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.

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.
