Product Description

SMAJ15CA is a high-performance bidirectional transient voltage suppression diode with a compact SMA package and 400W peak pulse power. It can respond quickly when voltage transients occur, effectively protecting electronic equipment from interference such as lightning strikes and inductive load switching.It is suitable for a variety of application scenarios such as communications, power supplies, and electronic control systems.

Main Technical Parameters

  • Working voltage: 15V
  • Breakdown voltage: 16.7V-18.5V
  • Peak pulse current: up to 16.4A (8/20μs waveform)
  • Maximum clamping voltage: 24.4V
  • Power level: 400W
  • Polarity: bidirectional

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

SMAJ15CA 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
