TVS - Diodes

A Transient Voltage Suppressor (TVS) diode is a device steadily employed in the field of electrical HV (high voltage) protection. It is constantly used in areas such as electronic equipment, medical devices, and automotive industry, to protect against surges, spikes, and transients overvoltage. The idea relies on current limitation when an overvoltage is applied to the clamped diode. The mechanism of this reverse current is what makes this diode become an ideal choice when it comes to protection from high voltage.

TV02W101B-HF application field and working principle

The TV02W101B-HF is a high voltage diode from the TVS family. After being inserted in a circuit, it is capable of providing a low impedance path to ground for transients and trips. It is typically used in such areas as AC/DC power protection and security cameras. Additionally, it may be inserted in places where space is at a premium, allowing designers to reduce cost and maintain a high-quality product.

The TV02W101B-HF provides a breakdown voltage of 200V as well as a maximum peak pulse surge current of 100A. Its low reverse standing leakage current enables a low strain and low energy consumption when priming the diode. The device can dissipate up to 80W of energy, reducing diode strain to a minimum. It has an available part number in a 3-pin, single row, tape and reel configuration.

The principle on which the TV02W101B-HF works is by providing reverse current flow, which is then directed to the supply line ground or to an existing ground potential. This is a commonly known technique for clamping higher voltage. As the reverse currentPath is established, the break voltage is reached, thereby attracting the inrush current. Then, the power of the inrush current is changed to energy that dissipates along the device, hence avoiding short circuit.

The greatest challenge when it comes to using TVS diodes in their applications is to maintain a steady and accurate breakdown voltage. Regarding this, TV02W101B-HF is a great device as it is extremely stable due to its excellent reverse leakage characteristics, configuration, and test procedures.

To conclude, the TV02W101B-HF is an efficient device employed in many fields and applications and is greatly known for its ability to provide a low impedance path for transients and trips in order to protect the device from adverse electrical overvoltage and EMI/RFI emissions. Additionally, it is capable of dissipating up to 80W of energy when properly used and configured.
