NTE4950
TRANSIENT SUPPRESSOR, 43.6V

See also >>> NTE4902 thru NTE4998
Surge Clamping, Transient Overvoltage Suppressor Unidirectional

Description:
The NTE4900 series of silicon Transient Suppressors designed to protect voltage sensitive components 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.
