TVS (transient voltage suppression) diodes are commonly used in medium-voltage applications, ranging from 5-1000V. This includes the SA14CHE3/73, a unidirectional TVS diode specifically designed for use in automotive applications. In this article, we’ll discuss the application fields and working principle of the SA14CHE3/73.

The SA14CHE3/73 is designed with a low power metastable NPN transistor, allowing it to handle high surge currents up to 150A. It is also designed with an ultra-fast breakdown, providing 5ns response time for high current protection. This makes it an ideal choice for automotive applications such as ignition coils, pre-charge circuits, and electric starter motors. The SA14CHE3/73 can also be used in industrial applications such as power supplies, motors, and other high current circuitry.

The working principle of the SA14CHE3/73 is based on its non-linear resistance behavior. The diode sets a threshold voltage, and any incoming voltage exceeding that threshold triggers the breakdown. This quickly reduces the current to a safe level, protecting the device from damage. The diode features a low capacitance, which helps keep the power loss to a minimum.

The SA14CHE3/73 is designed with a wide range of features for improved performance. It has a low on-state voltage drop, which helps reduce power dissipation. The diode also comes with a reverse polarity protection, allowing it to be used in either straight or flip-flop configurations. The diode is guaranteed to last up to 1,000 hours, making it highly reliable in harsh environments. The diode is also UL certified, which ensures that it meets the highest safety standards.

The SA14CHE3/73 is an excellent choice for a wide range of applications. It is designed to provide superior performance in automotive and industrial applications and can handle high surge currents up to 150A. The diode also comes with a range of features, including a low on-state voltage drop and reverse polarity protection. Additionally, the diode is UL certified and guaranteed to last up to 1,000 hours, making it a highly reliable and safe choice.
