Highly Stable and Reliable Surface Mount PAR® Transient Voltage Suppressors (TVS) DO-218AB SM5S

Short Description:

Product No.:  DO-218AB SM5S   

Introduction: Highly Stable and Reliable Surface Mount PAR® Transient Voltage Suppressors (TVS) DO-218AB SM5S, whose chip is processed by Chemical Etching Method and PN junction is protected by PI glue without the side effect of cutting stress and rough edges, has strong reverse surge capability as well as even electricity field of chip with high vertical integration on the lead, base and chip package. It can function normally under the temperature of 175. Highly Stable and Reliable Surface Mounting Transient Voltage Suppressor (TVS) DO-218AB SM5S is used in sensitive electronics protection against voltage transients induced by inductive load switching and lighting, especially for automotive load dump protection application.
