μClamp™ 4-Line ESD Protection

The μClamp™ series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD. It is designed to replace single line devices such as multilayer varistors (MLVs) in space constrained applications such as cell phones, notebook computers, and other portable electronics.
