Varistors, also known as voltage-dependent resistors (VDRs), are a type of semiconductor device equipped with two terminals. The electrical resistance of varistors drastically decreases with the increase in voltage, allowing them to be used in circuit protection applications. Together with MOVs (metal oxide varistors) and TVSs (transient voltage suppressors), varistors are part of the surge protection family. In this article, we will focus on TVSs and 82550110, one of its main applications and its working principle.

TVSs are used to protect sensitive electronic components against electrical spikes. A typical application for TVSs is surge protection in automotive electronics. 82550110 is a TVS diode specifically designed for this purpose. It has a breakdown voltage of 20V, which gives it a wide operating range. The 82550110 is typically used for ESD (electrostatic discharge) protection, surge protection, and lightning/transient protection in automotive and industrial applications.

The 82550110 is a two-lead TVS diode that contains an N-channel metal oxide semiconductor (MOS) device. The diode is built using a silicon-doped polycrystalline silicon substrate, which is called the MOSFET. The MOSFET has a gate terminal, which allows current to flow from the anode to the cathode when a certain voltage is applied. Additionally, the MOSFET has a clamping voltage, which prevents any further current flow once it is reached.

The 82550110 works by suppressing voltages that exceed the protected voltage range. When the voltage surpasses the breakdown voltage, the protection kicks in. The MOSFET rapidly conducts the current, and the diode becomes conductive, allowing the current to flow into the protected circuit. This protects the circuit from damage due to the voltage spike.

The 82550110 is an ideal product for automotive and industrial surge protection applications. It is designed to protect delicate circuits from any electrical risks associated with voltage peaks. The TVS diode is proven to be an effective and reliable surge protection product, and is widely used in automotive applications where high voltage spikes occur frequently.
