TVS – Diodes are electronic components that limit the surge voltage and current. They are used in the protection of lightning strikes, electrostatic discharge, and other high voltage or inductive transients. A TVS diode, also known as a Transient Voltage Suppressor, is designed to limit the voltage within an electrical circuit. It is primarily used as a protection device to protect sensitive components such as microcontrollers, logic gates, voltage regulators, power switches, and microprocessors from high voltage transients in the environment or from transient voltages on a power supply line.

The TPC24HM3/86A is a common TVS diode which provides ESD (electro static discharge) protection on one line and working voltage up to 600Vrms in a compact package. The TPC24HM3/86A is a two terminal, diode-connected, high-speed, low-capacitance transient voltage suppressor ideal for ESD, lightning, and inductive spike protection. It features high surge current capability, low breakdown voltage, and excellent clamping performance.

The TPC24HM3/86A device is mainly used in communication and data transfer applications, factory automation, consumer electronics, defense and aerospace, medical devices, automotive, solar energy, and electronic lighting. It is applicable in high-speed data interfaces (Ethernet, POE, USB3), battery-powered systems, automotive/transportation systems, industrial, lighting, LED applications, and general industrial applications.

The TPC24HM3/86A has a low clamping voltage, allowing it to be used in a variety of applications. Its low clamping voltage also provides excellent protection for data and communication lines, protecting the sensitive components from any transient voltages that may exist in the environment. The component also has very low capacitive loading which helps avoid noise reactions from the power supply.

The working principle of the component is based on Poole-Frenkel emission. TPC24HM3/86A can significantly reduce the power dissipation caused by the voltage spike events on one line using its clamping voltage while providing an imbalance tolerance. When the voltage across the component exceeds the breakdown voltage, the gate region voltage rises and carriers are injected into the channel region, which results in a reversible diode-like current. This current creates a voltage drop across the gate and channel which helps clamp the voltage. This change is reversible and will act to protect the circuit and its components.

Overall, the TPC24HM3/86A is a great choice for many TVS applications, offering reliable protection and excellent capacitive loading performance in a very small package. It provides excellent ESD protection, lightning protection, and inductive spike protection, and can help protect sensitive components from transient voltages. The low clamping voltage of the TPC24HM3/86A also makes it a great choice for any application where low capacitive loading is a requirement.
