Shield Gate Technology Gen 2 enables 100V 3.6mOhm MOSFET

November 09, 2017 by Paul Shepard

Alpha and Omega Semiconductor Limited (AOS) today announced the release of AONS66916  production utilizing  the latest Alpha Shield Gate Technology Generation 2 (AlphaSGT2). The AONS66916 has best-in-class RDS(on) * Qg  (FOM) and more robust capability for a greater safety margin.

In synchronous rectification, it is essential to optimize the reverse recovery charge and reduce the voltage overshoot. These attributes enable higher efficiency and robustness to critical high density telecom and server applications.

The AlphaSGT2 provides ~30% lower RDS(on) compared to AlphaSGT1 and is designed to be more robust with significant avalanche energy improvement. AlphaSGT2 technology reduces both conduction and switching losses.

Thus, with AlphaSGT2 technology, circuit designers can prevent paralleling devices for lower turn-on resistance, enabling higher power density in power supply applications.

"The new AlphaSGT2 100V technology is designed for critical applications such as Telecom and Datacom power supplies where power density, high efficiency, and robustness is essential," said Peter H. Wilson, Director of Product Marketing at AOS.
