TVS318 Circuit Protection

TVS - Diodes

TVS, short for Transient Voltage Suppressor, is an electrical device designed to protect other electrical components by clamping the voltage to a specific level when a surge occurs. A TVS diode is a type of diode specifically designed as a transient voltage suppressor which utilizes zinc oxide as the core structure.

The TVS318 is a fast transient voltage suppressor specifically designed for automotive applications. It is capable of suppressing surge voltages up to 21V, and is designed to comply with the OBD II, CAN and J1113 automotive standards. This diode is perfectly suited for the protection requirements of ECUs, radio receivers and other electronic components.

The way TVS diodes work is quite simple. These diodes are designed to provide a low impedance path for any high voltage surge, similar to a fuse. When a voltage surpasses the breakdown voltage of the TVS, the diode will be heavily biased in the forward direction and should remain in conduction until the voltage returns below the breakdown voltage.

Apart from its usage in automotive applications, TVS318 diodes can also be used for lightning protection, power supply protection, regulation of system voltage, and other surge protection applications.

The TVS318 diode offers several advantages over its predecessors:

• High peak power capability
• High peak surge current capability
• Excellent thermal performance
• High reliability

The most important thing to know about these diodes is that their performance is strongly dependent on the design and size of the diode. It is also important to choose the correct diode for the application. For instance, if the surge needs to be clamped to more than 21V, then a diode with higher clamping voltage should be used.

In conclusion, the TVS318 diode is an innovative and reliable solution for the protection of automotive components against surge voltages. This diode is capable of withstanding high surge voltages up to 21V, and offers the additional advantages of high peak power capability, excellent thermal performance, and high reliability.
