Transient Voltage Suppression (TVS) diodes are an important component of many electronic circuits, protecting circuits from high voltage transients that could otherwise damage them. The SMS24CT1G is a TVS diode designed to protect circuits from electrostatic discharges (ESD), common in consumer electronics such as smartphones. This diode boasts a wide operating voltage range, low reverse leakage current, and fast response time, making it a suitable choice for many consumer electronics designs. In this article we will look at the application field of the SMS24CT1G, and its working principle.

Application Field

The SMS24CT1G is a unidirectional TVS diode designed to protect circuits from transient overvoltages. These transients can occur due to a variety of sources, including electrostatic discharges (ESDs), which are common occurrences in consumer electronics. The SMS24CT1G is designed to protect circuits from such transients, and is suitable for applications in mobile phones, automotive electronic systems, consumer electronics, computer peripherals, and more.

The SMS24CT1G is designed to operate in a wide range of voltages, from 2.4 V to 24 V, making it suitable for a wide range of applications. It also boasts a low reverse leakage current of less than 1 µA at 25 V, making it suitable for circuits with low power consumption. Additionally, it has a fast response time of less than 1 ns, making it suitable for applications with high speed data transmission.

Working Principle

The SMS24CT1G is a unidirectional TVS diode, meaning it allows current to flow in one direction only. When a transient voltage, such as an electrostatic discharge (ESD) occurs, the SMS24CT1G acts as a shunt for the current, diverting it away from the protected circuit. The maximum allowable current that the SMS24CT1G can dissipate depends on the power rating of the diode and the voltage of the transient. The diode has a breakdown voltage of 24 V, meaning that it can dissipate up to this voltage without damaging the protected circuit. Beyond this voltage, the diode will conduct current and dissipate the energy as heat.

The SMS24CT1G has a fast response time of less than 1 ns, meaning that it can respond quickly to transient events, protecting the circuit in a timely manner. It also has low capacitance and inductance, which helps to limit electromagnetic interference (EMI) and reduce the risk of data errors. Additionally, it has a low reverse leakage current, making it suitable for circuits with low power consumption.

The SMS24CT1G is a versatile TVS diode, suitable for protecting against a variety of transient events in a wide range of applications. Its wide operating voltage range, fast response time, low reverse leakage current, and low capacitance and inductance, make it suitable for many consumer electronics designs. This makes the SMS24CT1G an ideal choice for protecting circuits from electrostatic discharges, common in consumer electronics.
