These new Vishay Siliconix devices are intended for small-signal applications where a miniaturized package is needed and low levels of current (around 350 mA) need to be switched, either directly or by using a level shift configuration. Vishay provides these single devices with a range of on-resistance specifications and in both traditional 3-pin and new 6-pin versions. The new 6-pin SC-70 package enables improved on-resistance values and enhanced thermal performance compared to the 3-pin package. See Application Note 826, Recommended Minimum Pad Patterns With Outline Drawing Access for Vishay Siliconix MOSFETs, (http://www.vishay.com/doc?72286) for the basic pad layout and dimensions for the 3-pin SC-70 and the 6-pin SC-70. These pad patterns are sufficient for the low-power applications for which this package is intended. Increasing the pad pattern has little effect on thermal resistance for the 3-pin device, reducing it by only 10% to 15%. But for the 6-pin device, increasing the pad patterns yields a reduction in thermal resistance on the order of 35% when using a 1-inch square with full copper on both sides of the printed circuit board (PCB). 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 for the single-channel SC-70 device in both 3-pin and 6-pin configurations. The pin-out of the 6-pin device allows the use of four pins as drain leads, which helps to reduce on-resistance and junction-to-ambient thermal resistance.

Both measure 0.6 inches by 0.5 inches. Their copper pad traces are the same as described in the previous section, Basic Pad Patterns. Both boards allow interrogation from the outer pins to 6-pin DIP connections, permitting test sockets to be used in evaluation testing. The thermal performance of the single SC-70 has been measured on the EVB for both the 3-pin and 6-pin devices, the results shown in Figures 3 and 4. The minimum recommended footprint on the evaluation board was compared with the industry standard of 1-inch square FR4 PCB with copper on both sides of the board. FIGURE 1.

Document Number: 71236 12-Dec-03 www.vishay.com 1 AN813 Vishay Siliconix THERMAL PERFORMANCE Junction-to-Foot Thermal Resistance (the Package Performance) SC-70 (6-PIN) Thermal performance for the 3-pin SC-70 measured as junction-to-foot thermal resistance is 285_C/W typical, 340_C/W maximum. Junction-to-foot thermal resistance for the 6-pin SC70-6 is 105_C/W typical, 130_C/W maximum — a nearly two-thirds reduction compared with the 3-pin device. The “foot” is the drain lead of the device as it connects with the body. This improved performance is obtained by the increase in drain leads from one to four on the 6-pin SC-70. Note that these numbers are somewhat higher than other LITTLE FOOT devices due to the limited thermal performance of the Alloy 42 lead-frame compared with a standard copper lead-frame. The typical RθJAfor the single 3-pin SC-70 is 360_C/W steady state, compared with 180_C/W for the 6-pin SC-70. Maximum ratings are 430_C/W for the 3-pin device versus 220_C/W for the 6-pin device. All figures are based on the 1-inch square FR4 test board.The following table shows how the thermal resistance impacts power dissipation for the two different pin-outs at two different ambient temperatures.

The results display the thermal performance out to steady state and produce a graphic account of the thermal performance variation between the two packages. The measured steady state values of RθJA for the single 3-pin and 6-pin SC-70 are as follows: LITTLE FOOT SC-70 Thermal Resistance (C/W) 320 3-pin 6-pin 160 80 329.7_C/W 360_C/W 211.8_C/W 3-pin 6-pin 160 80 1” Square FR4 PCB 0 10-3 10-2 10-1 1 10 100 1000 10-5 10-4 Comparison of SC70-3 and SC70-6 on EVB 10-3 10-2 10-1 1 10 100 1000 Time (Secs) Time (Secs) 2 410.31_C/W 240 0.5 in x 0.6 in EVB 0 www.vishay.com 6-Pin The results show that designers can reduce thermal resistance RθJA on the order of 20% simply by using the 6-pin device rather than the 3-pin device. In this example, a 80_C/W reduction was achieved without an increase in board area. If increasing board size is an option, a further 118_C/W reduction could be obtained by utilizing a 1-inch square PCB area. 320 240 3-Pin 2) Industry standard 1” square PCB with maximum copper both sides. 400 FIGURE 3.
