Description

The protectssensitivesemiconductorcomponentsfromdamage orupsetduetoelectrostaticdischarge (ESD)andothervoltage inducedtransient events. They feature large cross-sectional area junctions for conducting high transient currents, offer desirable electrical characteristics for board level protection, such as fast response time, low operating voltage. It gives designer the flexibilityto protectone bi-directional line inapplications where arrays are not practical.
