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.
` Allow cooling before testing second polarity.
` Measured under pulse conditions to reduce heating.
DescriptionThese MMT08B064T3 Thyristor Surge Protective Devices (TSPD) prevent overvoltage damage to sensitive circuits by lightning, induction and power line crossings. MMT08B064T3 are breakover-triggered crowbar protectors. Turn-off occurs when the surge current falls below the holding current value.Secondary protection applications for electronic telecom equipment at customer premises.
