Renesas Electronics has introduced 32 N-channel power metal-oxide-semiconductor field-effect transistors with voltage tolerances of 40 and 55V. The power MOSFETs include the NP75N04YUK device, featuring a compact HSON package with one-half the mounting area of the existing TO-252 package and the ability to handle current flows of up to 75A. All of the 32 new power MOSFETs employ the company's ANL2 fabrication process that minimises on-resistance and provides improved high-speed switching performance. Compared to the conventional UMOS4 process, the ANL2 process provides approximately 40% improvement on the Figure of Merit performance index equivalent to the device on-resistance multiplied by the gate charge. The MOSFET combines the ANL2 technology with the compact HSON-8 package that is approximately one-half the size of the existing TO-252 package. These advancements enable the device to drive up to 75A and to achieve an on-resistance of 3.3mOhms. The ANL2 fabrication process is optimised to provide a balance between on-resistance and low gate charge. The on-resistance and gate charge are indirectly related to each other, and the product obtained by multiplying the two values is used as an index of process performance. Four of the power MOSFETs feature the HSON package (external dimensions: 6×5.15mm), and providesenhanced heat dispersion characteristics. These advances enable the NP75N04YUK device, a power MOSFET with a voltage tolerance of 40V, to achieve low on-resistance. The lineup ranges from products rated to handle 180A, suitable for large-current applications such as electric power steering, to products in the 35A class, suitable for driving compact solenoids, and includes packages for a variety of mounting configurations (SMD, TO-263 7pin, TO-263, TO-252, HSON, THD, TO-220 and TO-262). In addition, voltage tolerance ratings of 40 and 55V are available to accommodate a range of customer requirements. The products are suitable for configuring compact and high-performance control systems for automotive applications.
