You need a TVS diode because many voltage regulators do not have the ability to sink current, nor can they respond fast ...

though sometimes the diode function is really implemented with on board JFETs. Let’s talk about CMOS logic families. The table below shows the curve between the newest families and obsolescence.

The addition of SiC JFET technology will complement onsemi’s extensive EliteSiC power portfolio and enable the company to address the need for high energy efficiency and power density in the AC ...
