Other Parts Discussed in Thread: TPD2E009

Hello:

I am new to ESD standards. Can I have a clarification when to test at 4KV/8KV or 8KV/15KV for contact/air respectivelly?

What is the difference between IEC 61000-4-2 and EN 50082?

    Hi Oscar.

    IEC 61000 is an international standard; its counterpart in the European Union is EN5008x. While most customers care about IEC 61000 standards, some care follow the EN5008x.  

    Specifically, EN 50082-1:1991 Generic Immunity Standard consist of Electro Static Discharge (ESD), Radio Frequency (RF) and Electric Fast-Transient Burst (EFT), which is the IEC61000-4-2, IEC61000-4-6, IEC61000-4-4, respectively, in the IEC standards.

    Electro Static Discharge deals with the static charges that can build up in normal operation to several kilovolts and stresses the electronic components. The test is performed with 4 kV for Direct Discharge and 8 kV for Air Discharge.

    The RF Immunity refers to the ability of the equipment to work undisturbed in a RF field (electromagnetic field) between 27 to 1,000 MHz, with 80% AM (amplitude modulation), and for Light industrial environments a 3 V/m Stress level is used, or 10 V/m for Heavy industrial environment.

    Fast-Transient Burst is related to the high voltage transients developed on the powerlines as a result of switching heavy equipment, lightning, and power outages. Test are performed with 1 kV burst at 5 kHz for power lines, and 0.5 kV burst to signal lines in case of Light industrial equipment, or 2 kV burst for power, and 1 kV to signal lines for Heavy industrial equipment.

    Hello Roger:

    I am currently using TPD2E009 in an application; the customer is asking to test the unit for contact discharge at +/-8KV and air discharge at +/-15KV. I know the TPD2E009 is only rated at +/-8KV.

    Is the request to test air dicharge at +/- 15KV valid per IEC6100-4-2? I have found many reference to 4 and 8 KV testing, but not 8 and 15 KV testing.

    Thanks, Oscar.
