HI Everyone, It's that time of the month again. Here is my latest Technical Tidbit: Technical Tidbit - November 2010 Comparison of Current Waveforms from 150 Ohm and 330 Ohm Networks in an IEC 61000-4-2 Simulator This month's Technical Tidbit compares the discharge current of a modern IEC 61000-4-2 ESD simulator for 150pF/150 Ohm and 150pF/330 Ohm networks. Both ofthese networks have been used recently for applying a system level ESD testto individual solid state devices. Abstract: IEC 61000-4-2, the equipment level ESD testing standard, recently has been applied to individual solid state devices, a controversial use of the standard and despite there being no instructions in the standard on applying it to individual devices. In addition, some buyers are also insisting on an older 150 pF/150 Ohm network instead of the current 150 pF/330 Ohm network. Waveforms are presented comparing the current discharge of the two networks as supplied with a modern ESD simulator.

The picture of an ESD current measurement is the linkto the article. Doug -- ------------------------------------------------------- ___ _ Doug Smith \/ ) P.O.
