PESD24VS2UAT,215 Circuit Protection

TVS - Diodes

Transient Voltage Suppression (TVS) diodes are solid-state semiconductor devices used for surge protection and ESD (electrostatic discharge) prevention. The PESD24VS2UAT,215 is a diode from this class of devices that is widely used in the electronics industry. This article looks at the application field and working principle of this particular diode.

Application Field

The PESD24VS2UAT,215 representation is a bi-directional diode with ultra low capacitance, which allows it to be used with higher frequency applications than other types of diodes. These are commonly employed in areas where electrical surges threaten to damage delicate electrical components, such as in automotive electronics, consumer electronics, and data processing. The device is designed with an integrated guard-ring structure that provides enhanced protection against transient voltage surges. The PESD24VS2UAT,215 also ensures safe and reliable operation of various automotive electrical systems.

Working Principle

A TVS diode is composed of a junction between a p-type semiconductor and an n-type semiconductor. When a current flows in one direction through the junction, the diode will only allow a certain amount of voltage to pass; this is its clamping voltage. If the current then flows in the opposite direction, the amount of voltage allowed to pass will be different and the diode’s capacity to suppress the voltage surge will be reduced. The voltage at which the diode will start to clamp will depend on the current flowing through it and the temperature of the diode.

The PESD24VS2UAT,215 has a breakdown voltage of 24 volts and a maximum peak pulse current of 1 A, and is capable of handling voltage spikes up to 10A for periods up to 10 ns. The device also features integrated reverse-polarity protection, allowing it to handle negative voltage transients. It is also designed to handle transients up to 1000 volts in the reverse direction.

Conclusion

The PESD24VS2UAT,215 is a reliable, robust TVS diode designed to provide surge protection and ESD prevention for a wide range of applications. The integrated guard-ring structure and reverse-polarity protection allow the device to handle high voltages and voltage transients. The device is capable of handling voltage spikes up to 10A and transients up to 1000 volts in the reverse direction, making it the ideal choice for applications that require a high degree of electrical protection.
