I'm a bit concerned about spacing between pads. The device states it is able to switch voltages as high as 220V. The QFN package has spacing between the pads is nominally 0,25mm. This is violating norms about PCB spacing vs. voltage, the least strict norm I found states that 0,4mm spacing is

Nick, note that the 3.4W are "absolute maximum" which usually means the part is going to die if you go over that. The part it self needs only 5V@25mA (when switching) plus the losses of the hv switches. In a nixie clock i guess there are always only 3 outputs on per chip. I use the plcc

I'm bidding on this auction... I mainly want XN-12 for collection, so if i win the auction, i offer two of the XN12 to the group for trading or a fair price. Vice versa, if anyone out of the group gets this auction, i would be very interested to buy or trade a XN12 for my collcetion! -- You

My guess is that the usually known norms are only meant for AC Mains Voltage where you have to expect 220V RMS, meaning the peak is around 350V and you have to calculate with multiple kA short-circuit current in case of a short circuit. Since Microchip clearly does not target hobby

I use the HV9808. 32 bits, hardware blanking, 5v control lines. Just set VPP to, say, 75V using a zener. Easy Peasy to program using an Arduino and the SPI library. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group

[neonixie-l] Re: XN-12s on Ebay

Jonathan, I would be very surprised if it closes any where near the current bid as there will be quite a few people after those XN-12s to either make up a set or to add to their collections. Good luck with it! On Sunday, October 29, 2017 at 9:20:21 AM UTC, SWISSNIXIE - Jonathan F. wrote: > >

Here is a closer view of what I believe to be ZM1175s in that offer. The CD66 has a different anode mounting tab compared to these. Could be wrong though.

Having a thermal pad does wonders. A PLCC package, in socket or not, has to dissipate heat mainly through its body, because heat transfers to other parts of the board only via legs. In practice, almost all power is dissipated through plastic. Thermal pad allows to mostly transfer the heat to
