This article is about the SMBJ75CAHR5G TVS - Diodes. TVS - diodes, also known as transil diodes, are components that protect against transient surge voltages, ensure signal integrity, and protect circuits such as those found in communication and automotive systems from the resulting damage caused by voltage transients. The SMBJ75CAHR5G is specifically designed with the purpose of providing high-reliability electrostatic discharge (ESD) protection to operate over a wide temperature range.

The SMBJ75CAHR5G TVS - Diodes has a wide range of application fields. It is widely used in USB and other peripheral device applications and ideal for secondary protection of integrated circuits (ICs). It is commonly used for protection against voltage transient such as electrostatic discharge (ESD), lightning, and inductive switching in consumer, automotive, and industrial applications. Additionally, the device is suitable for protecting high-speed data lines such as USB, PCI Express, HDMI, V-by-one, Ethernet, and multipoint data transmission systems and in power supply circuits against electrostatic discharge (ESD), surge, and overload.

The working principle of the SMBJ75CAHR5G is based on the avalanche breakdown effect. When the forward voltage applied to the device reaches a certain level, the avalanche breakdown effect occurs, resulting in a large current of hundreds of mA flowing into the anode and minimizing the potential difference between the anode and cathode. This allows the device to provide an increased degree of protection, clamping quickly and effectively from the moment a voltage transient occurs. Furthermore, the device is designed to have a temperature coefficient of -3.8 to -3.5%/°C, making it ideal for automotive applications requiring a wide temperature range performance.

The SMBJ75CAHR5G is specifically designed as a low capacitance bidirectional TVS diode that provides ESD protection for USB and other peripheral applications. It is designed with a working peak reverse voltage of 75 volts and a working peak pulse power of 800 watts. Its clamping voltage is between 10 V and 17 V, making it ideal for use in applications requiring a low clamp voltage. Furthermore, the device has a low leakage current of 3 μA and a fast response time of 1 nanosecond.

In conclusion, the SMBJ75CAHR5G TVS - Diodes is a low capacitance bidirectional TVS diode designed to provide an increased level of protection from transient surge voltages. It is widely used for protection against voltage transient such as electrostatic discharge (ESD), lightning, and inductive switching in consumer, automotive, and industrial applications. The device is designed with a working peak reverse voltage of 75 volts and a working peak pulse power of 800 watts. Furthermore, it has a low leakage current of 3 μA and a fast response time of 1 nanosecond. The device is also designed to have a temperature coefficient of -3.8 to -3.5%/°C, making it ideal for automotive applications requiring a wide temperature range performance.
