What's needed to fill in the gaps in understanding GaN HEMTs and their catastrophic failures. Degradation mechanisms that plague GaN HEMTs. Why overvoltage ruggedness and surge-energy withstand go ...

A Zener diode can be used as an overvoltage protector that shunts fault current through ground via a current-limiting resistor (Figure 2). Note that the Zener protection is effective only if the Zener ...

Gallium-nitride (GaN) high electron mobility transistors (HEMTs) have a limited avalanche capability. Thus, they may frequently experience catastrophic failures in voltage overshoot up to their ...

For amplifier applications which require overvoltage protection and also call for low distortion, low noise, and high bandwidth, engineers must pay careful attention ...
