TVS-Diodes are a particular type of semiconductor that are designed for providing surge protection from overvoltages in electrical systems. The 1PMT22AT1 is a unidirectional transient-voltage suppressor (TVS) diode specifically designed to protect sensitive circuitry or components from overvoltages over a wide variety of conditions, including voltage spikes, surges, and transients that can occur in both AC and DC circuits. The 1PMT22AT1 is capable of handling an incoming pulse of up to 24V and a power dissipation of 5W.

Application Field

The 1PMT22AT1 is mainly intended for use in the automotive industry for overvoltage and surge protection of automotive systems against electromagnetic interference (EMI). This could include protecting the radio, diagnosis and testing devices, displays, and other electronic components. In addition, this device is suitable for use in automotive, industrial, and consumer applications.

Working Principle

The 1PMT22AT1 is a semiconductor device composed of a diode connected to a thyristor and a Zener diode. The thyristor is set to operate at high voltage, setting up an electrostatic force and flow of electrons between the anode and the cathode. When an overvoltage rises above the Zener diode voltage, the thyristor opens up and voltage will be diverted away from the protected circuitry and components.

The thyristor acts as a switch, allowing a certain amount of energy to pass through and the Zener diode helps to ensure that the maximum voltage on the protected circuit does not exceed the rated maximum of the device. Once the voltage has been diverted, the thyristor will reset, prompting the device to reset and it will be ready for the next overvoltage. This mechanism allows the 1PMT22AT1 to protect against both continuous and one-time overvoltages.

The 1PMT22AT1 is designed to be highly reliable due to its high surge capability, low leakage current, and fast turn-on and turn-off time. Furthermore, its small size makes it suitable for use in a variety of tight spaces.

Conclusion

The 1PMT22AT1 is an effective and reliable transient-voltage suppressor (TVS) diode designed to protect sensitive circuitry or components from overvoltages over a wide variety of conditions. It is mainly intended for use in the automotive industry for overvoltage and surge protection from electromagnetic interference (EMI). It is a semiconductor device composed of a diode connected to a thyristor and a Zener diode and is capable of handling an incoming pulse of up to 24V and a power dissipation of 5W.
