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, high surge capability, low zener impedance and
fast response time. Because of its small size, it is ideal for use in
cellular phones, portable devices, business machines, power 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.
