Product Description

SMBJ20CA TVS Diode - Nanosecond response, building a safety barrier for precision circuits！
It is an industrial protection expert that can instantly absorb surge voltages up to 20V. With precise voltage clamping and ultra-low leakage current characteristics, it ensures that your electronic system is as stable as a rock under sudden voltage shocks. Widely used in communication base stations, power modules or industrial automation equipment.

Main Technical Parameters

  • Working voltage: 20V
  • Breakdown voltage: 22.2V-24.5V
  • Peak pulse current: up to 18.6A (8/20μs waveform)
  • Maximum clamping voltage: 32.4V
  • 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

SMBJ20CA uses silicon avalanche technology. When a transient pulse exceeding its breakdown voltage appears in the circuit, the device will quickly change from a high impedance state to a low impedance state, shunting the overvoltage energy to the ground. The bidirectional model can suppress transient voltages in both positive and negative directions, while the unidirectional model can only suppress transients in one direction.

Typical Applications

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