Excellent!
Yeah, that's why I considered the opto-couplers at first; to isolate the solenoid from the 5V circuit, but I'll be using separate sources:
- 5V from TPS56637 (for PICs, LEDs, and all...
Using datasheet:

My work so far:
I added tD(ON) and tr to get total t
Google AI says:
Ig = Qg / t
.. yes the 'AO3400A' are good for what you want, and the very low '0n resistance' means most all the voltage will be on the coil, which is what you want. The only thing about the SSR's is that the...
amgen Yesterday, 23:40Very interesting, I wasn't aware of these puppies. I have 5V 100mA mechanical relays similar to these:

I'll...
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...
Yeah, about that. Solenoid barely moves at 5V. I just tested on a bench PS and it really starts working closer to 7V. 9V and it gives a nice "snap".
I'd love to find a transistor like the...
Yeah, I quickly dropped the MCT6 when I checked the specs.
I toyed with the 2N7000, but I've since switched to a IRF730A mosfet; works flawlessly (I just have to properly calculate the base...
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

Re: New project - MSFS C++ USB interface
One of the challenges I had given myself was to simulate an electric breaker in MSFS, just like the ones in a Cessna 152.
