The new components offer circuit designers the important benefits of lower component count and board usage, reduced EMI, optimal clamping at all loads and higher efficiency. Introducing The new ZenBlock combines the double diode snubber in one package. This leads to the following advantages: 
-Fewer components. 
-Reduced circuit board space 
-Lower EMI by reducing the drain clamp circuit length and area. 
-Optimal clamp performance at all loads (compared with RCD and RC snubber) 
-Higher efficiency at low loads (compared with RCD and RC snubber) . Previous circuit related to this circuit : Protection of the Mosfet in flyback power supply
