Is ESD overhyped?
I have seen many engineers talk about ESD protection but I had never seen its effects myself. I made many small DIY projects and I have used bare hands to touch ICs and their pins,but nothing got destroyed(I mean ICs functioned well). Is it really that serious? Please tell and also its mitigating measures. I experimented with a mosfet just now by rubbing my fingers on its terminals. It is an n-channel mosfet called IRF510,and its datasheet is here . I observed that mosfet is working well by checking with a multimeter in diode mode i.e drain is connected to common of multimeter and source to positive one.
Yes, damage due to ESD (electro-static discharge) is real. Just because you haven't seen it isn't much evidence of anyt …

Yet another example. If using MOSFETs only for power switching applications, it can seem like these are "robust" and "i …

Many ESD problems are "latent" that is they do not sofort show up....some time later things will stop working :)

Just to let you know: if one day you have to use the LM337 negative voltage regulator, protect everything with TVS or Zeners. This is the most failing component I've ever seen (and I'm not the only one who thinks so, see youtube). I suspect strongly it is very sensitive to ESD. In my last application, after having replaced the LM337 for the 66th time, I protected it heavily and it finally stoped to fry.
