Product Description

SMBJ48CA is a high reliability transient voltage suppression diode with 600W peak pulse power handling capability,48V bidirectional protection, fast response speed, and precise clamping voltage.It is an ideal circuit protection solution for industrial automation,power modules,and communication equipment.

Main Technical Parameters

  • Working voltage:48V
  • Breakdown voltage:53.3V-58.9V
  • Peak pulse current: up to 7.8A (8/20μs waveform)
  • Maximum clamping voltage:77.4V
  • Power level: 600W
  • Polarity: Bidirectional

Features and Advantages

  • Low profile package
  • Ideal for automated placement
  • 600 Watt peak pulse power capability with a 10/1000μs waveform
  • For surface mounted applicatons to optimize board space
  • Excellent clamping capability
  • Very fast response time
  • Low incremental surge resistance

Working Principle

  • Normal state
    When the circuit voltage is lower than the reverse cutoff voltage, the device is in high impedance state (cutoff state), which has almost no effect on the circuit.
  • Transient voltage trigger
    When the voltage exceeds the breakdown voltage, the device quickly enters the low impedance state (avalanche breakdown), discharges the excess energy to the ground through itself, and clamps the voltage below the clamping voltage.

Typical Applications

  • Power supply protection
  • Automotive application
  • Industrial application
  • Power management
