Thyristor Surge Suppressors

High Voltage Bidirectional TVS Devices

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.

Motorola Thyristor Device Data

Peak Repetitive Off–State Voltage — Maximum

On–State Surge Current — Maximum Nonrepetitive (MMT10V400 – 20 C to 65 C)

Rate of Change of On–State Current — Maximum Nonrepetitive

Operating Temperature Range

Overload Junction Temperature — Maximum

Thermal Resistance, Junction to Case — Maximum

Thermal Resistance, Case to Ambient, Without Heatsink

These transient voltage suppression (TVS) devices prevent overvoltage

Applications include current loop lines in telephony and control systems,
