 14 Aug 2008 1:44 How to deal with ESD? |
|
|
|
I want to design a device with a MCU ,Keyboard and LCD.As the Keyboard is used by hand pushing, the ESD problem is to be thought. As we know the electrostatic may be 10KV of human body,but the optocoupler usually provide a 2KV isolation.
Is there a good idea for this problem?
Thank u for any help

| Actually, each semicon devices is tested with esd zapper up to 15KV. The human body model of ESD is 2KV. The really really actual reality is, no body cares about esd that much unless the instrument that he build is esd sensitive.

hi
the esd actually comes int o picture if u r designing the ESD sensitive device.. and the level of ESD is defined the type of device (+- 2kv, 4KV etc)
coming to the isolation...the isolation doesnot actually mention the ESD sensitivity of the IC, most IC are tested for ESD sensitive whihc they mention in the data sheet

| if you are worried about esd use Trasient Voltage Suppressors on the pins of interest (based on their rated susceptibility)

Check the following website:
www.astinco.com
Go to EMC menu and the ESD.
