3.0SMCJ110CATR

TVS (Transient voltage suppressors) diodes are designed to protect sensitive electronics components from damage by suppressing voltage transients from passing through. The 3.0SMCJ110CATR is a unidirectional TVS diode that can be used in various applications.

Application Field

This diode can be used in a variety of applications, including in areas where high voltage transients can occur, such as automobile ignitions, electrostatic discharge, and LCD panels. It is also often used in power supplies and high-power data communication systems.

This device is suitable for protecting a wide range of devices from transient over-voltage. It offers a reverse breakdown voltage of 110 volts, as well as an operating temperature range of -55 to 125°C. This makes it an ideal choice for use in extreme environmental conditions, such as automotive and industrial applications.

Working Principle

When a transient event occurs, the diode will act as a clamp, working to redirect the flow of current to protect sensitive components from damage. It does this using a special construction, which is made up of a high-voltage Zener diode and a MOSFET transistor.

The Zener diode is designed to break down at a predetermined voltage, allowing current to flow through it in a controlled fashion. The MOSFET then acts as a switch, automatically engaging when voltage surpasses the Zener diode’s breakdown voltage. This allows current to be absorbed and dissipated, and for the voltage to be clamped at a safe level.

The 3.0SMCJ110CATR is designed to work in a similar way, helping to protect delicate electronic components from damage caused by voltage transients. Its reverse breakdown voltage of 110 volts and wide operating temperature range make it an ideal choice for use in automotive and industrial applications.
