Taiwan Semiconductor Corporation MBR3090PTH

Overview

MBR3090PTH from Taiwan Semiconductor is a 30A, 90V AEC-Q101 qualified Schottky barrier rectifier in TO-247AD package, featuring 0.85V forward voltage at 15A/25°C, 10mA reverse current at 125°C, and 200A surge capability - deployed in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBR3090PTH datasheet, MBR3090PTH pinout, MBR3090PTH application, or MBR3090PTH equivalent, key selection criteria include its 90V V_RRM, dual-die construction, 1.4°C/W junction-to-case thermal resistance, AEC-Q101 qualification, and TO-247AD mechanical compatibility with high-power heatsink mounting.

Technical Context

This device implements a dual-die Schottky architecture optimized for low conduction loss in high-frequency switching topologies. Its 90V repetitive peak reverse voltage and 200A non-repetitive surge rating support robust operation under transient overloads in automotive power rails.

The 1.4°C/W R_θJC enables efficient thermal transfer to heatsinks, while the guard ring structure provides intrinsic overvoltage protection. It operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance.

FAQ

What is the maximum junction temperature rating for MBR3090PTH?

The MBR3090PTH has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define safe operating current versus case temperature, with full 30A rated up to 100°C case temperature. The MBR3090PTH maintains stable electrical parameters across its full –55°C to +150°C junction range.

Is MBR3090PTH pin-compatible with MBR3090PT?

Yes, the MBR3090PTH shares identical TO-247AD package dimensions, pinout, and thermal pad configuration with MBR3090PT. The only difference is AEC-Q101 qualification - the "H" suffix denotes enhanced reliability testing per automotive stress standards. No PCB layout changes are needed when upgrading from MBR3090PT to MBR3090PTH in existing designs requiring automotive qualification.

What is the forward voltage specification for MBR3090PTH at elevated temperature?

At 30A and 125°C junction temperature, the MBR3090PTH exhibits a typical forward voltage of 0.92V (max not specified). At 15A and 125°C, it is 0.75V (typical). These values reflect stable Schottky behavior with minimal V_F increase over temperature - critical for maintaining efficiency in thermally constrained applications. The MBR3090PTH datasheet confirms these points in its Electrical Specifications table under TJ = 125°C conditions.

Does MBR3090PTH have a guard ring structure, and what does it do?

Yes, the MBR3090PTH incorporates a guard ring structure explicitly documented in its features list. This design prevents premature avalanche breakdown at the silicon periphery under high dv/dt stress, enabling reliable operation at rated 10,000 V/μs critical rate of rise. The guard ring enhances ruggedness in fast-switching circuits like LLC resonant converters and motor drives where voltage transients exceed 500V/μs. This feature is integral to the MBR3090PTH's AEC-Q101 qualification.

What packaging and plating specifications apply to MBR3090PTH leads?

The MBR3090PTH uses matte tin-plated leads compliant with J-STD-002 for solderability, and passes JESD201 Class 2 whisker testing. Its TO-247AD molding compound meets UL 94V-0 flammability rating. The device is supplied in tubes (30 per tube), with "H" suffix confirming AEC-Q101 qualification. Mounting torque must not exceed 1.13 N·m to avoid package damage. Polarity is marked on the device body per standard orientation.
