I'm trying to find a small, affordable, solid-state SPST relay that I can use for an Arduino project. I've made an analog clock using regular electromechanical relays, and it works fine. But the clicks (once every 15 seconds) are driving (especially) my wife and me crazy!
I have found a 6-pin DIP SSR, a Panasonic chip called "AQV210E" (https://www.digikey.com/product-detail/en/panasonic-electric-works/AQV210E/255-1143-5-ND/251915), with a detailed description that reads: Solid State SPST-NO (1 Form A) 6-DIP (0.300", 7.62mm)
It looks to me as if the AQV210E will work, as long as I use appropriate resistance for its input (Arduino uses +5v or 0v digital pin output signal, and this chip's input is rated for only 1.14vdc). It seems to me (I admit I'm a novice/hobbyist) that the input of this chip should behave just like any LED being powered by a 5vdc signal... correct resistance between Arduino digital pin output and AQV210E chip input should allow successful On/Off behavior without frying the AQV210E.
Output-wise, I'll be making and breaking a ground connection for one or two LEDs at a time, so very little current is involved. The AQV201E isn't a zero-crossing relay, and it appears to be useful for a DC in / DC out application.
Can someone tell me if this AQV210E chip might work for me?
