Preferred Devices
Thyristor Surge Protectors
High Voltage Bidirectional TSPD
http://onsemi.com
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.
