TVS Diode Arrays (SPA Diodes) Low Capacitance ESD Protection - SP3145 Series RoHS Pb GREEN SP3145 Series 0.35pF 20kV Unidirectional Discrete TVS ESU270-51 06/10th/2020 - Description The SP3145 represents an industry first: unidirectional ESD protection in a 01005 type package. Unidirectional protection should be favored over bi directional performance, particularly on logic and data lines, which typically do not transit zero volts during standard operation. Fast-acting, semiconductor based technology can withstand multiple ESD events, without wear-out or degradation. Low nominal capacitance makes this product meaningful for interfaces running at high data rates, approaching 5 GHz clock speeds. Pinout Features ESD, IEC 61000-4-2, Industry-first 20kV contact, 25kV air unidirectional protection, critical for data line EFT, IEC 61000-4-4, 40A protection, and any (5/50ns) 12 interface which does not Lightning, IEC 61000- transit zero volts 4-5 2nd edition, 1A Industrys smallest single (tP=8/20s) channel form factor, Low capacitance of nominally 01005 0.35pF ( VR=0V) Note: Drawing not to scale Halogen free, Lead free Low leakage current of and RoHS compliant 20nA (MAX) at 2.8V Functional Block Diagram Applications Mobile Phones Wearable Technology Smart Phones Portable Navigation 1 Components Camcorders Tablets Portable Medical Point of Sale Terminals Digital Cameras 2 Life Support Note: Not Intended for Use in Life Support or Life Saving Applications The products shown herein are not designed for use in life sustaining or life saving applications unless otherwise expressly indicated. 2020 Littelfuse, Inc.
