P4SMA480A - Transient Voltage Suppression Diodes

Download the P4SMA480A datasheet PDF. This datasheet also covers the P4SMA6.8A variant, as both devices belong to the same transient voltage suppression diodes family and are provided as variant models within a single manufacturer datasheet.

General Description

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

Key Features

  • 400W peak pulse power.
  • 260oC/40sec change to capability at 10/1000µs 260oC/30sec waveform, repetition rate (duty cycles):0.01%.
  • VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25))(αT:Temperature.
  • Excellent clamping capability Coefficient, typical value is.
  • Typical IR less than 1μA when 0.1%) VBR min>12V.
  • Surface mount footprint for compact PCB layout.
  • Low profile package.
  • UL Recognized epoxy meeting flammability classification V-0 change to Plastic packag.
