Very interesting, I wasn't aware of these puppies. I have 5V 100mA mechanical relays similar to these:

they have these things..... SSR (solid state relay) 4 pin dip..... >1 amp, 60 v...... this is at Digikey but should be able to get most anywhere

My requirements:
- can easily handle 800mA at 9V (to drive a solenoid),
- will be used in single bursts, not continuously,
- can be triggered using 5V signal,
- low cost,
- small footprint (as...
data sheet said 5v solenoid is about .7 amps.... 700 ma, and that opto thing data said 30 ma continous..... need a better driver ckt, can use a transistor or a DIP ss relay good for up to 1 amp
I’m using this circuit.
When the button is pressed, the relay switches on for one second and then turns off.
It doesn’t matter whether the button is pressed briefly or held down - the circuit...
