This product series has a surge capability of 500 Watts PPP per line for an 8/20µs waveshape and offers ESD protection > 40kv. BIDIRECTIONAL COMMON MODE CONFIGURATION (Figure 1) Ideal for use in USB applications, the PLCDA Series provides up to two (2) lines of protection in a common mode configuration as depicted in Figure 1. Circuit connectivity is as follows: ✔ Pins 1 & 2 and 3 & 4 are connected to Ground. ✔ Pins 5 and 6 are connected to I/O Line D+. ✔ Pins 7 and 8 are connected to I/O Line D-. CIRCUIT BOARD LAYOUT RECOMMENDATIONS Circuit board layout is critical for Electromagnetic Compatibility (EMC) protection. The following guidelines are recommended: ✔ ✔ 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. USB IC D- 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. ✔ ✔ D+ 8 7 6 5 1 2 3 4 GND Figure 1. Typical Common-Mode USB Protection Circuit Ground planes should be used whenever possible. For multilayer PCBs, use ground vias. 05076.R5 1/02 4 www.protekdevices.com PLCDA03 thru PLCDA24 PACKAGE OUTLINE & DIMENSIONS PACKAGE OUTLINE SO-8 -A- 8 5 -B- 0.010” (0.25 MM) P M B M 4 PL 1 PACKAGE DIMENSIONS 4 DIM D G C R X 45º 0º - 10º -TJ K 0.010” (0.25 MM) M T B S F A S 8 PL MOUNTING PAD 4.80 3.80 1.35 0.35 0.40 1.27 BSC 0.18 0.10 5.80 0.25 INCHES MIN MAX 5.00 0.189 0.196 4.00 0.150 0.157 1.75 0.054 0.068 0.49 0.014 0.019 1.250 0.016 0.049 1.27 BSC 0.05 BSC 0.05 BSC 0.25 0.007 0.009 0.25 0.004 0.008 6.20 0.229 0.244 0.50 0.010 0.019 NOTES: 1. - T - = Seating Plane and Datum Surface. 2.
