The MXSMCJ28CA Transient Voltage Suppressor (TVS) Diode is used primarily for surge protection of sensitive electronic equipment from electrostatic discharge (ESD), electro-magnetic interference (EMI), and electrical fast transient (EFT) which also affect automotive electronics and any other electronics system existing in harsh environments. It is one of the most popular models of TVS diodes in the market.

The MXSMCJ28CA is an unidirectional protection device with a dual common mode to meet the requirements of video, data and I/O applications. It has an ultra-low dynamic capacitance, and an integrated solder and water-resistant protection, and is RoHS compliant. On top of all this, it also has installation flexibility with its SMD (Surface-mount device) and TO-220AB-3, with wide stand-off spacing for easier, more reliable mounting.

The MXSMCJ28CA has a breakdown voltage of 26.4V, a clamping voltage of 52V, and a peak pulse power rating of 850W. It has an ESD protection of 7kV for human body model, 8kV for IEC61000-4-2, and 5kV for charged device model. In addition, it boasts a very fast response time of less than 1ns.

In terms of application field, the MXSMCJ28CA is commonly used in digital visual interface (DVI) signal lines, USB 2.0, single-ended and differential data signal line protection, and any other hardware that require surge protection. The main purpose of this product is to protect electronics from electrical spikes brought on by electrostatic discharge and other forms of electricity.

The working principle of the MXSMCJ28CA is pretty simple. It is designed to limit the voltage across sensitive electronics during the surge. When the high-amplitude waveform occurs, it will be broken down by the device, clamp the voltage, and then dissipate the excess energy. It is this excess energy that is responsible for causing damages to the device like surges, spikes or over-voltage.

The MXSMCJ28CA TVS diode offers effective protection in the harshest environments, and provides low-capacitance in order to not interfere with any desired signal. It is also easy to install, and can fit in a wide variety of applications. The combination of its effective protection and reliable performance makes it one of the favorite choices for today’s high-speed applications.
