SMF5.0AT1 Series

Zener Transient

Voltage Suppressor

SOD−123 Flat Lead Package

The SMF5.0A Series is designed to protect voltage sensitive

components from high voltage, high energy transients. Excellent

clamping capability, hi gh surge c apability, low zener i mpedance a nd

fast response time. Because of its small size, it is ideal for use in

cellular phones, p ortabl e d evi ces, b us iness m achines, p ower supplies

and many other industrial/consumer applications.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.
