TVS Diode Arrays (SPA® Diodes) General Purpose ESD Protection - SD Series
SD Series 450W Discrete Unidirectional TVS Diode
RoHS Pb GREEN
The SD series is designed to replace multilayer varistors (MLVs) in electronic equipment for low speed and DC applications. It will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The SD series can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 30A (SD05) of 8/20μs induced surge current (IEC61000-4-5) with very low clamping voltages.
