ESD8D3.3 thru ESD8D12 Surface Mount TVS For ESD Protection Diode P b Lead(Pb)-Free General Description: The ESD8D Series is designed to protect voltage sensitive components from ESD. Excellent clamping capability, low leakage, and fast response time provide best in class protection on designs that are exposed to ESD. Because of its small size, it is suited for use in cellular phones, MP3 players, digital cameras and many other portable applications where board space is at a premium.
