Each, a bidirectional device, can be used on the data lines with signals that are ac in nature. i.e. their amplitude being positive and negative with respect to ground. The standoff voltage (VWM) and breakdown voltage (BVR) specifications apply to the Differential voltage applied across any two pins. Taking the SMDA24CM as an example for further discussion, it being a 24V rated device it can handle ±12V between any two lines. The SMDA24CM is connected as follows: • Pins 1,3,4,5,6,7,8 are connected to the lines that need protection. • Pin 2 is connected to ground. (Any one pin from Pins 2,3,6 and 7 can be chosen to be the ground pin. They provide shorter path to the current within the chip.) During PCB design ensure that the Ground connection made to Pin 2 is directly to the ground plane to avoid needless parasitic inductance that can be introduced by longer PCB traces. circuit board recommendations Circuit board layout is critical for electromagnetic compatibility protection. The following guidelines are recommended: • The protection device should be placed near the input terminals or connectors, the device will divert the transient current immediately before it can be coupled into the nearby traces. • The path length between the TVS device and the protected line should be minimized. • All conductive loops including power and ground loops should be minimized. • The transient current return path to ground should be kept as short as possible to reduce parasitic inductance. • Ground planes should be used whenever possible. For multilayer PCBs, use ground vias. 05070.R9 9/13 Page 4 www.protekdevices.com 05070 SMDA05CM - SMDA24CM Only One Name Means ProTek’Tion™ SO-8 package information outline dimensions dim millimeters -A- inches min max min max A 4.80 5.00 0.189 0.196 B 3.80 4.00 0.150 0.157 C 1.35 1.75 0.054 0.068 D 0.35 0.49 0.014 0.019 F 0.40 1.25 0.016 0.049 G 1.27 BSC 8 5 -B- 1 G 4 D 0.18 0.25 0.007 0.009 K 0.10 0.25 0.004 0.008 P 5.80 6.20 0.229 0.244 R 0.25 0.50 0.010 0.019 R x 45° C 0.05 BSC J + 0.010” (0.25mm) M B M 4 PL P 0° - 10° -T- K + 0.010” (0.25mm) M T B S A S 8 PL J F NOTES 1. 2. 3. 4. 5. 6. -T- = Seating plane and datum surface.
