SLD8S Series
Description
The SLD8S SeriesTVS Diode is housed in a SMTO-263
package with lead modifications. It is designed to protect
sensitive electronics against lightning and inductive load
switching voltage transient events for severe Automotive
Load Dump applications.
Features
• AEC-Q101 qualified
capability
• SMTO-263 package, and
foot print is compatible to
industrial popular DO-
218AB package
• Meet ISO7637-2 5a/5b
protection and ISO16750
load dump test (refer to
APP note for details)
• Low incremental surge
resistance
• UL Recognized compound
meeting flammability
rating V-0
• Meets MSL level 1, per
J-STD-020, LF maximun
peak of 260°C
