TVS Diode Arrays (SPA Diodes) Low Capacitance ESD Protection - SP0544T Series RoHS Pb GREEN SP0544T Series 0.5pF 12KV Diode Array 06/10th/2020 ESU270-51 - Description The SP0544T integrates 4 channels of ultra low capacitance rail-to-rail diodes and an additional zener diode to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). This robust device can safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (8kV contact discharge) without performance degradation. The extremely low loading capacitance also makes it ideal for protecting high speed signal pins such as V-By-One, HDMI, USB3.0, USB2.0, and IEEE 1394. Pinout Features ESD, IEC61000-4-2, Low capacitance of 0.5pF 12 GND 34 12kV contact, 25kV air (TYP) per I/O EFT, IEC61000-4-4, 40A Low leakage current of (t =5/50ns) 1.5A (MAX) at 5V P Lightning, IEC61000-4-5 Halogen free, Lead free nd 2 edition, 4A (t =8/20s) and RoHS compliant P 87 65 Functional Block Diagram Applications V-By-One Flat Panel Displays Embedded DisplayPort LCD/LED TVs USB 2.0/3.0 Ports Smartphones HDMI Mobile Computing 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.
