												(VRD) is a transient voltage 
												suppressor device that is 
												designed to absorb voltage 
												surges and spikes that during 
												power initiation. Our VRD 
												features uniform avalanche 
												breakdown across the junction, 
												enabling very fast response to 
												surge voltage.
												Furthermore, its control voltage 
												is almost independent from the 
												current which makes it a highly 
												reliable, high performance 
												devices.
 
											
 
										 
										
											
											Applications
											
											- Protection of telecommunications 
											line and equipment from 
											lightning-induced surges 
											- ESD protection
											- EMP protection
											- Relays, solenoids, etc., switching 
											surge protection
											- Surge protection of fire alarms, 
											smoke detectors, etc.
											- Protection of electric circuits 
											from abnormal voltage conditions
