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 V_C(Clamping voltage) to the actual BV

(Breakdown Voltage) as measured on a specific device.
