TVS-Diodes are built with a variety of features and specifications in order to provide ESD protection for various applications. The MXLP6KE20A is one such TVS-Diode device, designed to provide ESD protection using a combination of low capacitance and low ESD leakage current.

The MXLP6KE20A device is an ultra low capacitance ESD protection device with an adjustable trigger voltage and an ESD discharge resistor. This device is designed to protect sensitive electronic equipment from electrostatic discharge events. It is typically used in LCD panels, touch panels, and wireless modules to reduce system damage from ESD strikes.

The maximum capability of this device is 20A in the low capacitance configuration for up to 8 kV ESD protection. The on-resistance of the device is below 0.2Ω at maximum current ratings. The device is designed to minimize capacitance by actively switching on when ESD events occur and then immediately switching off when the event is over. This allows for protection of the most sensitive components against static electricity.

The working principle of the MXLP6KE20A is based on the integrated electrostatic discharge protection circuit (ESDPC). The circuit consists of a low-resistance MOSFET switch and an adjustable resistor to control the triggering voltage. When an ESD event occurs, the voltage across the ESDPC increases, triggering the switch and allowing the device to actively and automatically discharge the electrostatic charge to the ground. The trigger voltage is adjustable from 3V to 24V. Once the ESD event is over, the ESDPC immediately switches off, disconnecting the ground from the ESDPC. This prevents current leakage and avoids damage to sensitive components.

The device is designed to work in a wide temperature range from -55°C to +125°C. It is also capable of operating at a wide range of supply voltages from 2.7V to 5.5V. The package size of the device is small enough to allow it to be embedded in existing PCBs. This makes the MXLP6KE20A ideal for use in handheld and portable applications, such as cell phones, tablets, and other electronic devices.

The MXLP6KE20A is a versatile and cost-effective TVS-diode solution for ESD protection. It offers excellent protection and performance in a wide range of applications. With its low capacitance, adjustable trigger voltage, and wide temperature range, it is the perfect choice for providing robust ESD protection in sensitive electronic equipment.
