Product Description

The SMBJ5.0CA TVS diode is a surge protection device based on the avalanche breakdown principle, specifically designed to protect sensitive electronic circuits from ESD (electrostatic discharge), surges, and other transient voltage disturbances.When a transient pulse exceeding its breakdown voltage appears in the circuit, the TVS diode quickly switches from a high-impedance state to a low-impedance state, diverting the overvoltage energy to the ground.

Main Technical Parameters

  • Working voltage: 5.0V
  • Breakdown voltage: 6.4V-7.0V
  • Peak pulse current: up to 65.3A (8/20μs waveform)
  • Maximum clamping voltage: 9.2V
  • 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
