Infineon IPD350N06LGBTMA1: High-Performance OptiMOS 5 Power Transistor for Automotive Applications

The relentless drive towards vehicle electrification, from advanced powertrains to sophisticated ADAS, demands power semiconductors that deliver uncompromising efficiency, reliability, and power density. Addressing these core requirements, the Infineon IPD350N06LGBTMA1 stands out as a premier OptiMOS™ 5 power MOSFET engineered specifically for the rigorous demands of the automotive industry.

This transistor is built upon Infineon’s advanced OptiMOS™ 5 technology platform, which represents a significant leap in performance over previous generations. Housed in a robust PG-TDSON-8 (5x6) package, the device is characterized by an ultra-low on-state resistance (RDS(on)) of just 3.5 mΩ maximum. This exceptionally low resistance is pivotal in minimizing conduction losses, which directly translates to higher system efficiency and reduced heat generation. For automotive designers, this means the ability to handle high currents with greater ease, leading to more compact thermal management solutions and ultimately, smaller and lighter electronic control units (ECUs).

A key hallmark of the IPD350N06LGBTMA1 is its AEC-Q101 qualification, guaranteeing its reliability and performance under the extreme conditions typical of automotive environments. It is designed to operate flawlessly across a wide temperature range, ensuring stability whether in a blistering engine compartment or a freezing cold start scenario. This makes it an ideal solution for a vast array of applications, including:

Electric Power Steering (EPS) systems

Brushed and Brushless DC motor drives

Body control modules (e.g., seat controllers, window lifters)

Battery management systems (BMS) and 12V/48V DC-DC converters

Furthermore, the device offers enhanced switching performance, which helps to lower switching losses in high-frequency circuits. This is crucial for increasing the power density of inverters and converters, allowing them to achieve higher operating frequencies without a penalty in efficiency. The combination of low RDS(on) and fast switching speed ensures that systems can operate cooler and more reliably, extending their operational lifespan.

The PG-TDSON-8 package also provides excellent thermal performance due to its exposed drain pad, which allows for efficient heat dissipation directly from the die to the PCB. This robust construction, coupled with its high current capability, ensures the transistor can withstand the electrical and mechanical stresses encountered in automotive applications.
