TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are an essential component in protecting circuits from overvoltage or over current. They act as a barrier between the circuit and the external power supply, allowing for a safe and reliable operation of the device. The SRV05-4ATCT, in particular, is an advanced, high voltage, four line, TVS diode designed for use in automotive applications.This diode is mainly designed for the purpose of protecting the electronics from electrical spikes and has protective capabilities against transient voltage up to 4.5kV. It has a high surge power rating of 750W (8/20µs) and a low on-state voltage drop of 0.20 V@1A. It is available in a surface mounted package that can be easily soldered onto the PCB.The SRV05-4ATCT diode consists of three different parts; a zener diode, an MOSFET, and a P-channel MOSFET. When a positive overvoltage is applied to the diode, the P-channel MOSFET is activated and a current begins to flow through the diode. This current causes the voltage across the zener diode to increase until the zener voltage is equal to the applied voltage. When the zener voltage exceeds the threshold voltage, the MOSFET is activated and current flows through the P-channel MOSFET. This current in turn triggers the P-channel to turn off, thus limiting the current through the diode.The most common application of the SRV05-4ATCT diode is in automotive applications. Its high surge power rating and low on-state voltage drop makes it ideal for use in the protection of the ECU (engine control unit), fuel injectors, spark plugs, ignition coils, and other electronic components which are highly susceptible to electrical noise and overvoltage. It is also used for other non-automotive applications such as consumer electronics, power supplies, and industrial controllers.Overall, the SRV05-4ATCT is a versatile device designed for the protection against transient voltage and overvoltage. It is available in a small surface-mount package for easy installation and has proven to be very reliable in providing protection from electrical noise and other overvoltage events. The SRV05-4ATCT is an effective way to protect any device and its integrated components from any harmful spikes that may occur while in operation.
