Benefiting from the Evolution in Power Transistors

One of the other treads was discussing the destruction of MOSFETs,
which motivated me to write these few posts, where I normally just
lurk here.

Related to my Magick Smoke post.

Benefiting from the Evolution in Power Transistors, such as Gate
Injection Transistors and Cascode Silicon Carbide Transistors.

Gate Injection Transistor:

"Panasonic PGA26E X-GaN Power Transistors

Panasonic PGA26E07BA and PGA26E19BA X-GaN Power Transistors are 600V
Gallium Nitride power devices based on Gate Injection Transistor (GiT)
technology. PGA26E X-GaN power devices deliver Normally-Off operation
with extremely high-speed switching characteristics and zero recovery
loss.

FEATURES
Crystal growth of X-GaN on 6" silicon substrate
600V enhancement mode power switch
Normally-Off operation with a single X-GaN device by proprietary Gate
Injection Transistor (GIT) technology
Extremely high-speed switching characteristics
Zero recovery loss characteristics"

Bob,

I was talking to a designer of a switching RF amp the other day.  I
asked him if he tried the new SiC chips rather than the MOSFET he uses
for the output.  He said he had tried a bunch but they don't last.  I
looked at his favorite FET datasheet and between the gate and source is
a pair of counter facing series zeners build into the wafer. I asked did
you try putting similar on the board, no he said space was lacking.

So if anybody is losing the magic smoke I suggest they try the Zener
trick and Ole can likely tell us the proper name of this protection
topology rather than smoke saver.
