TVS - Diodes, also known as Transient Voltage Suppression Diodes, are devices that provide protection to electronics from voltage spikes found in the power. These devices provide protection from both electrical over- staging (EOS) and electrostatic discharge (ESD). The PKP85CE3/TR13 is a popular TVS Diode used to provide surge protection from ESD.

The PKP85CE3/TR13 is rated for 3.75-5.25V, with a stand-off voltage of 6.1V. The device has five pins, with the body ground as the first pin. It also has a rated power dissipation of 500mW and operating temperature range from -65 to +125 degrees Celsius.

The application of the PKP85CE3/TR13 primarily lies in consumer electronics. It can be found in consumer electronic products such as computers, tablets, and phones, as well as industrial equipment. The device is small in size and relatively inexpensive. Its small size makes it easy to find a place in compact circuit board designs, making it a popular choice for ESD surge protection.

The operating principle of the PKP85CE3/TR13 is based on the principle of Zener clamping. The device works by automatically limiting the surge voltage by clamping it down to the clamp voltage, which is typically below the breakdown voltage of the board components. The device works by absorbing the ESD spike energy, resulting in a small voltage rise. The current flow through the diode is very small compared to the spike energy, ensuring that the device does not dissipate the energy too quickly.

This small current allows the device to provide an effective clamping voltage that ensures that electrical overstressing (EOS) or ESD events will be limited to an acceptable level. The device works in both DC and AC conditions. For better protection, the device can be used in combination with other protective components such as MOVs and Transorb diodes.

In conclusion, the PKP85CE3/TR13 is a popular TVS diode for providing ESD surge protection in consumer electronics. The device works by using the principle of Zener clamping. It can be used in both DC and AC conditions, but is most effective when used in combination with other protective components. This small, cost-effective device is an ideal choice for providing protection from EOS and ESD events.
