200W Surface Mount Transient Voltage Suppressors in SMF (JEDEC SOD-123) Package

The SMF series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

SMF package is 50% smaller in footprint when compare to SMA package and delivering one of the lowest height profiles (1.1mm) in the industry.


  • Compatible with industrial standard package SOD-123
  • Low profile: maximum height of 1.1mm
  • For surface mounted applications to optimize board space
  • Typical failure mode is short from over-specified voltage or current
  • Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c.
  • IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact).
  • ESD protection of data lines in accordance with IEC 61000-4-2 (IEC801-2)
  • EFT protection of data lines in accordance with IEC 61000-4-4 (IEC801-4)
  • 200W peak pulse power capability at 10x1000µs waveform, repetition rate (duty cycle):0.01%
  • Low inductance, excellent clamping capability
  • Fast response time:typically less than 1.0ns from 0 Volts to VBR min
  • Built-in strain relief
  • Glass passivated junction
  • High temperature soldering: 260°C/40 seconds at terminals
  • Matte tin lead–free plated
  • Halogen free and RoHS compliant
