Infineon IPD60R1K0CE: A 600V CoolMOS™ CE Power Transistor for High-Efficiency Applications

The relentless pursuit of higher efficiency and power density in modern electronic systems demands continuous innovation in power semiconductor technology. At the forefront of this evolution is Infineon Technologies' CoolMOS™ CE series, with the IPD60R1K0CE standing out as a premier 600V superjunction MOSFET engineered to meet these rigorous challenges. This device is specifically tailored for high-performance switched-mode power supplies (SMPS), power factor correction (PFC) stages, and lighting applications where efficiency and reliability are paramount.

A defining characteristic of the IPD60R1K0CE is its exceptionally low on-state resistance (R DS(on)) of just 100 mΩ (max). This crucial parameter is a primary determinant of conduction losses; a lower R DS(on) means less energy is wasted as heat when the transistor is fully switched on. This translates directly into higher overall system efficiency, cooler operation, and the potential for designers to create more compact solutions by reducing the need for large heat sinks.

The technology behind this performance is Infineon's advanced superjunction (SJ) principle. This design breaks the traditional silicon limit, enabling a superior relationship between breakdown voltage and on-resistance. The result is a component that offers minimal switching and conduction losses, even when operating at high frequencies. This high-frequency capability is a key enabler for increasing power density, as it allows for the use of smaller passive components like inductors and transformers.

Furthermore, the IPD60R1K0CE is renowned for its robustness and reliability. It features a very low effective output capacitance (C OSS(eff)) and an integrated fast body diode, which ensures clean and efficient switching while enhancing its resilience against voltage spikes and other stressful conditions commonly encountered in hard-switching topologies. This makes it an exceptionally durable choice for demanding commercial and industrial environments.
