Littelfuse SD22 950W Discrete Unidirectional TVS Diode

Littelfuse SD22 950W Discrete Unidirectional TVS Diode is designed for electronic equipment in low-speed and DC applications. It protects sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The SD22 diode safely absorbs repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation. It also safely dissipates 27A of 8/20μs induced surge current (IEC 61000-4-5 2nd edition) with very low clamping voltages. Littelfuse SD22 950W Discrete Unidirectional TVS Diode is halogen free, lead free, and RoHS compliant. Applications include switches and buttons, test equipment and instrumentation, medical equipment, computer peripherals, and more.
