ERF9530 RF Power Mosfet Transistor, 100 Watts PEP, 30 MHz, TO3PN Case

The ERF9530 feature new silicon wafer designs with greatly improved quality and durability. Palomar’s new wafer technology creates a new level of ruggedness for these RF power MOSFETs that are now able to withstand all adverse conditions - high heat, high VSWR, high voltages and current levels.

The ERF9530 is a drop-in replacement and upgrade for the ERF7530 transistor and features a new TO-3PN insulated package for the mounting screw. The ERF9530 is conservatively rated at 100 watts PEP.

FEATURES
• High Power and Economical:
Pout > 25W (100W PEP)
Gp > 10dB @ 12.5V, f=30MHz

MFR: Palomar
 
I guess these too have been discontinued so I have heard. Trying to find a place that still has some in stock so I can buy a couple to hang on to. I have two radio's with the RFX75 on them and I want to be able to get them fixed should I ever blow a final. Any help would be great.

ERF9530 upgrade drop in replacements .......
 
Normally you see that part used in audio amps when paired with a 2SD1047 you can expect about 100w out of a pair per ch. You have to match them though because the hfe is all over the place with them anywhere from 60-240. I have not see anyone use that part for RF. I have seen them used in power supplies in the past.
