TVS - Diodes

The TV04A251JB-HF (Transient Voltage Suppressor) is a type of diode designed for the protection of sensitive electronic components from voltage spikes or surges, which can potentially destroy the components, and cause them to malfunction. This TVS is designed to not only protect the delicate components, but also to minimize unwanted current flow, and ensure a reliable operation of the protected device.

Application Field

TV04A251JB-HF TVS Diodes are most commonly used in power septa, power supplies, telecommunications equipment, and commercial audio/video products, in order to protect components from voltage surges or spikes. These diodes are specifically designed for higher power pulses, and can handle power spikes of up to 150 watts.TV04A251JB-HF TVS Diodes are also used in automotive applications. These diodes feature a low capacitance, and a wide operating voltage range, making them highly suitable for use in the automotive industry. In particular, these devices are used to protect delicate components, such as engine control modules, radios, and electric motor winding systems, from voltage surges, due to their ability to quickly clamp to higher power pulses.

Working Principle

TV04A251JB-HF TVS Diodes operate on the principle of avalanche breakdown. Whenever a voltage spike exceeds the breakdown voltage of the TVS, the diode will switch to a low-resistance state, allowing a sudden influx of current to flow through it. This current surge will then dissipate into the ground before it can do any damage to the protected device.When the voltage spike is gone, the TVS will quickly switch back to its high-resistance state, stopping any further current from flowing through it. This process is known as “clamping” and is vital for protecting delicate components from voltage spikes.TV04A251JB-HF TVS Diodes are designed to maximize their clamping efficiency, while also minimizing their current leakage. This is done by using a special combination of semiconductor materials and a special geometry. Additionally, the components are designed to withstand extreme temperatures, shocks, and vibration.

Conclusion

TV04A251JB-HF TVS Diodes are a type of diode designed for protecting sensitive electronic components from voltage spikes. They are commonly used in power supplies, telecommunications equipment, automotive applications, and commercial audio/video products. The working principle of these devices is based on avalanche breakdown, which quickly clamps to higher power pulses. Additionally, these components are designed to withstand extreme temperatures, shocks, and vibration to ensure a reliable operation of the protected device.
