G'day Hernanstafe,
The amp modules in question will work well with any mosfet device in the same series as the IRFP450. I.e; IRFP250, 350 etc. Other mosfets can be used too provided they are a TO247 package. Minimum specifications are; Vds minimum = your peak to peak idle rail voltage + 20%. For 70 volts rails this is 168 volts. Pd minimum @ 25 degC = 180w Low gate capacitance (relatively) Cheers |
