Transient voltage suppressor (TVS) diodes provide robust, fast-acting ESD protection from damaging voltages that can exceed 5 kilovolts (KV) in an exercise of less than 1 nanosecond. SMDJ16C is a type of TVS-diode that is designed to protect A/V equipment, communication ports, digital and analog equipment and power supplies from static discharge and voltage spikes.

SMDJ16C is known as a "Unidirectional TVS-Diode", because it protects against voltage spikes in one direction only. It is rated for a working voltage of 16V and can withstand voltages up to 600W peak pulse current at a pulse time of 8.3μs. As long as the peak current does not exceed the maximum working voltage of the diode, the diode will remain operational. It is also important to note that the working temperature range should not exceed 125°C.

SMDJ16C offers superior protection from ESD, power transients and part-to-part transients. It is devices are designed to clamp the surge voltage and divert the surge current. When dealing with high voltages, the SMDJ16C TVS diode is highly effective in dissipating large amounts of surge current, facilitating protection against damage.

SMDJ16C TVS-diodes have several useful application fields. They are used in time-critical applications that require high-speed, efficient ESD protection. They are used extensively in consumer electronics, automotive, and industrial applications. In consumer electronics, they are used to protect cell phones, PDAs, digital cameras, MP3 players, computers and laptop computers from ESD events. In the automotive industry, they are used to protect sensors, controllers and other automotive electronics from damage. SMDJ16C TVS-diodes can also be used in industrial applications as they can protect against high-voltage transient events.

The working principle of the SMDJ16C is based on the “clamping effect” of the TVS-diode. In order to understand how this works, let’s take a look at the structure of the diode. The SMDJ16C has two terminals – an anode and a cathode. When the voltage applied across the two terminals exceeds the breakdown voltage, the diode will enter its “avalanche breakdown” and release a large amount of charge, thereby providing protection. The maximum current that can be “clamped” by the diode depends on its structure and the breakdown voltage.

In addition to the clamping effect, the SMDJ16C also utilises the “snubber effect”. This effect occurs when the voltage across the two terminals is reduced rapidly. This rapid reduction or “snubbing” of the voltage reduces the energy present in the system and therefore reduces the possibility of damage.

Overall, the SMDJ16C is a very reliable and efficient type of TVS-diode and provides a superior level of protection against ESD, power transients and part-to-part transients. It can be used in a variety of application fields including consumer electronics, automotive and industrial applications, and its unique clamping and snubber effects provide superior protection compared to other types of TVS-diodes.
