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.

Features

  • AEC-Q101 qualified with automotive-grade (PPAP capable)
  • SMTO-263 package and footprint is compatible with the industrial popular DO- 218AB package
  • Meets 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 TO-263 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 mount applications to optimize board space
  • Low profile package
  • Matte tin lead–free plated
  • Halogen-free and RoHS compliant
  • Lead-free E3 means 2nd level interconnect is lead-free and the terminal finish material is tin (Sn) (IPC/JEDEC J-STD-609A.01)
