1PMT5.0AT1 Circuit Protection

TVS-Diodes, otherwise known as transient voltage suppressors (TVS), are electronic protection devices used to protect sensitive electronic components from transients in the power supply. By dissipating, or “shunting”, the excessive voltage away from a circuit, TVS-Diodes keep the voltage levels within the safe range before it reaches vulnerable components of the system. TVS-Diodes are used as a safeguard in electrical and electronics systems, ensuring that the connected equipment is always within safe operational voltage limits.

The PMT5.0AT1 TVS-Diode series from Littelfuse is designed to protect sensitive electronics from overvoltage transients. The TVS-Diodes provide an effective and efficient means of safeguarding sensitive equipment from transient spikes in the power line. The PMT5.0AT1 series has a peak pulse power rating of 400 watts, and a peak pulse current rating of 5.0A with an operating voltage of 5.0V. With its surface mount construction and low profile design, the PMT5.0AT1 series is ideal for use in portable electronics such as laptops, cellular phones, and other electronic devices.

The PMT5.0AT1 TVS-Diode works on the principle of avalanche breakdown. When the anode-cathode voltage exceeds the device\'s breakdown voltage, a sudden rush of current occurs, which is called “avalanche breakdown”. The avalanche breakdown currents increase rapidly and clamps the voltage to a safe operating level, thereby providing protection to the other system components. As such, the PMT5.0AT1 TVS-Diode provides surge current protection as well as voltage clamping to components connected to it.

The PMT5.0AT1 TVS-Diode has applications in AC and DC power supplies, laptop, desktop, and server power supplies, automotive and automotive battery power supplies, telecom equipment power supplies, industrial motor drives, LED lighting, and other consumer electronic devices. It can be used to protect against electrical transients which can occur due to power spikes, electrostatic discharge, magnetic induction, and more. The device is designed to handle both high-voltage and high-current transients and is suitable for use in high-power switching systems.

The PMT5.0AT1 TVS-Diode provides excellent protection to sensitive components from voltage transients. It is a robust, durable, and reliable device that effectively helps to reduce system downtime and ensure the safe and efficient operation of electrical and electronics systems.
