The P4SMA series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Features & Benefits:

  • 400W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles): 0.01%
  • Excellent clamping capability
  • Typical IR less than 1μA when VBR min>12V
  • Surface mount footprint for compact PCB layout
  • Low profile package
  • Typical failure mode due to exceeding maximum ratings is a short circuit condition
  • Whisker test conducted based on Table 4a and 4c of JEDEC JESD201A
  • IEC 61000-4-2 ESD 30kV(Air), 30kV (Contact)
  • Built-in strain relief
  • Fast response time: typically less than 1.0ps from 0V to BV min
  • 260°C/40sec change to 260°C/30sec
  • VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25))(αT:Temperature Coefficient, typical value is 0.1%)
  • UL Recognized epoxy meeting flammability classification V-0 change to Plastic package is flammability rated V-0 per UL-94.
  • Meet MSL level1, per J-STD-020, LF maximum peak of 260°C
  • Matte tin, lead-free plated
  • Halogen-free and RoHS compliant
  • Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD-609A.01)

Applications:

TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
