Surge Clamping, Transient Overvoltage Suppressor  
Unidirectional  
Description:  
The NTE4800 Series of high power transient suppressors are Silicon PN Junction devices designed  
for absorbtion of high voltage transients associated with power disturbances, switching and induced  
lighting effects. These devices were designed to be used on the output of switching power supplies  
and may be used to replace crowbar circuits.  
They are able to withstand high levels of peak current while allowing a circuit breaker to trip of a fuse  
to blow before shorting. This will enable the user to reset the breaker or replace the fuse and continue  
operation. For this type of operation, it is recommended that a sufficient mounting surface be used  
for dissipating the heat generated by the device during the transient or overvoltage condition.
