IRF520 options

[GnG8d]

What would be the major disadvantage of using the higher wattage version?

IRF520N

IRF520PBF

 

[Robb]

Extra load on the voltage regulator?

 

[GnG8d]

Because it can dissipate more heat?

 

[Robb]

Because it will draw far more current than the stock regulator will deliver?

 

[GnG8d]

Not according to the data sheet.

 

[Robb]

Well, if a 30w final draws about 2.75 amps; then a 60w final would need to draw twice that.
How much is the typical regulator rated for?

If it works; then let's hear about it . . .

EDIT:

Seriously though, that could be way cool.
Is this a new device on the market?

 

[GnG8d]

Who's talking about a 30w transistor, and who said it would work?

 

[Robb]

Isn't this device used for RF?

 

[GnG8d]

You're losing me. Both devises are designed for a 50w circuit, according to the data sheets ..... you read those, right? Absolute maximum is 48w on one, and 60w on the other, so I'm not sure what 30w transistor you're talking about.

 

[Robb]

That is what happened. I just read the data sheet on the PBF device.

Well, I've determined that although there does seem to be some electrical differences, the PbF device is basically an IRF520NPbF ........... Pb=lead/F=Free.
