• MXLSMLG45CA Application Field and Working Principle

  A Metal Oxide Semiconductor with Limitied Groove and typically Higher Clamping Area (MXLSMLG45CA) is a type of transient voltage suppressor diode (TVS). It is used to safeguard electrical systems-including microprocessors, data systems, communication systems, and other electronic circuits-from damage due to electrical overstress (EOS) such as electrical transients, surge currents, electrostatic discharges (ESD), and overvoltage.

  The MXLSMLG45CA application field mainly includes:

  • Information and Communications Technology
  • Consumer Electronics
  • Automotive Electronics
  • Industrial Control
  • Medical Electronics
  • Lighting Control
  • Home Security Systems
  • Solar Power Systems

  The working principle of an MXLSMLG45CA is based on a numberof physical phenomena. When exposed to electrical overstress, the excess current is absorbed and redistributed to the electrodes. This absorption is facilitated by the breakdown of the junction. In addition, the electrical field created by the voltage changes creates forces that are redistributed to the electrodes. This situation enables the MXLSMLG45CA to reach its best state quickly and limit any transient current.

  When a voltage is applied across the MXLSMLG45CA, it acts as an electronic fuse and does not conduct any current until a predetermined value is exceeded. At this point, the diode redirects the excess current and utilizes its own energy to control the over-voltage. Because of this, these diodes are highly efficient, durable and have low let-through voltages.

  The MXLSMLG45CA is a two-terminal, surface mount protection diode with a voltage range of 6 to 45 V and a reverse stand-off voltage range of 5.5 to 41 V.The diode provides excellent ESD protection for sensitive components and systems-up to 4 kV HBM and 8 kV CDM on all combinations. The device also offers superior surge current capability – up to 6.5 A, 8/20 μs pulse – and protects against high power low frequency noise.

  In all, the MXLSMLG45CA provides a powerful protection solution for any electrical system. By utilizing it, manufacturers and engineers can ensure their components and networks are protected against EOS events.
