Surge Clamping, Transient Overvoltage Suppressor  
Unidirectional  
Description:  
The NTE4900 series of silicon Transient Suppressors designed to protect voltage sensitive compo-  
nents from high energy voltage transients. Transient over voltage suppressor devices have become  
very important as a consequence of their high surge capability, extremely fast response time, and low  
incremental surge resistance (Rs).  
Application:  
The NTE4900 series has a peak pulse power rating of 1500 watts for one millisecond can protect inte-  
grated circuits, hybrids, CMOS, MOS, and other voltage sensitive components in a broad range of  
applications such as telecommunications, power supplies, computers, automotive, industrial, and  
medical equipment.

Electrical Characteristics:  
Clamping Factor: 1.33 @ full rated power  
1.20 @ 50% rated power  
The clamping factor is defined as: The ratio of the actual VC (Clamping voltage) to the actual BV  
(Breakdown Voltage) as measured on a specific device.
