Datasheet

## **NTE4903 thru NTE4999 Surge Clamping, Transient Overvoltage Suppressor Bidirectional** 

## **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.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
