The SMBJ15CATR is a 15 watt, unidirectional, bi-directional, unidirectional, and bi-directional transient voltage suppression (TVS) diode. It is a member of ON Semiconductor’s series of TVS Diode Arrays, which are designed to protect sensitive electronic systems from voltage transients caused by electrostatic discharge (ESD), electrical fast transients (EFT), lightning, and other inductive transients. TVS diodes can provide both clamping and shunting of high-energy transients, and the SMBJ15CATR exceeds the industry’s highest Surge Integrity levels to ensure continued protection for sensitive equipment.

The SMBJ15CATR is manufactured and tested in accordance with the International Council on Large Electric Systems (CIGRE) standard for surge withstand capability. This ensures that the TVS diode meets the highest levels of surge protection for sensitive equipment. The device is rated at 15 watts, with a breakover voltage of 28 volts, and a leakage current of 2 microamperes. It has a low operating temperature of -55 to +150°C, making it ideal for applications in extreme environments.

The SMBJ15CATR provides superior ESD protection. It is the ideal choice for protecting sensitive components and systems against fast transients of high-energy bursts. The device is designed to be connected between power and signal lines in order to provide protection against transient voltage spikes. The SMBJ15CATR ensures a tight clamping voltage to allow efficient suppression of high-energy transients. Its high surge capability and low leakage current ensures consistent protection of sensitive and vulnerable components.

In order to understand the working principle of the SMBJ15CATR TVS diode, it is necessary to understand the anatomy of the device. The device consists of two terminals: an anode and an cathode. The anode is connected to the positive power supply line, while the cathode is connected to ground or the negative power supply line. The SMBJ15CATR works by conducting current through the diode when the voltage across it exceeds the breakover voltage. The diode will then conduct the current until the voltage falls back below the breakover voltage. This process of clamping and shunting is what provides effective protection against high-energy transient voltages.

The SMBJ15CATR is designed for applications such as TV sets, air conditioners, refrigerators, computers, and power equipment. This TVS diode can be used in a wide variety of applications, including ESD protection of IC\'s, components, devices, and systems. The device has a broad operating temperature range of -55 to +150°C, making it suitable for many environments. The device is also RoHS compliant, making it ideal for applications where hazardous materials are of concern.

The SMBJ15CATR is an effective and reliable solution for protecting electrical systems and components against transient voltage spikes. Its high surge capability and low leakage current ensures consistent protection of sensitive and vulnerable components. The device is suitable for a wide variety of applications, and has a broad operating temperature range, making it ideal for use in extreme environments.
