TVS - Diodes, also known as Transient Voltage Suppressors, are specialized devices that are designed to protect electronic circuits from voltage spikes, transients and electrical surges. The SMBJ48CA-TR is a popular protection device. This article will explain its application field and working principle.

The SMBJ48CA-TR is a bi-directional device, meaning that it can protect circuits from voltage transients originating from both directions. It is specifically designed to protect sensitive components from damage caused by electrostatic discharge (ESD). At high temperatures, the device can protect up to 48 volts and its reverse stand-off voltage is 40 volts for 50W of power. This device has a clamping voltage of 67 volts for 10A power.

The SMBJ48CA-TR is most commonly used in industrial and automotive applications. It is commonly used to protect voltage sensitive systems from voltage spikes and overvoltage transients in harsh environments. It can also be found in wireless systems, baseband units, radio-frequency transceivers, and low power automotive power systems.

The SMBJ48CA-TR works in a unique way. When a voltage transient or surge is detected, the device automatically conducts the surge current away from the protected circuit. This is done by switching into a low impedance state, to eliminate the damaging voltage and protect the sensitive components.

In addition, the device is able to regulate a steady supply of voltage and efficiently dissipate excess transient energy. This ensures that the circuit is protected from both the voltage spike and the consequent thermal and mechanical stresses that are caused by the spike. The device also features a low capacitance gate that is able to accurately sense the voltage transients.

The SMBJ48CA-TR has been designed to be highly reliable, and it is able to withstand temperatures ranging from -55C to 125C. The device has a high peak pulse power of 1500W, and is RoHS compliant. It is available in both surface mount and through-hole packages.

The SMBJ48CA-TR is a useful and highly reliable device for protecting sensitive components from voltage transients. It is designed to quickly and efficiently divert surge currents away from the voltage sensitive systems, save them from further damage due to transient current. It is widely used in automotive and industrial systems, and its high temperature resistivity and low capacitance gate make it ideal for a range of applications.
