>> Application background: 1 Global warming, the thunderstorm weather increased 2.DVR is usually placed in the outdoor and easy to be struck by lightning 3. DVR data is lost, the loss is serious. 4 High surge protection of security equipment become a trend >> Program description and notes: 1 This program uses one TSS, it connect the signal line to the ground plane. 2 R2 in the backend of the circuit is used as the decoupling and the current limiting resistor, the resistor recommended as 0805/1206, and the resistance range 0ohm-20ohm, the specific resistance is depended by image quality of the video 3 this TSS junction capacitance is low, does not affect the data transmission; 4 meet IEC61000-4-5, GBT17626.5 and other surge standards, the maximum can withstand 10/700uS(40ohm) 6.0KV , the specific protection level is depended by TSS type choosing. >>Application: 1 Bullet Network Camera 2 Dome Network Camera 3 Set Top Box 5 Digital Satellite Receiver 6 Other devices with video ports >> Protection circuit diagram:
