1. Introduction: MXLPLAD18KP75AE3 is a unidirectional bidirectional transient voltage protection diode, which belongs to the TVS - Diodes category. It is a surface-mount diode that is typically used in transient voltage suppression applications like cell phones, PDAs and other handheld portable equipment. It is designed to be resilient to fast, high-voltage surges, providing excellent protection against overvoltage on data signal lines.
2. Design: The MXLPLAD18KP75AE3 is designed for bidirectional simultaneous protection of data lines. It provides unidirectional voltage protection from up to 18KP75A volts to ground, withstanding voltage up to 18KP75A in either positive or negative direction. The operating temperature range is from -55 to +125 degrees Celsius, and it is designed for surface-mounting. It is offered in an 8-pin SOP package. The forward voltage drop is minimum, making it suitable for data signal line protection.
3. Applications: The MXLPLAD18KP75AE3 is primarily targeted at GSM mobile phones, PDAs, personal computers, electronic gaming systems and other portable devices that require protection against overvoltage. It can also be used for signal integrity and signal quality applications in systems that require unidirectional voltage protection. It is also broadly applicable in industrial, automotive, and computing applications.
4. Working Principle: The working principle of the MXLPLAD18KP75AE3 diode is based on the voltage-clamping principle, which involves reducing or ‘clamping’ the applied voltage to a predetermined level whenever a transient overvoltage surge exceeds the specified voltage. The diode is designed to clamp the voltage at a level called the ‘clamping voltage’, which is set lower than the specified voltage. The diode will automatically clamp the excess surge current when the applied voltage exceeds the clamping voltage. This allows the device to limit the damaging effect of an overvoltage surge and minimize the risks of permanent damage.
5. Advantages: The main advantages of the MXLPLAD18KP75AE3 are its bidirectional protection capabilities, fast response time, low clamping voltage, and low forward voltage drop. This makes it particularly suitable for low-current applications such as data signal line protection. In addition, the device has a wide temperature range and is RoHS compliant. The device is relatively small and has a low-profile design, making it suitable for use in small, space-constrained applications.
6. Conclusion: The MXLPLAD18KP75AE3 is a surface-mount unidirectional bidirectional transient voltage protection diode. It has wide applications in GSM mobile phones, PDAs, personal computers, electronic gaming systems and other portable devices that require protection against overvoltage. It is designed to withstand voltage up to 18KP75A in either direction, with a low forward voltage drop and wide temperature range. It provides excellent protection against overvoltage on data signal lines and is RoHS compliant. The device is ideal for low-current applications and can be used in space-constrained areas.
