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. Absolute Maximum Ratings: Peak Pulse Power Dissipation (TA +25C). 1500W tclamping (0 volts to BV Min). x 1012 sec Operating and Storage Temperature. to +175C Forward Surge Rating 200 Amps,. 1/20 Second at +25C Steady State Power Dissipation. = +25C Electrical Characteristics: Clamping Factor: 1.33 @ full rated power @ 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.

Electrical Characteristics (Cont'd): Clamping Factor: 1.33 @ full rated power @ 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.

Note 1. Normal selection of a zener transient over voltage suppressor is by rated standoff voltage (VWM) and should be equal or greater than DC or continuous peak operating voltage. Min.375 (9.52) Max
