TVS - Varistors, MOVs are devices that protect electrical systems from excessive voltage transients. They are designed to clamp the voltage at a certain level to keep the systems safe. The V150LC20APX2855 is a device that falls in this category.

The device is a bi-directional thyristor surge protector that is mainly used in automotive and consumer electronics. Its junction capacitance is designed to keep the surge current flowing within specified limits. It has an 18 V operating voltage and a peak current rating of 2855 A (8 × 20 μs). Its peak surge current rating is 1650 A (8 × 20 μs).

The V150LC20APX2855 is primarily used to protect automotive electronics from high voltage surges caused by inductive loads, such as alternators or starter motors. It helps in preventing damage to the PCBs and components that are placed close to the power source. The V150LC20APX2855 can also be used as a general purpose line protection device for low voltage DC power supplies.

The device is constructed of an N-type silicon material, which is designed to provide fast switching speeds. It operates in the avalanche region of the PN junction, ensuring that the clamping voltage is maintained at the specified level. The device is designed to shut off the surge current within a specified interval, thus protecting the power system from any further harm.

The working of the V150LC20APX2855 is simple. When a high voltage transient or surge appears across the device, the N-type material starts to conduct, clamping the voltage at a specified level. The device is designed to sense this surge, and in turn, shut off the flow of current through the power system. This helps in preventing damage to the sensitive components within the system.

The V150LC20APX2855 is a device that can be used in a wide range of applications, including consumer electronics, automotive electronics, and general purpose line protection. Its N-type material provides fast switching speed, ensuring that the voltage is clamped at the specified level. The device is also designed to shut off the flow of current through the power system when a surge appears. This helps in preventing damage to the sensitive components within the system.
