SA64A-E3/73 is a type of TVS – Diode, which is also known as Transient Voltage Suppression (TVS) Diode. This type of diode is used to provide protection against overvoltage conditions, such as electrostatic discharge (ESD) and electrical overstress (EOS), by clamping or limiting the transient voltage surges typically created by these events.

A TVS diode is a nonlinear unidirectional device that protects circuits from electrical transients. It acts as a voltage regulator, absorbing and then clamping transient voltages back to a safe voltage level. TVS diodes are constructed with a uniform, symmetrical PN junction and are designed to turn into a low resistance state when a critical voltage is reached.

The SA64A-E3/73 series TVS diodes are available in a wide range of breakover voltages and several power dissipation levels. They are unidirectional devices with a high level of ESD protection. This device is designed to protect sensitive electronic circuits against electrostatic discharge (ESD), power transients and other overvoltage events.

The SA64A-E3/73 TVS diodes are specifically designed to protect very sensitive automotive applications, such as airbag systems. They also work well for protection against lightning surges in telecommunications and in many other applications. The typical maximum peak pulse power capability is 2.4kW, making them ideal for environments where low capacitance and low clamping voltages are vital.

In terms of working principle, the SA64A-E3/73 series TVS diodes are designed to be triggered when a specified voltage is exceeded, such as that created by an ESD pulse. When this occurs, the device will conduct a current, limiting and dissipating the energy produced by the pulse. The current will flow until the voltage returns to within the normal operating level. The voltage at which it is triggered is referred to as the breakdown voltage.

The SA64A-E3/73 series TVS diodes are well suited for many applications in the automotive industry, providing excellent levels of ESD, surge and final protection. They are also robust, reliable and have a low power dissipation. These characteristics make them suitable for protecting all types of sensitive automotive electronics from the harmful effects of electrical surges.
