Infineon IKD04N60R: A 600V, 4A High-Speed Switching N-Channel Power MOSFET

In the realm of power electronics, efficiency, reliability, and switching performance are paramount. The Infineon IKD04N60R stands out as a robust N-Channel power MOSFET engineered to meet these demanding criteria. Designed with advanced technology, this component is a cornerstone for high-efficiency switching power supplies, motor control, and industrial applications.

At its core, the IKD04N60R is characterized by its high-voltage capability of 600V and a continuous drain current rating of 4A. This makes it exceptionally suitable for off-line switch-mode power supplies (SMPS) and other circuits operating from high-voltage rails. A key highlight of this MOSFET is its exceptionally low gate charge (Qg) and low output capacitance (Coss), which are critical parameters for achieving high-speed switching. The reduced switching losses directly translate into higher overall system efficiency, allowing designers to push the boundaries of power density and thermal performance.

The device leverages Infineon’s proven trench cell technology, which minimizes on-state resistance. The low RDS(on) of 1.8Ω ensures minimal conduction losses when the transistor is fully switched on, further enhancing efficiency and reducing heat generation. This combination of low gate charge and low on-resistance is a hallmark of a superior switching device, enabling it to operate effectively at high frequencies.

Another significant advantage is its fast and soft body diode, which improves reverse recovery characteristics. This feature is vital in circuits like power factor correction (PFC) or half-bridge configurations, where the body diode's behavior can significantly impact electromagnetic interference (EMI) and overall switching noise.

The IKD04N60R is offered in the industry-standard TO-252 (DPAK) package, providing a good balance between compact size and excellent thermal performance. Its high ruggedness and avalanche energy capability ensure reliable operation even under stressful conditions like voltage spikes or inductive load switching.

ICGOOODFIND: The Infineon IKD04N60R is a highly efficient and reliable high-speed switching MOSFET. Its optimal blend of low gate charge, low on-resistance, and a robust 600V rating makes it an outstanding choice for designers aiming to maximize performance in AC-DC converters, motor drives, and lighting ballasts.
