TVS - Diodes

TVS, or transient voltage suppressors, are electronic components used to protect a device from high-voltage transients or surges, by suppressing any voltages over a predetermined threshold. The NSPM0051MUT5G is a TVS diode, designed to provide EMI/RFI noise suppression for a range of applications.

Application Field

The NSPM0051MUT5G is capable of providing protection from high-voltage transients and surges on devices exposed to outdoor power distribution lines, automotive electrical systems, electrical motors, non-medical consumer and industrial equipment, and many other applications. It can also provide protection for Ethernet lines, USB ports, and other communication links exposed to harsh environments. It is a highly reliable solution for circuit protection and offers a wide operating temperature range from -55°C to +125°C.

Working Principle

The working principle of a TVS diode is relatively simple. When a surge in voltage or transient occurs, the diode acts like a load, diverting the flow of electricity and dissipating the energy as heat. The diode inherently absorbs or redirects energy from surges and transients, thus protecting the circuit it is connected to. The NSPM0051MUT5G contains a multi-layer of protection with radio frequency interference (RFI) filters and metal oxide varistors (MOV) technologies, making it an optimal choice for wide range of circuit protection applications.

Benefits and Features

The NSPM0051MUT5G has an ultra-small size of 1208, which helps to save board space and simplify the design. It also features a wide operating frequency range of 0-10GHz and EMI susceptibility of 15dB to protect multiple signals simultaneously from interference. Thanks to its high peak pulse power rating of 41.6A (8/20μs), the diode minimizes the downtime caused by device failures due to overvoltage, and offers superior protection for the attached device. Additionally, the NSPM0051MUT5G is RoHS compliant and supports lead-free assembly, making it an ideal solution for environmental safety.

Conclusion

TVS diodes are highly durable components used in a wide range of application for EMI/RFI filters and protection against voltage surges and transients. The NSPM0051MUT5G is specifically designed to protect a vast array of electronic circuits and communication lines, in spite of harsh environments. Additionally, it offers reliable performance, high peak pulse power rating, and a wide operating temperature range.
