Transient Voltage Suppressors (TVS) are the most popular device used in power protection circuits across the industry. TVS devices provide protection against momentary voltage surges generated by lightning and EMD events. Most applications require both a TVS and fuses to provide a fully redundant power protection system. The SMF36A-E3-18 is a popular transient voltage suppressor diode in the TVS diode family. It is a 3.3V unidirectional transient suppressor constructed in compliance with RoHS standards.

The SMF36A-E3-18 transient voltage suppressor diode is a low voltage, bidirectional, low capacitance diode specifically designed for mobile device applications such as smartphones, tablets, wireless audio devices, and USB chargers. It features a 3.3V operating voltage and an 18V breakdown voltage that offers reliable protection against high voltage transients. In addition, the SMF36A-E3-18 has a low clamping voltage of just 0.1V, making it suitable for power-sensitive electronics.

The SMF36A-E3-18 is usually incorporated in the application circuit when the system must meet international surge/transient requirements. This ensures the application will react quickly, absorb high peak currents, and protect the device from ESD & EFT events. It is a multi-device solution incorporating ESD, Surge, and EMI protection for the entire circuit. The TVS diode performs the task of clamping the input voltage peak to the breakdown voltage of 18V, allowing the device to stay protected during operating conditions and to prevent permanent damage in the event of a transient voltage surge.

Apart from its reliable protection against ESD & EFT events, the SMF36A-E3-18 features a low capacitance of just 0.1pF, making it suitable for power-sensitive circuits. This low capacitance helps to reduce the application circuit\'s power consumption, making it more energy efficient. In addition, the diode\'s low forward voltage of 0.18V ensures that it does not affect the signal integrity of the circuit, allowing for uninterrupted high-speed data transmission.

The SMF36A-E3-18 is an ideal choice for a variety of applications, including consumer electronics, automotive, wireless and lightning protection, DSL, and POE. It features a fast response time of less than 5ns and can easily handle transient voltages of up to 600W peak power. The SMF36A-E3-18 is RoHS compliant, making it a safe and environmentally friendly solution for power protection in your application.

In addition to its reliable protection, the SMF36A-E3-18 offers many other benefits, including easy handling, low cost, and small size. The TVS diode can be easily incorporated into an application circuit and is designed to provide protection for up to 10 years. It comes in a small 3-pin miniature SMA package, which allows for easy integration into an existing system. The SMF36A-E3-18 is also available in a variety of voltage ratings, making it suitable for a wide range of applications.

In conclusion, the SMF36A-E3-18 is a robust and reliable transient voltage suppressor diode from the TVS diode family. Its 3.3V operating voltage and 18V breakdown voltage make it an ideal solution for consumer electronics, automotive, wireless, lighting protection, DSL and POE applications.
