Bourns® TISP® Thyristor Surge Protectors are surge protective devices with characteristics very different than the normal SCR (Silicon Controlled Rectifier) and TRIAC (Triode for AC Control) type thyristors. Thyristor Surge Protector Device current parameters cover a range from a few nanoamps to hundreds of amps. A similar situation exists for thyristor SPD voltages, where there can be a wide range from several volts to hundreds. These TISP products are specially designed to provide protection for telecommunications equipment in instances where high voltages occur as a result of lightning strikes, power line crosses, or a/c power surges.
Featured TISP Product
TISP61089M dual forward-conducting buffered p-gate overvoltage protector is designed to protect monolithic SLICs against overvoltages caused by lightning, a.c. power contact, and induction. This Bourns dual voltage-programmable protector features high 70A 5/310 capability and supports voltages down to -155V. It also offers low 5mA gate triggering current and high 150mA holding current. TISP61089M limits voltages that exceed the SLIC supply rail voltage.
