Infineon F4-50R12KS4 | High-Efficiency 1200V Four-Pack IGBT Module
The Infineon F4-50R12KS4 is a 1200V, 50A IGBT module engineered for demanding power conversion applications. Housed in the industry-standard EconoPIM™ 2 package, this module integrates a full H-bridge (four-pack) configuration, leveraging Infineon's advanced IGBT4 technology to deliver a superior balance of efficiency, reliability, and power density. It is an ideal solution for compact and high-performance motor drives, solar inverters, and uninterruptible power supplies (UPS).
Technical Deep Dive: Unpacking the F4-50R12KS4's Core Advantages
- IGBT4 Trench Field-Stop Technology: At the heart of the F4-50R12KS4 lies Infineon’s mature IGBT4 Trench Field-Stop technology. This design optimizes the trade-off between collector-emitter saturation voltage (Vce(sat)) and switching losses. The result is significantly lower on-state power dissipation, which directly translates to reduced heat generation and higher overall system efficiency. Furthermore, its "soft" switching behavior minimizes voltage overshoots and electromagnetic interference (EMI), simplifying the design of snubber circuits and filtering components.
- Integrated H-Bridge (Four-Pack) Topology: Unlike standard six-pack modules, the F4-50R12KS4 provides a complete H-bridge configuration in a single package. This topology is purpose-built for applications requiring bidirectional current control, such as four-quadrant DC motor controllers and single-phase inverters. This integration simplifies PCB layout, reduces stray inductance, and lowers assembly costs by minimizing the number of discrete components on the board.
Application Scenarios and Value Proposition
The unique features of the Infineon F4-50R12KS4 translate into tangible benefits across several key industrial applications:
- Solar Inverters & UPS Systems: In grid-tied solar inverters and online UPS systems, efficiency is paramount. The low Vce(sat) of the F4-50R12KS4 minimizes conduction losses during power conversion, maximizing energy harvest and reducing operational costs. The integrated H-bridge simplifies the design of the main inverter stage, contributing to a more compact and cost-effective final product.
- DC Motor Drives and Servo Control: The module’s H-bridge topology is perfectly suited for DC chopper and servo drive applications. It allows for precise four-quadrant control, enabling both motoring and regenerative braking. This enhances system responsiveness and energy efficiency, which is critical in robotics and industrial automation.
- Welding Equipment: High-frequency welding power sources demand robust and fast-switching components. The F4-50R12KS4 delivers the necessary switching performance and thermal stability to handle the pulsed high-current loads typical in welding, ensuring consistent weld quality and long-term equipment reliability.

Selection Guidance: F4-50R12KS4 (Four-Pack) vs. Standard Six-Pack Modules
Engineers often decide between different module topologies. While a 6-pack IGBT module is the standard choice for three-phase inverters, the F4-50R12KS4 offers a distinct advantage for other applications. Choose the F4-50R12KS4 if your design involves single-phase inverters, full-bridge DC-DC converters, or DC motor choppers. Its integrated H-bridge will streamline your design. For three-phase motor drives or grid-tied inverters, a six-pack module would be the more appropriate choice. If you need assistance with selection, feel free to contact our technical team.
Frequently Asked Questions (FAQ)
- What is the primary benefit of the integrated NTC thermistor?The built-in NTC thermistor provides real-time temperature feedback directly from the module's substrate. This allows for precise thermal monitoring and enables protective features like over-temperature shutdown, significantly enhancing the reliability and lifespan of the power system.
- Can the F4-50R12KS4 be used for applications requiring paralleling?Yes, the positive temperature coefficient of the Vce(sat) in the IGBT4 technology makes it well-suited for paralleling. However, careful PCB layout to ensure symmetrical current sharing and gate drive signal integrity is crucial for reliable operation.
