TVS diodes are electrical devices designed to protect sensitive electronic equipment from voltage transients. The MSMBJ170CA/TR (Transil) is a bi-directional TVS diode designed for transient overvoltage protection. It was designed to provide high levels of transient overvoltage protection for applications such as personal computers, PC peripherals, telecom equipment, office or home automation equipment, or any other consumer or industrial devices with a low voltage power supply.
The MSMBJ170CA/TR is a surface-mount, low-capacitance device offering electrostatic discharge protection up to 15 kV (8/20µs) and IEC level 4 compliance. It provides ESD protection from -15 kV (contact) and -8 kV (air) without any negative effects on the protected equipment. It also offers low clamping at just 6.5V and fast response less than 1 nanosecond, with the added flexiblity of being available in both axial and dual-in-line packages.
The MSMBJ170CA/TR is designed to provide comprehensive protection for sensitive components and reduce failures due to electrostatic discharges or transients, while maintaining electrical and thermal performance. It is ideal for protecting equipment in a variety of environments, from extreme voltage surges to periodic transients or short duration surges. With its small size and light weight, it is also easy to install and maintain, thus providing the best protection for sensitive electronic equipment.
The basic principle of the MSMBJ170CA/TR is based on the voltage clamping effect. When an excess overvoltage is applied on the TVS diode\'s anode, the diode will begin to conduct, limiting the voltage across the terminal pins. This process is called “clamping” and it serves to protect the connected equipment from harmful overvoltages. The TVS diode works thanks to the avalanche effect, where electrons are accelerated when a certain voltage is applied across the diode. This leads to the diode being able to absorb larger amounts of current than a standard diode could support, and thus protects the connected equipment from damage.
The MSMBJ170CA/TR can provide electrical protection in applications where the supply voltage is 5.0V and the output or connected equipment has a low impedance. It also has a very low capacitance, allowing it to be used in high speed digital circuits with no negative effects on performance. The MSMBJ170CA/TR provides high surge current handling capability, allowing it to handle spikes ranging up to 1.4 A, thus providing reliable overvoltage protection for a variety of electronic equipment and systems.
In summary, the MSMBJ170CA/TR is a versatile, low-capacitance, bi-directional TVS diode designed to provide electrostatic discharge protection up to 15 kV (8/20µs) and IEC level 4 compliance. Its low capacitance and fast response makes it ideal for high speed digital applications that require reliable overvoltage protection. Its small size and light weight makes it easy to install and maintain, thus providing comprehensive protection for sensitive electronic equipment and systems.
