These robust diodes can safely absorb repetitive ESD strikes at ±30kV (contact and air discharge, IEC 610004-2) without performance degradation. Additionally, each diode can safely dissipate 80A (SC1105) of 8/20μs surge current (IEC 61000-4-5 2nd edition) with very low clamping voltages. ## ~~**Pinout and Functional Block Diagram**~~ PIN1 PIN2 ## ~~**Features**~~ - ESD, IEC 61000-4-2, - ±30kV contact, ±30kV air - EFT, IEC 61000-4-4, 40A (5/50ns) - Lightning, IEC 61000- - 4-5 2[nd] edition, 80A (tP=8/20μs, SC1105) ## ~~**Applications**~~ - Switches / Buttons - Test Equipment / Instrumentation - Point-of-Sale Terminals - Low clamping voltage - Low leakage current - Moisture Sensitivity Level(MSL -1) - Lead free and RoHS compliant - Medical Equipment - Notebooks / Desktops / Servers - Computer Peripherals 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.
