TVS - Diodes

A TVS diode is a type of diode specifically designed for transient voltage surge suppression. TVS diodes are also known as surge suppression diodes, or SIP diodes. They are typically used to protect electronic circuits from damage due to overvoltage conditions, and can be found in a wide variety of consumer electronic products such as personal computers, servers, and even smartphones.

SMB10J18-E3/52 Application Field and Working Principle

SMB10J18-E3/52 is a surface-mount unidirectional transient voltage suppressor (TVS) diode designed for transient overvoltage protection. It has an ultra-small package and a wide operating working voltage range of 4.5V to 18V. This TVS diode is suitable for use in a variety of applications such as automotive electronics, communication systems, computer and office equipment, tools, medical and consumer electronics equipment.

The SMB10J18-E3/52 is designed to provide a clamping voltage that is independent of the power dissipation. The working mode is to absorb overvoltages, or “transients”, in the reverse-biased direction. When an over-voltage occurs, the diode conducts a surge of current and then returns to a non-conduction state after the voltage returns to normal levels. This provides superior transient protection, compared to Zener diodes, which require regular maintenance and monitoring. The devices are also RoHS compliant.

The SMB10J18-E3/52 is also suitable for use in high-frequency devices such as personal computers, servers, and mobile phones, as well as in a wide variety of industrial applications. It has an ESD protection capability of 8kV HBM (human body model), an operating temperature range of -55C to +125C, and a peak pulse power dissipation of 1000W at 1us. This TVS diode has an ultra-small package outline (package size is 0.4mm x 0.4mm x 0.34mm). The device is designed for use on Printed Circuit Boards (PCB), and features a fast response time of under 0.5us.

Conclusion

The SMB10J18-E3/52 TVS diode is capable of providing superior transient protection against voltage surges, and is suitable for use in a wide variety of electrical and electronic applications as well as high-frequency devices. The device features a wide operating working voltage, an ESD protection capability of 8kV HBM, and an ultra-small package outline of 0.4mm x 0.4mm x 0.34mm. It also has a fast response time of under 0.5us, making it ideal for use in a variety of applications where fast response times are necessary.
