I'd like to make something isolated and inline for a power cable ideally. Like the retired https://www.sparkfun.com/products/retired/12920</p>

Check out the hookup guide -- there are some pictures of the assembly. The diodes also have numbers written on them as well, 1N4148 would be marked:<p>41</p><p>48</p></p>

How do I tell which is the zener and which is the flyback diode? I'm assuming the smaller one is the 1N4148.</p>

The latter is two bucks more expensive, but needs a lot less power to drive and switches the load on zero crossings. The only thing this one has going is that it has on NC and one NO contact, but how often do you switch between two loads?</p>

In any case, no reasonable response because intended end-use environment not defined, and installation (O/V) category not specified, and conditions of acceptability not known. But here is a minimal list to start with:<ol>
<li>reference UL60065/60950-1/62368-1 for scoped end-use requirements.</li>
<li>reference UL796 for PCB requirements.</li>
<li>reference UL1977 for AC mains connector requirements.</li>
<li>reference NFPA70 (NEC) for wiring requirements.</li>

I tested an older version of this product on 3.3 volts and it worked fine, but since it's below spec, you may run into trouble. Give it a shot with 3.3 volts and if you're having trouble, bump the voltage on the 5V pin up to 5 volts and you should be good.</p>

You people are finally getting better at this, but SF and others should know that you and your ilk were the subject of several discussions at the IEEE Product Safety Engineering Society symposium (last month in Anaheim). The director of OSHA's NRTL program was there and listened with interest, as this stuff has been, as of late, starting to cross from the home workshop to the work-place.</p>

Electronics solder wire (including the one we sell and use in production) will often have a <a href="https://en.wikipedia.org/wiki/Flux_(metallurgy)#Rosin_fluxes" rel="nofollow">flux core</a> to allow better wetting and flow when you solder your parts in. The residue left after soldering is often a little sticky, slightly conductive, and may eventually corrode your board. It's a good idea to clean the board when you are done, just make sure you let the board dry completely before connecting it to power.</p>

It gives you proper spade terminals for the high current connections. I have replaced so many of these relays in different devices because they overloaded the bottom pins on the relay.<p>http://www.digikey.com/product-detail/en/JTN1AS-TMP-F-DC5V/255-1487-ND/303481</p></p>

The biggest difference I see is that on the output (hi voltage) side, there are now three connections, a common with normally closed and normally open outputs. The previous version only had the common connection with a single output. This new configuration seems to be much more flexible and allows for an either/or situation with two downstream outputs you want to control. I'm going to order a few.</p>
