TVS Diodes

TVS diodes are transil diodes used to protect electronic equipment from overvoltage, lightning strikes, and other electromagnetic interference (EMI) transients. Typically, TVS diodes are used in pairs, each protecting against one type of transient, and in a variety of circuit architectures. Commonly used in automotive, general-purpose, and industrial applications, TVS diodes provide additional protection against voltage spikes, noise, and interference on signal lines.

SMB10J18HE3/5B Application Field and Working Principle

The TVS diode SMB10J18HE3/5B is an SOT- ox-style TVS diode designed for applications where a low clamping voltage and fast response time is required. This diode can be used to protect sensitive components and circuits used in computers, automotive electronics, and telecommunications equipment. Its working principle is based on a high-speed avalanche breakdown, which occurs inside the device and allows it to function quickly and effectively in order to clamp transients and provide protection from overvoltages.

The SMB10J18HE3/5B has a breakdown voltage of 19V, and is designed to be operated with a maximum working voltage of 18V. It is able to clamp transients up to 25A and has a fast response time of 8ns. It is also resistant to both high temperatures and ESD, and has an operating temperature range of -65°C to 150°C. In order to maintain its integrity over time, the diode includes an integrated ESD protection mechanism and an anode. This ensures that the diode is protected from overvoltages and keeps the protected circuits safe.

The SMB10J18HE3/5B is designed to be used with standard components, such as diodes, transistors, relays, and fuses. It has a small package size, the ability to be soldered in place, and it is easily integrated into applications. This makes it ideal for applications where protection against both overvoltage and ESD is required.

The SMB10J18HE3/5B is an excellent choice for applications requiring fast, reliable protection from transients. It is a cost-effective solution for designers looking to protect sensitive components and circuits from overvoltage transients. The diode’s fast response time and low clamping voltage make it ideal for applications such as cars, computers, and telecommunications equipment.
