[Star Wars] Why was the electro-proton bomb never used again after the Battle of Malastare?

In the Clone Wars TV show, season 2 episode 18, we see the Republic use a brand new bomb that can disable electronics in a huge area. This EMP in the Battle of Malastare was extremely effective, disabling an entire army of droids in only seconds. This seems like it would be a huge game changer. 

I understand that the bomb had two unfortunate side effects. One, it disabled all electronics regardless of side. And two, it released the Zillo beast, a huge monster capable of tremendous destruction. 

But despite these drawbacks, I can see the weapon being enormously in space, detonating it in the middle of an enemy fleet would render them helpless. 

So why was it never used again?

Actually, electronics-disabling weapons are not uncommon at all in the Star Wars -verse. Remember the ion cannons used in defense of Hoth during episode 5, for example? *Because* they're common, however, most tech -- and certainly all military tech -- is shielded against ion blasts to some extent, and furthermore has automatic reset functionality that will restart a disabled vehicle or the like shortly after it's been shut down by EMP-like effects.

Since we don't know the full technological details of what made that bomb different, I'd wager part of it was its ability to ionize the air and thus effectively keep a constant EMP effect going on for a lengthy period of time, causing excessive damage to electronics and disabling them permanently. Thus, there's no guarantee that the device *would* work in space, or at least be comparably effective.
