TVS (transient voltage suppressor) diodes are a relatively new type of device used to protect components from extreme and short-lived voltage fluctuations which can damage a circuits delicate components. The SA7.0CA is a unidirectional TVS diode, specifically designed for use in the automotive industry where it is used to protect components from large transients and spikes. It is ideal for applications such as circuit switches, electrical components, fuel systems, and brake systems.

The SA7.0CA utilizes a unique hybrid construction which utilizes both Zener and avalanche breakdown characteristics. This allows the device to be much more effective at suppressing and containing plasma formed during rapid current changes such as ESD (electrostatic discharge) events. The device can respond to large transients within nanoseconds.

The device works by:

• Clamping the transient current at its maximum level with its Zener junction;
• Passing the energy from the transient current through the junction and to the rest of the circuit;
• Clamping the transient voltage using the avalanche breakdown capabilities.

The SA7.0CA has built-in features which allow it to handle more than just the transient current and voltage. It can also help to reduce power dissipation, influence the shape and duration of the transient, and improve the life of the device. Additionally, the device can be used in series or parallel configurations depending on the application.

The SA7.0CA is designed specifically for automotive applications. It has a low profile, which makes it suitable for use in cramped conditions, such as under the dashboard of a car. It is also able to handle temperatures of up to 175°C, making it suitable for use in hot environments. The device is also RoHS compliant and is suitable for use in International Space Station applications.

The SA7.0CA has been designed to be a reliable and robust solution to the problems posed by transient events in automotive applications. Its unique hybrid design allows it to be extremely effective at clamping the transient current and voltage. It can also provide protection from heat, ESD events, and reduce power dissipation. Its small size and RoHS compliance make it ideal for use in tight or high temperature environments. The device has proven itself to be a reliable and robust solution in countless automotive applications and is sure to be a valuable addition to any automotive circuit.
