Transient Voltage Suppression (TVS) diodes are used to protect sensitive components from electrical surges, latch-up, and ESD. They are an important component in power substations, telecommunications networks, industrial equipment, and consumer electronics. The 3.0SMCJ43CATR is a unidirectional, surface mount TVS diode designed for high-current transient protection applications with a reverse breakdown voltage of 43V.

The working principle of the TVS diode is based on two semiconductor junctions. The anode and cathode electrodes are connected to the two different regions of a semiconductor, which can be either an N-type or a P-type. When a voltage spike occurs between the anode and the cathode, the diode switches from its high impedance state to a low-impedance state due to the break down of both junctions. This allows current to flow through the diode, clamps the voltage spike, and prevents the voltage from rising further.

The 3.0SMCJ43CATR is designed for high-current transient protection applications and features a peak power rating of 9.6kW for an 8/20μs waveform with 10% VDD clamping. It has a leakage current at 43V of 15μA maximum. It has a breakdown voltage of 43V and a reverse stand-off voltage of 30.5V. It also has a VBR of 43V at 25˚C. The diode has a peak pulse current rating of 10A and a peak pulse power dissipation of 700W. It has a breakdown voltage of 43V and a capacitance of 2.7pF.

The 3.0SMCJ43CATR is suitable for use in a variety of industrial, military, railroad, telecom, and consumer applications. It is suitable for use in applications that require protection from over voltage, electrostatic discharge, and lightning surge protection. The diode is used to protect electronic equipment and components from high voltage transient surge. It can also be used to protect low impedance signal line circuits such as USB, FireWire, and Ethernet from voltage spikes.

The 3.0SMCJ43CATR is a bi-directional TVS diode that is used to protect sensitive components and circuits from over-voltage and electrostatic discharge. The bi-directional feature of the diode means that it can provide protection in both the forward and reverse voltage direction, which is beneficial for applications such as sensitive circuits connected to the AC mains. The diode has a reverse breakdown voltage of 43V and a peak power rating of 9.6kW. It is suitable for use in a variety of industrial, military, Railway, telecom, and consumer applications. It can be used to protect electronic equipment and components from high voltage transient surges, ESD, and latch-up.
