I wish they would scale it down to DPAK

Hello Rama, I am conducting a search for one of my top clients focused on High Voltage IGBTs. I am offering a significant finders fee if someone is able to help me with this position. Are you available for a phone call next week?

80mOhm for a 1200V device, now that's something to crow about. MOSFET's have around an Ohm and IGBT's a a fixed ~2V loss which this device wouldn't see until ~25A. Sounds almost too good to be true. I want one :-)

It's nice to see these coming online finally, and depsite the expense they should see a healthy market, especially in solar power apps. One comment: No mention is made of up-and-coming GaN devices---of course they are just becoming available, and at relatively modest power levels, so perhaps fair enough. In the beginning of the piece, the on resistance is expressed in mV. Of course that is a typo and should be milliohms.

Besides spreading good white light, CREE has been the first to add the shine of a diamond to power mosfets.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
