to a heatsink?

Yes - the MBR6050PTH uses an electrically isolated tab (TO-247AD package), meaning the metal case is not internally connected to any terminal. While isolation eliminates mandatory electrical insulation, a thermally conductive but electrically insulating pad (e.g., silicone-based thermal interface material) is strongly recommended to maximize heat transfer from the tab to the heatsink. Mounting without such a pad risks elevated junction temperatures due to interfacial air gaps, especially under sustained 60A load. The MBR6050PTH datasheet specifies 1.13 N·m maximum torque to avoid cracking the molding compound.

What is the reverse leakage current specification for the MBR6050PTH at elevated temperature?

The MBR6050PTH specifies 20 mA maximum reverse leakage current (I_R) at rated 50V reverse voltage and 125°C junction temperature. At 25°C and 50V, leakage is limited to 1000 µA. This temperature-dependent behavior is critical for standby power budgeting and thermal runaway analysis in parallel configurations. The MBR6050PTH datasheet confirms these values are measured per JEDEC-standard pulse conditions (30ms PW), and the device's guard ring structure helps stabilize leakage under voltage stress.

How does the dual-die configuration of the MBR6050PTH improve reliability compared to single-die alternatives?

The MBR6050PTH integrates two matched Schottky dies in parallel within one TO-247AD package, distributing current and thermal load across both elements. This reduces localized heating, lowers effective forward voltage drift over time, and increases tolerance to single-die defects or electromigration. In practice, dual-die architecture extends lifetime in high-temperature, high-current applications like automotive DC-DC converters - where the MBR6050PTH's AEC-Q101 qualification validates its robustness beyond single-die counterparts. The MBR6050PTH's 420A I_FSM rating further reflects this redundancy.
