SP3145 - TVS Diode Arrays

General Description

The SP3145 represents an industry first: unidirectional ESD protection in a 01005 type package.

Unidirectional protection should be favored over bi directional performance, particularly on logic and data lines, which typically do not transit zero volts during standard operation.

Key Features

  • ESD, IEC 61000-4-2, ±20kV contact, ±25kV air.
  • EFT, IEC 61000-4-4, 40A (5/50ns).
  • Lightning, IEC 610004-5 2nd edition, 1A (tP=8/20μs).
  • Low capacitance of 0.35pF (@ VR=0V).
  • Low leakage current of 20nA (MAX) at 2.8V.
  • Industry-first unidirectional protection, critical for data line protection, and any interface which does not transit zero volts.
  • Industry’s smallest single channel form factor, nominally 01005.
  • Halogen free, Lead.

TVS Diode Arrays (SPA®Diodes) Low Capacitance ESD Protection - SP3145 Series SP3145 Series 0.35pF 20kV Unidirectional Discrete TVS RoHS Pb GREEN Description The SP3145 represents an industry first: unidirectional ESD protection in a 01005 type package. Unidirectional protection should be favored over bi directional performance, particularly on logic and data lines, which typically do not transit zero volts during standard operation. Fast-acting, semiconductor based technology can withstand multiple ESD events, without wear-out or degradation. Low nominal capacitance makes this product meaningful for interfaces running at high data rates, approaching 5 GHz clock speeds.
