Bourns TISP Thyristor Overvoltage Protectors

Bourns TISP Series Thyristor Overvoltage Protectors provide robust, fast-acting protection against transient overvoltages caused by lightning, power cross, and AC disturbances. These voltage-triggered thyristor devices clamp excessive voltage and switch to a low-impedance state, safely diverting surge current away from sensitive circuits. The TISP series thyristor overvoltage protectors are designed for telecom and data line protection and offer low capacitance, high surge capability, and stable crowbar performance to prevent latch-up. Typical applications include modems, gateways, line cards, and communication infrastructure.
