Specifications of NTE4975

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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.
