Description
The ASDXXC is designed to replace multilayer varistors
(MLVs) in portable applications such as cell phones,
notebook computers and PDA’s, using monolithic silicon
technology to provide fast response time and ultra low
ESD clamping voltage, making this device an ideal solu-
tion for protecting sensitive semiconductor components
from damage. The ASDXXC complies with the IEC 61000
-4-2 (ESD) with ±30kV air and ±30kV contact discharge.
The ASDXXC is assembled into a lead-free SOD-323
package and will protect one unidirectional line. These
devices will fit on the same PCB pad area as an 0805
MLV device.
