Generally zeners are not for high current suppression (unless you find one with a datasheet that says otherwise). Typically TVS (transient voltage suppression) diodes are used for this. Why don't you use a MOV (metal oxide varistor) like just about every other surge protector uses? You have to mount a thermal fuse next to and touching the MOV to open up the ...

Please note that 220 V was used 20 years ago. In Europe the standardized mains voltage is 230 V. Further: 230 V is the RMS value, therefore the actual voltage that feeds your circuit is: v(t) = 1.414 * 230 * sin(6.28 * f * t) You may use an inductor L of 10 to 200 micro Henry in series to the fuse. L will act as a resistor for transient events and will ...

they have not mentioned the value like 4kV, 6KV No they don't need to. EN 61000-4-5 specifies various different voltage levels and it is down to the designer to select the one that is appropriate and then choose the right TVS. The TVS in your question is this and, outlined in red is the important information: - It is the important information because, for ...

Vcl is the clamping voltage. It means that should a lightning strike occur, the max voltage on the rail will be about 93.6V (provided the skrike complies with the stated models. Which it generally should). According to the datasheet it is rated for IEC-61000-4-5 as seen from the snippet below: Basically, the datasheet guarantees that the diode complies with ...

The VCL is the clamping voltage of the TVS diode. This means that anything at or above the 93.6V will be effectively shorted. The answer is yes, this will protect against the high voltages that you mentioned.

The Joule rating for the power strip only tells you how much energy the protective element inside can absorb in an over-voltage situation and is mostly a marketing gimmick in my opinion. Most power strips will have a hard limit at 15A/1800W since that's the limit of the NEMA 5-15P plug. Occasionally, you can find one with a 5-20P plug on the end (neutral ...
