TVS - Diodes

TVS or ‘Transient Voltage Suppressor’ diodes are special components that help protect sensitive circuits from voltage surges from external sources, such as lightning, electrostatic discharges from handling, or surges produced by machinery. They help maintain voltage levels within a safe range by limiting and dissipating voltage excesses. TVS diodes are used in a wide range of applications.

JANTXV1N6125AUS is a specific type of TVS diode. It is suitable for protection against voltage spikes up to 15 KV, with a maximum peak current rating of 4 A. It is also a unidirectional, avalanche diode with a lead frame structure.

The JANTXV1N6125AUS is a versatile component. It is capable of operating from -65℃ up to +150℃, with a breakdown voltage range of 17 to 21 volts. It is also polarized, meaning the peak current is split between the anode and the cathode, allowing it to dissipate more power.

The main applications for JANTXV1N6125AUS are for protection against surge related power losses in electronic equipment, such as in communication systems, computers, LED drivers, power supplies, audio equipment, and many others. It is also suitable for automotive applications, where transients are caused by electrical disturbances from the environment.

In terms of its working principle, the JANTXV1N6125AUS is a Varistor diode, meaning it is able to provide a reverse voltage when a transient voltage is applied. As the voltage is increased, the junction area of the Varistor diode gets filled with electrons, causing an avalanche breakdown. This effectively limits the circuit’s voltage and helps protect against surges.

In conclusion, the JANTXV1N6125AUS is a specialized type of TVS diode, capable of providing surge protection for a variety of electronic systems and devices. Its main applications are in communication systems, audio equipment, computer accessories, LED drivers, and many more. Its working principle is based on a varistor diode, which absorbs and dissipates excess voltage when it is applied, helping to maintain voltage levels within a safe range.
