TVS - Diodes: MPLAD30KP400AE3/TR Application Field and Working Principle

TVS (Transient Voltage Suppressors) diodes are a form of voltage-sensitive element that is designed to protect integrated circuits (ICs) from transient voltage overshoots (including electrostatic discharge – ESD). TVS diodes are designed to take the voltage overshoot and clamp it to a safe voltage level in order to protect the electronic components from damage. The MPLAD30KP400AE3/TR diode from ON Semiconductor is one example of a TVS diode available on the market.

What is MPLAD30KP400AE3/TR?

The MPLAD30KP400AE3/TR diode is a low-capacitance, dual-channel ESD protection device embedded in a small, surface-mount package that is designed to protect high-speed data interfaces such as HDMI, DisplayPort, and USB3.0. It offers a wide operating range from -3 to +18V, and its lower capacitance ratings of 0.7pF make it suitable for a variety of high-speed applications. The diode also offers low leakage current and a low reverse current rating of 1μA.

MPLAD30KP400AE3/TR Application Fields

The MPLAD30KP400AE3/TR diode is rated for up to 30 kilovolts and is a suitable surge-protection device for many electronic components. It has been specifically designed to protect high-speed signals from ESD damage, but it can also be used to protect power lines as well. Additionally, it can be used in applications requiring high levels of EMI/RFI noise suppression, such as RFID and automotive applications.

MPLAD30KP400AE3/TR Working Principle

The MPLAD30KP400AE3/TR diode works by clipping the voltage overshoot to a safe level before it can do any damage to the connected components. The diode consists of two PN-junction diodes connected in series, with the anode of one diode connected to the cathode of the other. When the input voltage rises above the diode\'s breakdown voltage, current is allowed to pass through the series connection and the voltage is clamped to a safe level.

Additionally, the MPLAD30KP400AE3/TR features a reverse-breakdown voltage rating of 18V, which allows it to be used in a wide range of automotive applications and makes it suitable for applications with high levels of EMI/RFI noise. The diode also has an integrated ESD protection element that can be used to protect high-speed data lines such as HDMI, DisplayPort, and USB3.0.

Conclusion

The MPLAD30KP400AE3/TR diode is a low-capacitance ESD protection device designed to protect high-speed interfaces such as HDMI, DisplayPort, and USB3.0. It offers a wide operating range from -3 to +18V, and its lower capacitance ratings of 0.7pF provide superior protection against electrostatic discharge. Additionally, it can be used in a variety of applications requiring high levels of EMI/RFI noise suppression, such as RFID and automotive applications. The diode also has a reverse-breakdown voltage rating of 18V, making it suitable for automotive applications.
