AFAICT there are two main clamping mechanisms - first one for the logic ...https://electrical.codidact.com/posts/278989ESD Protection - Differential Amplifier 2kindhttps://electrical.codidact.com/users/534692020-11-06T16:41:23Z2023-08-10T11:59:54Z<p><img alt="Circuit under discussion" src="https://electrical.codidact.com/uploads/sW2MvmGsPEMrtont8Pk3op9y"></p>

It is a common dimmer with a triac/diac/pot of the simplest configuration (the triac is a BTA16). After replacing the triac, this still does not w...https://electrical.codidact.com/posts/280537MOV vs. TVS diodePete Whttps://electrical.codidact.com/users/536612021-01-21T14:21:53Z2023-07-30T19:09:19Z<p>Simple thing that I realized I should know but do not -- when is an MOV preferable to a TVS diode (with some associated network to really make it work, in both cases)? Is it even something to ro...https://electrical.codidact.com/posts/288404Variant of a Mosfet's Gate-Source protectionkellogshttps://electrical.codidact.com/users/603992023-06-13T19:35:52Z2023-06-14T13:03:29Z<p>Let's say a 100V voltage spike arrives at +12V and the TVS diode clamps it to 25V. Q2 may or may not be activated. Will this circuit ensure a V_gs lower than 25V for the mosfet Q1 ?
