Introduction to TVS – Diodes

A Transient Voltage Suppression (TVS) diode is a solid state device designed to protect sensitive equipment from transient electrical over-voltages or surges. It is usually used as a one-way switch between two terminals, and acts like an electrical fuse to limit dangerous surges and protect invaluable equipment from damage or destruction. TVS diodes can be used in any circuit or equipment where there is a need to protect against power transients, such as automotive, consumer electronics, computers, telecommunications, and many other applications.

DVIULC6-2M6 TVS – Diodes

The DVIULC6-2M6 is a dual unidirectional TVS diode with excellent clamping capability designed to protect sensitive electronics from large voltage transients in the 6-2V range. It has an operating voltage of 6 V and a clamping voltage of 18V. This device has a small size which allows for a low profile design and is RoHS compliant (Restriction of Hazardous Substances Directive). The DVIULC6-2M6 is designed to provide a faster response time and higher surge current handling capabilities than competitors. It can withstand large surge currents up to 25A (8/20 microseconds waveform) and transient voltages up to 800V (unidirectional surge). This device also has a wide operating temperature range of -40°C to 125°C.

DVIULC6-2M6 Application Fields and Working Principle

The DVIULC6-2M6 is widely used in automotive, computing, consumer electronics, telecommunications, and many other applications that require power supply protection from transients. It is highly effective against power transients caused by static electricity discharges, lightning, or other events. The working principle of the TVS diode is based on the avalanche breakdown effect. When the transient voltage exceeds the reverse breakdown voltage of the diode, a large amount of current is injected into the diode and dissipated as heat at a rate of 175W/sec. The heat energy generated by the diode is dissipated quickly, protecting the circuit from damage.The DVIULC6-2M6 is designed with a wide operating voltage range that is capable of clamping voltages up to 18V, making it suitable for a variety of applications. The device also has a fast turn off time at 16 nanoseconds and a maximum voltage rate of change (dV/dt) of 7500V/µs for unidirectional protection.

Conclusion

In conclusion, the DVIULC6-2M6 is a versatile and reliable TVS diode capable of providing excellent power transient protection in a wide variety of applications. The device has a fast response time, wide operating voltage range, and high surge current handling capabilities, making it one of the most reliable TVS devices on the market.
