TVS - Diodes

PTVS16VP1UTP,115 application field and working principle

TVS stands for Transient Voltage Suppressors, and also known as “transient voltage surge suppressors” (TVSS). It is a solid-state semiconductor device that instantly restricts surges from reaching sensitive electronics. These components are used to clamp transients to a safe level as currents and voltages fluctuate. PTVS16VP1UTP,115 is an unidirectional TVS diode, mainly used for over-voltage protection in different applications.

Application of PTVS16VP1UTP,115

The PTVS16VP1UTP,115 diode is used to suppress electrostatic discharge and voltage transients in a variety of applications such as consumer electronics, telecommunications equipment, industrial electronics, automotive electronics and other circuits.

Working Principle of PTVS16VP1UTP,115

When there is a sudden voltage spike, the PTVS16VP1UTP,115 TVS diode will conduct current to ground. This devices limits the voltages to a safe level by releasing the potential energy stored. As the temporary surge voltage continues to rise, this diode absorbs it and the same happens when the current increases drastically. After the surge is gone, the diode quickly returns to its non-conducting state and stops the flow of current.

Typical TVS diode schematic looks like the following:

In this schematic, the TVS diode is connected in reverse bias between drain and source, forming a triggered bidirectional protection element. The drain is usually grounded in order to ensure higher protection levels. A part of the RF signal is connected through capacitor C1 to the TVS diode gate, allowing RF signals to pass through the TVS diode.

Conclusion

PTVS16VP1UTP,115 is an unidirectional TVS diode and is used to protect sensitive equipment from voltage transients and electrostatic discharge. It works by absorbing the energy stored in a transient voltage spike and limiting it to a safe level, thereby protecting circuits from voltage-induced damages.
