 
	This high power 75 W Zener diodes BZY91 series, including models BZY91C75 and BZY91C68, provide voltage regulation in a selection over a 7.5 V to 75 V broad range of voltages. The heat sinking with their low thermal resistance. These devices have a very low forward voltage drop and a very fast switching feature. These devices have better efficiency and high switching speed.
