Infineon IPD50P04P4L11: High-Performance P-Channel Power MOSFET for Automotive and Industrial Applications

The relentless drive for higher efficiency, robustness, and miniaturization in power electronics has made the choice of switching components more critical than ever. Addressing these demanding requirements, the Infineon IPD50P04P4L11 stands out as a premier P-Channel Power MOSFET engineered to excel in the harsh environments of automotive and industrial systems.

As a P-Channel MOSFET, this device offers a significant advantage in circuit simplification, particularly for high-side switching applications. Its operation allows for direct drive from microcontroller units (MCUs) without the need for additional charge pumps or level shifters, which are often required with N-Channel alternatives. This inherent trait simplifies design, reduces component count, and enhances overall system reliability.

The IPD50P04P4L11 is built on Infineon’s advanced OptiMOS™ technology, a hallmark of performance in power semiconductors. This technology empowers the MOSFET with an exceptionally low typical on-state resistance (RDS(on)) of just 13.5 mΩ at a gate-source voltage of -10 V. This ultra-low RDS(on) is pivotal in minimizing conduction losses, leading to superior efficiency and reduced heat generation. Consequently, designers can achieve higher power density or utilize smaller heatsinks, contributing to more compact and cost-effective end products.

Robustness and reliability are at the core of its design, making it an ideal candidate for the automotive sector. It is qualified according to the stringent AEC-Q101 standard, ensuring it can withstand the temperature extremes, humidity, and constant vibration encountered in vehicles. Typical applications include load switches, motor control modules, and power management units within body control modules, advanced driver-assistance systems (ADAS), and infotainment systems.

In the industrial domain, its capabilities are equally valuable. The device is suited for managing power distribution, controlling actuators, and serving as a solid-state relay in programmable logic controllers (PLCs), robotics, and power supplies. Its ability to handle a continuous drain current (ID) of -50 A and a voltage (VDS) of -40 V provides ample headroom for a wide array of 12V and 24V systems.

Furthermore, the IPD50P04P4L11 features a logic-level gate threshold, enhancing its compatibility with modern low-voltage control ICs. Its high avalanche ruggedness and 100% automated wafer-level testing further guarantee long-term operational stability and quality.

ICGOOODFIND: The Infineon IPD50P04P4L11 is a top-tier P-Channel MOSFET that delivers a potent combination of ultra-low resistance, high current handling, and automotive-grade reliability. It simplifies circuit design, boosts efficiency, and provides the durability needed for the most challenging applications in automotive and industrial electronics.
