TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are electrical components designed to protect circuits and connected devices from voltage spikes, such as those caused by electrostatic discharge (ESD). They come in many varieties with varying working principles and application fields. MAPLAD18KP33AE3 is a TVS diode designed for the protection of I/O connections in electronic applications.

MAPLAD18KP33AE3 Application Field

MAPLAD18KP33AE3 is mainly used for data ports and serial ports, such as USB, Ethernet, VGA, HDMI, and other related I/O connections. It was designed for both consumer and industrial products. It is ideal for use in consumer products such as cell phones, tablets, laptops, and PDAs, where it provides protection from static electricity, lightning, and impulse transients. In industrial applications, it can be found in automation, factory equipment, instrumentation, telecommunications, and medical systems.

MAPLAD18KP33AE3 Working Principle

MAPLAD18KP33AE3 works by clamping incoming voltage spikes, both positive and negative, to safe levels. The voltage spike is absorbed and dissipated as heat, thus preventing damage to the components. This diode has a low breakdown voltage of 1.75V, which helps to protect circuitry from over-voltage conditions. The storage capacitance of 340pF helps to reduce power supply noise, and the ESD performance of at least 30kV helps to ensure protection from static electricity.

MAPLAD18KP33AE3 is designed with a rugged lead frame that is able to withstand high pressure and high temperatures. This helps prevent crack formation on the lead frame due to thermal and mechanical stresses. The device is also RoHS compliant, meaning it does not contain any hazardous materials.

Conclusion

MAPLAD18KP33AE3 is a reliable and robust TVS diode that is designed for a wide range of I/O port protection applications. Its low breakdown voltage and high ESD protection help to ensure reliable operation, and its rugged lead frame allows it to withstand high pressure and temperatures. It is RoHS compliant and can be used in both consumer and industrial applications.
