TVS TVS Diode Diode ArraysArrays (SP(SPAA Diodes)Diodes) Surge Protection - SD22Surge Protection - SD22 SD22 Series, 950W Discrete Unidirectional TVS Diode RoHS Pb GREEN Description The Unidirectional SD22 Series is designed for use 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 SD22 series can safely absorb repetitive ESD strikes at 30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 27A of 8/20s induced surge current (IEC 61000-4-5 2nd edition) with very low clamping voltages.
