Product Description

This device is a high-performance,unidirectional TVS diode designed as a direct replacement for the industry-standard SMAJ36A.It provides robust protection against electrostatic discharge (ESD),electrical fast transients (EFT),and surge voltages induced by lightning or other transient events.
Fully compatible with SMAJ36A diode from leading manufacturers,our equivalent diode matches the same electrical specifications and package dimensions while offering cost efficiency and reliable supply chain stability.

Main Technical Parameters

  • Working voltage:36V
  • Breakdown voltage:40V-44.2V
  • Peak pulse current: up to 6.9A (8/20μs waveform)
  • Maximum clamping voltage:58.1V
  • 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

  • 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

  • DC power supply protection
  • I/O interface and data lines
  • Automotive and industrial electronics
  • Telecom and networking equipment
  • Surge protection for sensors and controllers
