Currently having problems with a triggering device I am working on for an engineering project. I'm attempting to use an IRD510 which I have read a couple of things on this forum to state it might not work correctly, I'm looking for detailed feedback. Two formats, first is testing, second is the actual device.
Diagram 1:
This shows a 3v(2x1.5v AAA's) power source on the left used as the gate voltage. 6v(lithium-ion) source on right goes into drain and out source of the IRD510 to the 1.9-2.4v/20mA LED pushing a 220ohm resistor(only one I had at the time and is cutting voltage to ~1.6v). Out of LED configuration and back to ground.
This seems to not light LED with the 3v source but works fine with 6v source, but sometimes the LED lights without power being applied, very odd timing. The LED system is going to be replaced with a Nichrome Wire wrapped around a 550lbft parachute cord. See second diagram.
Diagram 2:
The trigger for the gate on the final product is a bluetooth serial device. It will lay idle until we are ready to activate the "burn cycle" and then it will send a stream of serial data (pushing up to 3v but minuscule amperage) to trigger the gate. Then the mosfet or transistor will need to conduct 6v and up to 3-5amps of current to heat the 6-12inches or so of 28ga ni-chrome wire(approx 6.5ohms/ft) to 2000degreesF.
If the IRD510 is not appropriate is there a possibility one of the following transistors would be an appropriate replacement or can someone suggest a way this will work with parts available from a local Radioshack. The project is in the final week and half until it needs completed and I do not have time to order from Mouser or Digi-Key or the like. I'm a Mechanical Engineering not Electrical so I am not as well versed in the intricate electronic parts. Advanced thanks for any help.
Available transistors in my shop: TIP42(PNP), TIP120(Darlington), TIP3055(NPN), and a LM317T-Positive Adjustable Voltage Regulator. If the serial data voltage could be amplified to trigger the IRD510 then I would need advice on method of amplification.
