Preferred Devices

Thyristor Surge Protectors

High Voltage Bidirectional TSPD

These Thyristor Surge Protective devices (TSPD) prevent

overvoltage damage to sensitive circuits by lightning, induction and

power line crossings. They 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.

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.

1. Allow cooling before testing second polarity.

2. Measured under pulse conditions to reduce heating.
