Power MOSFETs halve mounting area

Renesas Electronics Corp. launches 32 N-channel power MOSFETs including the NP75N04YUK device featuring a compact HSON package with one-half the mounting area of the existing TO-252 package and the capability to handle current flows up to 75A.

The MOSFETs feature voltage tolerances of 40V and 55V. They use Renesas' ANL2 fabrication process that minimises on-resistance and offers improved high-speed switching performance.

Compared to the conventional UMOS4 process, the ANL2 process offers approximately 40 per cent improvements on the Figure of Merit (FOM) with a performance index equivalent to the device on-resistance multiplied by the gate charge.

The NP75N04YUK device combines the advanced ANL2 technology with the compact HSON-8 package (external dimensions: 6mm × 5.15mm) that is approximately one-half the size of the existing TO-252 package while offering heat dispersion characteristics. These advancements enable the NP75N04YUK device to drive up to 75A and to achieve an on-resistance of 3.3mΩ. Using the power MOSFETs, Renesas says, will enable customers to build automotive control units that are more compact and higher in performance.

The line-up of MOSFETs ranges from products rated to handle 180A, targeting 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 7-pin, TO-263, TO-252, HSON, THD, TO-220 and TO-262). Also, voltage tolerance ratings of 40 and 55V are available to accommodate a wide range of customer requirements.

Samples of the power MOSFETs are available now. The NP75N04YUK device is priced at Rs.59.63 ($1.30) each in quantities of 1,000 pieces. Mass production is scheduled to begin in April 2011 and is expected to reach a combined volume of 20,00,000 units per month in 2012 for 14 of the new products equipped in an HSON package.
