TVS - Diodes

Transient Voltage Suppression (TVS) diodes are designed to protect sensitive electronics from excessively high voltage pulses. They are widely used in telecommunications devices, consumer electronics, motor control systems, sensors, and other applications requiring surge and overshoot protection. The 5KP170CAE3/TR13 is an example of a TVS diode, and this article is intended to provide a brief overview of the application field and working principles associated with this type of diode.

Application Field

TVS diodes are widely used in a variety of applications due to their ability to protect sensitive electrical components from electrical transients or "spikes". Although the 5KP170CAE3/TR13 is designed to protect against overvoltage from 8V to 170V and surge up to 8A of current, TVS diodes can be found in applications where lower voltages (up to 40V) and pre-compliance testing are needed. Common applications include surge protection for AC power supplies, USB ports, car batteries, and other automotive electronics in addition to industrial control systems and aerospace/defense.

Working Principles

The TVS diode is a form of semiconductor diode that is specially designed to protect against overvoltage or surge conditions. The diode works by conducting current when the voltage it is exposed to exceeds a certain threshold (clamping voltage). This current is then later dissipated through a reverse-biased diode, effectively protecting the sensitive components by limiting the maximum voltage to a safe level. These diodes are available in several configurations including axial, SMD, and bi-directional.

The 5KP170CAE3/TR13 is a series of Ultra Fast, bi-directional TVS diodes for use in automotive electronics. This diode can be used to protect against overvoltage ranging from 8V to 170V and can dissipate up to 8A of current. The diodes have a low clamping voltage and are designed to respond quickly to transients. This series of diodes are qualified to AEC-Q101 automotive standards and are designed to be used in a variety of automotive applications.

Conclusion

TVS diodes are an important component in the protection of sensitive electronics from transients and overvoltage. The 5KP170CAE3/TR13 is an example of these diodes, designed to protect against voltages of 8V to 170V and can dissipate up to 8A of current. These diodes are qualified to AEC-Q101 automotive standards and are widely used in a variety of automotive and other applications requiring surge and overshoot protection.
