Features

The SZP6SMB series is designed to protect voltage sensitive

components from high voltage, high energy transients. They have

excellent clamping capability, high surge capability, low breakdown

impedance and fast response time. The SZP6SMB series is

supplied in the Littelfuse exclusive, cost-effective, highly reliable

package and is ideally suited for use in communication systems,

automotive, numerical controls, process controls, medical

equipment, business machines, power supplies and many other

industrial/consumer applications.

Maximum Ratings and Thermal Characteristics

Stresses exceeding those listed in the Maximum Ratings table may damage the component. If any of these limits

are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.
