Hears what I am getting

1N4007 Rectifier Diode
IRFP350 400V 16Amp Mosfet
120 ohm 3 Watt Power Resistor


Will these work for powering Flybacks? AC and DC?

I have got the Coil.

Thanks for all the help

This is all I got, is it all I need?

Nope, you need an inductor too, roughly 100uH, one out of an old computer PSU should do the trick.
Those 1n4007's are going to get pretty warm, and I'm unsure if they are fast enough, you will kill them. I used MUR840's on mine, which are probably overkill?
You also need some Zeners to clamp the gates. 15Volt jobbies.

I think a lot of people use the UF4007 or something like that- its the same ratings as the 1N4007 but it is a lot faster and shouldn't get as warm or fry as easily.

If you need alot of one part you should try Ebay. Digikey.com and newark.com are also very good, but a bit expensive. In my ZVS i use these.

Okay my list is:
1. UF4007 Rectifier; 1.7V; 1A; 1000V; 700Voltage, RMS (40)

2. 1N5352B Diode, Zener; 15V; 5 W @ 75C (Ambient); DO-201AE; 2.5 Ohms @ 75 mA; 1; +175 (40)

3. Flyback Transformer ETF-30L316AYT (10)

4. 120 ohm 2 Watt Power Resistor (Pkg of 200) (1)

5. 120 ohm 3 Watt Power Resistor (Pkg of 50) (2)

6. IRFP350 400V 16Amp Mosfet (10)

7. 2uF 400VDC Film Capacitor (6)


I have the inductor and the coil, so will all this work?
