Littelfuse SLD5S Unidirectional Surface Mount TVS Diodes
Littelfuse SLD5S Unidirectional Surface Mount TVS Diodes are designed to protect sensitive electronics against ESD, EFT, and 10/1000 surge events. SLD5S components also protect against inductive load switching voltage transient events for severe Automotive Load Dump applications. These Littelfuse TVS Diodes are housed in an SMTO-263 package with lead modifications.
