Introduction

TVS - Diodes are electronic components used to limit or suppress over-voltages. They are also known as Surge Suppression Diodes, Transient Voltage Suppression Diodes, or Transient Voltage Suppression Devices. The SMCG13CAHE3/9AT is a type of TVS - Diode specifically developed for industrial and automotive applications. It is a unidirectional diode that provides surges and over-voltage protection for a wide range of operating currents, voltages, and power circuits.

Application Field

SMCG13CAHE3/9AT is designed to provide protection in industrial and automotive applications where over-voltage can damage sensitive electronic components. Examples include: industrial, military and aerospace systems, automotive and motive power systems, communication systems, lightning and surge protection devices, high voltage protection, power supply circuits, and switch-mode power converters.SMCG13CAHE3/9AT is particularly suitable for automotive applications, such as those found in car doors, windows, headlights, wipers, and other applications where protection against high voltage and surges is needed. In addition, the device is also suitable for applications such as motors, motor controllers, relays and flyback converters.

Working Principle

The SMCG13CAHE3/9AT is based on the principle of avalanche breakdown: when the voltage rises above its rated value, the depletion region of the diode expands, causing a large amount of current to flow through the diode. This current, known as an avalanche current, is limited by the diode\'s protection element.The protection element is designed to limit the voltage and current of the surge or over-voltage, protecting the circuit from damage. If the surge or over-voltage does not exceed the rated value, the diode will continue to operate normally without any problem.

Conclusion

SMCG13CAHE3/9AT is a type of TVS - Diode that is designed to limit or suppress over-voltages in industrial and automotive applications. It is based on the principle of avalanche breakdown, and its protection element limits the voltage and current of the surge or over-voltage, protecting the circuit from damage. SMCG13CAHE3/9AT is particularly suitable for automotive applications such as those found in car doors, windows, headlights, wipers, and other applications where over-voltage protection is required.
