Description
The ASD33L-40L is designed to replace multilayer varis-
tors (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 ASD33L-40L complies with the IEC
61000-4-2 (ESD) with ±30kV air and ±30kV contact dis-
charge. The ASDXX 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.
