Product Description

In modern electronic systems, surge protection is an important part of ensuring safe and stable operation of circuits.SMAJ58A is a common transient voltage suppressor diode, which is widely used in various sensitive electronic devices to protect against transient overvoltage caused by lightning strikes, electrostatic discharge (ESD),switching operations,etc.

Main Technical Parameters

  • Working voltage: 58V
  • Breakdown voltage: 64.4V-71.2V
  • Peak pulse current: Up to 4.3A (8/20μs waveform)
  • Maximum clamping voltage: 93.6V
  • Power level: 400W
  • Polarity: Unidirectional

Features and Advantages

  • Low profile package
  • Ideal for automated placement
  • 400 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

SMAJ58A is in a high impedance state and is almost non-conductive under normal voltage. When the external transient voltage exceeds its breakdown voltage, it will immediately conduct and bypass the surge current to the ground, thereby protecting the subsequent circuit. It should be noted that it is unidirectional and is only applicable to DC circuits or signal lines with clear polarity.

Typical Applications

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