Taiwan Semiconductor Corporation MBR6045PTH

Overview

MBR6045PTH from Taiwan Semiconductor is a 60A, 45V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.70 V forward voltage at 30A/25°C, 420A surge capability, and 1.2 °C/W junction-to-case thermal resistance for high-efficiency DC–DC conversion and SMPS applications.

For engineers reviewing the MBR6045PTH datasheet, MBR6045PTH pinout, MBR6045PTH application, or MBR6045PTH equivalent, this device supports automotive-grade power supplies requiring low conduction loss, robust overvoltage protection via guard ring, and reliable operation up to 150°C junction temperature.

Technical Context

This dual-die Schottky rectifier operates with unidirectional conduction and zero minority-carrier storage, enabling fast switching with no reverse recovery charge. Its 10,000 V/μs critical dV/dt rating ensures stability under rapid voltage transients in high-frequency converters.

The device integrates a guard ring structure for enhanced avalanche ruggedness and meets UL 94V-0 flammability requirements in its molding compound. Matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance standards.

FAQ

What is the maximum junction temperature rating for MBR6045PTH?

The MBR6045PTH has a maximum junction temperature (TJ max) of +150°C, validated across its full operating range from –55°C to +150°C. This rating enables deployment in under-hood automotive environments and high-ambient industrial enclosures. The device maintains specified electrical performance-including forward voltage and leakage current-up to this limit, provided thermal design respects the 1.2°C/W RθJC value and case temperature remains within bounds.

Is MBR6045PTH pin-compatible with MBR6045PT?

Yes, MBR6045PTH shares identical TO-247AD (TO-3P) mechanical dimensions, pinout, and terminal configuration with MBR6045PT. The "H" suffix denotes AEC-Q101 qualification but does not alter physical layout or electrical pin functions. Both parts use Anode 1, Anode 2, and Common Cathode terminals with the same spacing, lead form, and mounting interface-enabling drop-in replacement where automotive qualification is required.

What does the "H" suffix mean in MBR6045PTH?

The "H" suffix in MBR6045PTH indicates full AEC-Q101 qualification per Rev D, including stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock. Unlike standard MBR6045PT, the MBR6045PTH undergoes additional screening and lot-level validation to meet automotive reliability requirements-making it suitable for safety-critical power systems in vehicles without requiring requalification by end customers.

Does MBR6045PTH have a guard ring structure?

Yes, the MBR6045PTH incorporates an integrated guard ring structure around each Schottky junction, explicitly documented in the datasheet features section. This design enhances edge termination robustness, improving resistance to localized avalanche breakdown during transient overvoltage events-particularly beneficial in unregulated input stages of DC–DC converters and flyback SMPS where voltage spikes exceed nominal ratings.

What is the forward voltage specification for MBR6045PTH at 60A and 25°C?

The MBR6045PTH exhibits a maximum forward voltage (VF) of 0.82 V at IF = 60A and TJ = 25°C, as specified in the Electrical Specifications table. This value reflects worst-case conduction loss per diode under full-rated DC current and room-temperature conditions, enabling accurate thermal modeling and efficiency calculation in high-current power supply designs.
