If it looks like 2 zener symbols tyed together at their cathodes I belive this is a avalanche diode or transient voltage suppressor (TVS). If you have a p/n you could do a search on like digikeys wesite and possible get an idea.

Woody, Daisy chain packages are definitely needed, but if you can get packages with a dummy chip inside these will provide a more accurate simulation of working components. If possible, continuous monitoring of resistance during the test will be

Cedric: I know you said "5KE36CA." Motorola, Fairchild, and some others make a zener transient suppressor 1.5KExxCA. The CA suffix makes it bidirectional. Actually, Motorola is no longer in the business. On Semiconductor (www.onsemi.com) sells t

You might want to check your input power. It is never "clean" but you might have too many spikes and transients. I've seen line monitors used and it was an eye opener how much noise there was on the input power. If you had a CPU go, you might want

Hi Has anyone has thermal capacitance model for QFN (9x9) package with exposed pad 7 x 7 (or 6 x 6). Ideally between junction and case, junction case and board (JESD51-7 or similar). I wish to do transient with spice, to established how long it tak

Transient Voltage Suppressors

AVX and a few other companies make these chip transient voltage suppressors (TVS) parts that are a real *PAIN* to use. According to AVX: "Due to the semiconducting nature of the doped Zinc Oxide (ZnO) ceramic material, SMT TransGuards are no

I'm looking to find a traning course for PCB design & layout

Hi! I'm looking to find a training course for PCB design & layout. It would be prefer to be in Canada, if such courses are available here... if not I'll go where ever I have to. The course should be about the following points or more: -Crosstalk -cou
