1 / 2 page NTE4903 thru NTE4999 Surge Clamping, Transient Overvoltage Suppressor Bidirectional 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 integrated 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.
