SuperESD - SELC3Dxx1BA
1. Description
The SELC3Dxx1BA Series are ultra-low capacitance transient voltage suppressor arrays, designed
to protect applications such as portable electronics and smart phones. This series is available
bidirectional configurations and is rated at 300 Watts for an 8/20us waveshape. At higher operating
frequencies or faster edge rates, insertion loss and signal integrity are a major concern. This series
offers a ultra-low capacitance and low leakage current in a miniature SOD-323 package.
