TVS (Transient Voltage Suppressor) diodes are used in electrical equipment to protect them from the effects of high magnitude electrical surges. This type of diode is used in many applications and has become an integral part of the protection system in consumer electronics, automotive, industrial, telecommunication, computer, and medical manufacturers. The SMF48A-HE3-18 is a TVS diode designed specifically to provide the protection required by such sensitive equipment.

The SMF48A-HE3-18 is designed to operate within the 8.0-28.0V DC input voltage range. This range is wide enough to accommodate most industry specific applications. Its transient breakdown voltage is such that the device can protect equipment in the range of 725 W peak power dissipation. The device has low capacitance and the integrated circuits on either side of the diode are isolated from one another, preventing potential ground loops.

The working principle of the SMF48A-HE3-18 is based on the principle of Zener breakdown. This phenomenon, which is also known as avalanche breakdown occurs when the voltage applied to the junction exceeds the level of the Zener voltage breakdown at that junction. This causes the electron-hole pairs to be created in the depletion region on either side of the junction, allowing current to flow freely. The SMF48A-HE3-18 is able to achieve a Zener breakdown voltage of 28.0V, protecting sensitive equipment within the operating range.

The TVS diode is designed to protect against electrostatic discharge (ESD) and electro-magnetic interference (EMI). The device is able to absorb high magnitude electrical surges and dissipate them without any negative effect on the equipment. This makes it an ideal solution for protecting sensitive electrical equipment from high voltage disturbances.

The SMF48A-HE3-18 features a low total capacitance of only 33 pF, which helps reduce the amount of EMI. Additionally, the device is rated for 200V maximum peak repetitive surge voltage and can support up to 2500W peak power dissipation. It is designed to operate up to 28.0V DC and its nominal breakdown voltage is 24.5V when stressed over a max 10/1000us waveform.

The robust and reliable design of the SMF48A-HE3-18 makes it an ideal protection solution for a variety of applications. It can be used in a wide range of industry specific applications including automotive, telecommunication, medical, and consumer electronics. Additionally, its low total capacitance also makes it suitable for opoeration in high frequency applications such as wireless networks.

In conclusion, the SMF48A-HE3-18 is a TVS diode designed specifically to protect sensitive equipment from high magnitude electrical surges. It is designed to operate within 8.0-28.0V DC input voltage range and features a low total capacitance of 33 pF. It is rated for 200V maximum peak repetitive surge voltage and maximum 2500W peak power dissipation. Thanks to its robust and reliable design, the SMF48A-HE3-18 can be used in a wide range of industry specific applications including automotive, telecommunication, medical, and consumer electronics.
