Hmm, I missed that, even though it was there in the Subject. I was thinking that small stuff like ignition noise was all the suppressor diode had to handle. My bad. :-) Andy

Load dump can last for a long time. TVS is NOT generally used for load dump protection, just because of that. Instead, the emphasis is on using components (capacitors and voltage regulators) that will

Hi Andy Hmmm, load dumps can last a looong time. The large inductance field has to decay before the alternator stops producing the over voltage. 100s of mS, long enough to fry the TVS? Sorry for

LTspice DOES NOT generate values at uniform sample times. So, "previous sample" (in the context of LTspice computation) makes little sense. If you do want to evaluate in terms of a sampled data

Hi eqmqiq Ohms law says that your current is over 20A Quite a lot for a little TVS. Theyre usually meant for short spikes. 20A * 36V = 720W That would convert youre TVS into a SED in short order.

Look at the line that starts the definition of the subcircuit. ? ? .SUBCKT 06HPR33 1 2 3 You will notice that the subcircuit has 3 external nodes (1 2 3). The native inductor has only two external

Hi all, I would like to create the integrate and dump in LTspice (the same with integrate and dump block in Matlab). I can create the integrate by the equivalent idt() with bv.asv. However, I do not

Hi Ferdian Cahyodwiputro. I created a small electronic circuit to test the model. Using this scheme, I found that the description of the transistor pins are in non-standard order. I will put circuit
