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 V_C(Clamping Voltage) to the actual BV

(Breakdown Voltage) as measured on a specific device.
