an815 vishay siliconix document number: 71334 12-dec-03 www.vishay.com 1 single-channel little foot sc-70 6-pin mosfet copper leadframe version recommended pad pattern and thermal performance introduction the new single 6-pin sc-70 package with a copper leadframe enables improved on-resistance values and enhanced thermal performance as compared to the existing 3-pin and 6-pin packages with alloy 42 leadframes. these devices are intended for small to medium load applications where a miniaturized package is required. devices in this package come in a range of on-resistance values, in n-channel and p-channel versions. this technical note discusses pin-outs, package outlines, pad patterns, evaluation board layout, and thermal performance for the single-channel version. basic pad patterns see application note 826, recommended minimum pad patterns with outline drawing access for vishay siliconix mosfet s, ( http://www.vishay.com/doc?72286 ) for the basic pad layout and dimensions. these pad patterns are sufficient for the low to medium power applications for which this package is intended. increasing the drain pad pattern yields a reduction in thermal resistance and is a preferred footprint. the availability of four drain leads rather than the traditional single drain lead allows a better thermal path from the package to the pcb and external environment. pin-out figure 1 shows the pin-out description and pin 1 identification.the pin-out of this device allows the use of four pins as drain leads, which helps to reduce on-resistance and junction-to-ambient thermal resistance. figure 1. sot-363 sc-70 (6-leads) 6 4 1 2 3 5 top view d d g d d s for package dimensions see outline drawing sc-70 (6-leads) ( http://www.vishay.com/doc?71154 ) evaluation boards single sc70-6 the evaluation board (evb) measures 0.6 inches by 0.5 inches. the c opper pad traces are the same as in figure 2. the board allows examination from the outer pins to 6-pin dip connections, permitting test sockets to be used in evaluation testing. see figure 3. figure 2. sc-70 (6 leads) single 52 (mil) 96 (mil) 13 (mil) 71 (mil) 0, 0 (mil) 18 (mil) 16 (mil) 26 (mil) 26 (mil) 654 3 2 1 the thermal performance of the single 6-pin sc-70 has been measured on the evb, comparing both the copper and alloy 42 leadframes. this test was first conducted on the traditional alloy 42 leadframe and was then repeated using the 1-inch 2 pcb with dual-side copper coating. www.datasheet.co.kr datasheet pdf - http://www..net/
