TVS diode (Transient Voltage Suppressor Diode) is a unidirectional device used to protect sensitive components from voltage spikes and transients which would otherwise cause permanent damages or cause unreliable operation of electronic systems. SM5S15ATHE3/I is one of such diodes used to provide protection against lightning, electrostatic discharge (ESD) and inductive switching, etc. in industrial, automotive and communication applications.

Working Principle of SM5S15ATHE3/I:

SM5S15ATHE3/I is a voltage dependent TVS device, which is designed to protect sensitive electronic components from voltage transients and spikes. As the voltage exceeds the threshold voltage of the device, it is immediately triggered to conduct, allowing the excess charge to be dispelled quickly. When the spike is finished and the voltage drops below the reverse breakdown voltage, the device immediately stops conducting and returns to its non-conducting state.

SM5S15ATHE3/I Application field:

SM5S15ATHE3/I can be used in various situations where protection against voltage transients is required, such as:

• Automotive systems – Used to protect sensitive electronic components from high voltage and false signals caused by the voltage spikes that may occur in automotive applications.
• Lightning strikes – Used to protect electronic equipment from electrical surges caused by lightning strikes.
• Electrostatic discharge – Used to provide protection against ESD, which can cause irreversible damage to sensitive electronic components.
• Inductive switching – Used to provide protection against voltage surges that may occur when inductive loads are connected or disconnected.
• Industrial applications – Used to protect sensitive electronic components from voltage transients in industrial applications.
• Communication applications – Used to protect sensitive electronic components from the high voltage caused by electromechanical noise in communication systems.

SM5S15ATHE3/I is a surge protection device designed to protect sensitive electronic components from transient and voltage spikes. Its wide application field and working principle make it an ideal device for protecting electronic equipment from voltage transients.
