1.5SMC43AHR7G TVS - Diodes are most commonly used to protect critical components from voltage and current transients that can occur as a result of electrostatic discharge, surges, and inductive load switching. TVS - Diodes provide higher levels of protection than conventional diodes or thyristors, as well as fast response times for a wide range of transient events. These devices differ from conventional diodes and thyristors in that they incorporate multiple layers of silicon protection with avalanche breakdown characteristics, which provide additional protection against transient events.The 1.5SMC43AHR7G TVS - Diode comprises two stages of protection capable of operating in avalanche or breakdown mode. In the first stage, the device acts as a Zener diode, where the diode will undergo a breakdown phenomenon when the reverse voltage reaches a certain critical value. This can be thought of as an avalanche breakdown, where the current across the diode increases exponentially with increasing voltage. In this stage, the device will provide protection against overvoltage transients. The second stage of protection is accomplished through an integrated MOSFET switch, which provides protection against high-current transients.When a transient event occurs, such as an electrostatic discharge or surge, the two stages of protection within the 1.5SMC43AHR7G TVS - Diode allow for a lower clamping voltage, faster response times, and better protection than traditional diodes. When the transient event exceeds the breakdown voltage of the diode, it will begin to conduct, and the MOSFET switch will activate. The MOSFET switch will limit the current through the diode to a predetermined level, protecting the device from the high-voltage transient. The device is able to absorb the energy of the event and divert it to the load, dissipating the energy harmlessly.The 1.5SMC43AHR7G TVS - Diode is widely used in applications requiring protection from surges, electrostatic discharge, and inductively-loaded switching transients. It is commonly used in automotive, telecommunications, industrial, medical, and consumer applications where high levels of protection are needed from voltage transients. The device is also typically used to protect voltage sensitive components from high voltage transients.The 1.5SMC43AHR7G TVS - Diode provides superior protection by using two stages of protection. The diode will commence breakdown when the reverse voltage reaches a certain level and activate the MOSFET switch to limit the current to the device. This ensures that the device can absorb the energy of the electrical transient and divert it to the load, dissipating it safely and without damage to the connected components. The device is capable of providing protection against a wide range of voltage and current transients, making it ideal for use in automated production and test systems, as well as for consumer applications.
