TVS – Diodes

TVS – Diodes are an array of unique semiconductor devices that provide advanced protection against electrical overstress and transient voltage surges caused by electrostatic discharge (ESD). They can be used in various consumer and industrial application, such as automotive and other transportation industries, telecommunications, and medical equipment. The P4KE9.1AHR1G series is a great example of a surge protected device, with its strong protection capabilities against ESD and transient voltage surges.

Application Field

The P4KE9.1AHR1G series is ideal for preventing system damage caused by overvoltage transients due to industrial or home uses. It\'ll act as a clamp for voltage spikes, and will absorb and divert the damaging surge current away from processors, memory, ICs, and other sensitive components.

Apart from computers and consumer products, the P4KE9.1AHR1G TVS diode is also widely used in automotive and other transportation industries, telecommunications, and medical equipment. In these cases, the diode can protect the sensitive components inside from voltage spikes, power surges, and other electrostatic discharge-related events.

Working Principle

The working principle of the P4KE9.1AHR1G TVS diode is simply that it absorbs and diverts the surge current away from sensitive components. When the diode is exposed to high electric fields or high power transients, it will conduct and divert the electrostatic charge to ground, before it can reach the sensitive components and cause damage.

To ensure the effective protection against voltage transients, the diode must be placed as close to the sensitive component as possible. This is because the further away the diode is placed from the source, the greater the likelihood of the surge current causing damage to the component. The P4KE9.1AHR1G series of diodes has a relatively fast response time, which helps to ensure that even high surges out of specifications will be clamped quickly and effectively.

Conclusion

The P4KE9.1AHR1G series of TVS diodes are widely used as surge-protecting components in consumer, automotive, telecommunications, and medical industries. As such, they are a powerful tool for helping to protect valuable systems and components against electrical overstress and transient voltage surges. Its identification as a TVS diode is based on its ability to absorb and divert electrostatic charge to ground, thus helping to ensure that the equipment and components remain safe and ready to use.
