Features

  • 5.0V breakdown for 5V rails
  • 200W peak pulse power
  • IEC 61000-4-2 +/-30kV ESD
  • 9.2V clamping voltage
  • SOD-123FL flat lead package

  • RoHS compliant

Applications

  • 5V power rail ESD/surge
  • USB VBUS protection
  • MCU VDD clamp
  • Industrial 5V supply protection

The SMF5.0A from Littelfuse is a 5.0V unidirectional TVS diode in SOD-123FL package. 200W peak pulse power handles IEC 61000-4-2 ESD and IEC 61000-4-5 surge events on 5V power rails. 9.2V clamping at 9.1A peak. +/-30kV contact ESD rating. SOD-123FL flat lead for low-profile assembly.

A silicon avalanche diode designed to conduct heavily above 5.0V breakdown. When the protected line voltage exceeds VBR, the TVS avalanches and clamps the transient. The 200W peak pulse power rating (8/20us waveform) determines the maximum surge energy the device can absorb. Unidirectional: clamps positive transients above VBR and negative transients at the forward diode drop (~0.7V).
