The 1206-8 ChipFET has the same footprint as the body of the LITTLE FOOTR TSOP-6, and can be thought of as a leadless TSOP-6 for purposes of visualizing board area, but its thermal performance bears comparison with the much larger SO-8. This technical note discusses the dual ChipFET 1206-8 pin-out, package outline, pad patterns, evaluation board layout, and thermal performance. 80 mil 25 mil 43 mil 18 mil 10 mil 26 mil PIN-OUT FIGURE 2. Figure 1 shows the pin-out description and Pin 1 identification for the dual-channel 1206-8 ChipFET device. The pin-out is similar to the TSOP-6 configuration, with two additional drain pins to enhance power dissipation and thus thermal performance. The legs of the device are very short, again helping to reduce the thermal path to the external heatsink/pcb and allowing a larger die to be fitted in the device if necessary. Dual 1206-8 ChipFET S1 G1 S2 Footprint With Copper Spreading The pad pattern with copper spreading shown in Figure 2 improves the thermal area of the drain connections (pins 5 and 6, pins 7 and 8) while remaining within the confines of the basic footprint. The drain copper area is 0.0019 sq. in. or 1.22 sq. mm. This will assist the power dissipation path away from the device (through the copper leadframe) and into the board and exterior chassis (if applicable) for the dual device. The addition of a further copper area and/or the addition of vias to other board layers will enhance the performance still further. An example of this method is implemented on the Vishay Siliconix Evaluation Board described in the next section (Figure 3). G2 D1 THE VISHAY SILICONIX EVALUATION BOARD FOR THE DUAL 1206-8 D1 D2 D2 FIGURE 1. For package dimensions see the 1206-8 ChipFET package outline drawing (http://www.vishay.com/doc?71151). BASIC PAD PATTERNS The basic pad layout with dimensions is shown in Application Note 826, Recommended Minimum Pad Patterns With Outline Drawing Access for Vishay Siliconix MOSFETs, (http://www.vishay.com/doc?72286). This is sufficient for low power dissipation MOSFET applications, but power semiconductor performance requires a greater copper pad area, particularly for the drain leads. Document Number: 71127 12-Dec-03 The dual ChipFET 1206-08 evaluation board measures 0.6 in by 0.5 in. Its copper pad pattern consists of an increased pad area around each of the two drain leads on the top-side— approximately 0.0246 sq. in. or 15.87 sq. mm—and vias added through to the underside of the board, again with a maximized copper pad area of approximately the board-size dimensions, split into two for each of the drains. The outer package outline is for the 8-pin DIP, which will allow test sockets to be used to assist in testing. The thermal performance of the 1206-8 on this board has been measured with the results following on the next page. The testing included comparison with the minimum recommended footprint on the evaluation board-size pcb and the industry standard one-inch square FR4 pcb with copper on both sides of the board. www.vishay.com 1 AN812 Vishay Siliconix Front of Board Back of Board ChipFETr vishay.com FIGURE 3. Junction-to-Foot Thermal Resistance (the Package Performance) Thermal performance for the 1206-8 ChipFET measured as junction-to-foot thermal resistance is 30_C/W typical, 40_C/W maximum for the dual device. The “foot” is the drain lead of the device as it connects with the body. This is identical to the dual SO-8 package RQjf performance, a feat made possible by shortening the leads to the point where they become only a small part of the total footprint area. Junction-to-Ambient Thermal Resistance (dependent on pcb size) The typical RQja for the dual-channel 1206-8 ChipFET is 90_C/W steady state, identical to the SO-8. Maximum ratings are 110_C/W for both the 1206-8 and the SO-8. Both packages have comparable thermal performance on the 1” square pcb footprint with the 1206-8 dual package having a quarter of the body area, a significant factor when considering board area. The results show that a major reduction can be made in the thermal resistance by increasing the copper drain area. In this example, a 57_C/W reduction was achieved without having to increase the size of the board. If increasing board size is an option, a further 38_C/W reduction was obtained by maximizing the copper from the drain on the larger 1” square PCB. 200 Min.

The measured steady state values of RQja for the Dual 1206-8 ChipFET are : 1) Minimum recommended pad pattern (see Figure 2) on the evaluation board size of 0.5 in x 0.6 in. 185_C/W 2) The evaluation board with the pad pattern described on Figure 3. 128_C/W 3) Industry standard 1” square pcb with maximum copper both sides. 90_C/W www.vishay.com 2 0 10-5 10-4 10-3 10-2 10-1 1 10 100 1000 Time (Secs) FIGURE 4. Dual 1206-8 ChipFET SUMMARY The thermal results for the dual-channel 1206-8 ChipFET package display identical power dissipation performance to the SO-8 with a footprint reduction of 80%. Careful design of the package has allowed for this performance to be achieved. The short leads allow the die size to be maximized and thermal resistance to be reduced within the confines of the TSOP-6 body size.
