The SLD5S unidirectional TVS Diode series is housed in a SMTO-263 package with lead modifications. It is designed to protect sensitive electronics against ESD, EFT, 10/1000 surge events and inductive load switching voltage transient events for severe Automotive Load Dump applications.

Features

  •  AEC-Q101 qualified with automotive grade (PPAP capable) 
  • SMTO-263 package, and foot print is compatible to industrial popular DO218AB package 
  • Meet ISO7637-2 5a/5b protection, ISO16750 and JASO D-001 load dump test (refer to APP note for details) 
  • VBR @ TJ = VBR@25°C x (1+αT x (TJ - 25)) (αT:Temperature Coefficient, typical value is 0.1% 
  • Glass passivated chip junction in modified TO263 package 
  • ESD protection of data lines in accordance with IEC 61000-4-2, 30kV(Air), 30kV (Contact) 
  • EFT protection of data lines in accordance with IEC 61000-4-4
  • Fast response time: typically less than 1.0ps from 0 Volts to VBR min 
  • Excellent clamping capability 
  • Low incremental surge resistance 
  • UL Recognized compound meeting flammability rating V-0 
  • Meets MSL level 1, per J-STD-020, High temperature reflow soldering guaranteed: 260°C/10sec at terminals 
  • For surface mounted applications to optimize board space 
  • Low profile package 
  • Matte tin lead–free plated 
  • Halogen free and RoHS compliant 
  • Pb-free E3 means 2nd level interconnect is Pbfree and the terminal finish material is tin (Sn) (IPC/ JEDEC J-STD-609A.01)

Applications

Designed to protect sensitive electronics from: 

  • Inductive Load Switching
