Description

The SMDJ90A-HRAT7 is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse. It is specifically designed to protect sensitive electronic equipment from high-energy transient events such as lightning strikes, inductive load switching, and electrostatic discharge (ESD). The device is packaged in a surface-mount SMDJ (DO-214AB) package, suitable for automated assembly processes.

Applications

  • Power supply protection
  • Industrial control systems
  • Telecom equipment
  • Automotive electronics
  • High-reliability applications

Features

  • Surface mount SMDJ (DO-214AB) package
  • Stand-off Voltage: 90V
  • Peak Pulse Power: 3000W (10/1000μs waveform)
  • Glass passivated junction
  • Excellent clamping capability
  • Low incremental surge resistance
  • High reliability
  • RoHS compliant

Benefits

  • Provides robust protection against high-energy transient events, enhancing the reliability and lifespan of electronic systems.
  • Surface mount package facilitates automated assembly.
  • Excellent clamping capability minimizes voltage overshoot during transient events.
  • High reliability ensures consistent performance in demanding applications.
  • Complies with industry environmental standards.

Detailed Specs

The SMDJ90A-HRAT7 is a unidirectional TVS diode with a stand-off voltage of 90V. The peak pulse power dissipation is rated at 3000W for a 10/1000μs waveform. The clamping voltage is designed to limit the voltage across the protected circuit to a safe level during a transient event. The operating temperature range is typically from -55°C to +150°C. The 'HRA' designation typically indicates a high-reliability automotive-grade component. It is vital to consult the manufacturer's datasheet for precise electrical characteristics, including the clamping voltage at specific test currents, reverse leakage current, forward voltage drop, and surge current capability. The datasheet also provides information on the device's capacitance and its ability to handle repetitive surge events.
