Let me preface by saying that I'm clueless when it comes to this. I hope this is the correct place to post this.
I'm working on a project from years ago and I don't remember much about the development of it. I handled the actual building of the boards and my friend did the pcb layout.
It was a board for a paintball gun. Voltage was regulated to 5v. When you'd flip a switch, it would fire a solenoid. I've listed some details about the designs below, but the old board built with the 8051 chip would fire any solenoid you hooked to it. The second design used pretty much the same circuit and used the same voltage regs, caps, etc, but for some reason switched to the 355 part. One was an N and one was a P channel. The atmega board with the 355 wouldn't fire the bigger solenoids that the previous design would.
I had a project that used an atmel 8051 chip and this transistor MMBT3906
Due to the 8051 becoming obsolete, we switched to an atmega8 and used this mosfet 355an
I feel like the 355 doesn't allow the same amount of current as the other part, but I honestly have no clue.
I'm hoping someone could point me to a part that would drop into the 355 spot, but possibly provide more power. Like I said, I do not have a clue about this and it might not even be possible.
Could anyone help?
