TVS or transient voltage suppression diodes are devices that protect sensitive electronics from high voltage, sudden discharges of current commonly known as transients. The MXSMBJ16CA is a TVS diode with a very low diode capacitance and a high surge rating that has become the go-to device for automation and data transmission applications. It is also used in other industrial and consumer electronics applications such as LED lighting, cell phones, automotive ECU, and home appliances.

The MXSMBJ16CA is a low-capacitance, unidirectional symmetrical diode with an improved inverse current rating of 600W peak pulse power rating at 8/20 μs and 10/1000 μs pulse widths. Its breakdown voltage is 16V (minimum 12V for IEC 61000-4-2), and its maximum clamping voltage is 27V. It provides protection to up to 120VAC Industrial, IEC 61000-4-2 events without extra components.

The TVS diode is constructed out of a Zener diode in series with an avalanche diode, which creates a very short stagnation voltage drop when exposed to an over-voltage spike. This prevents the voltage from rising to a level that will damage sensitive components connected to it. The MXSMBJ16CA leverages this design to offer superior capability and performance.

The MXSMBJ16CA features a very low capacitance of only 2.5pF (typical), allowing it to be used for applications that require very fast response times. It also features a high surge capability of 18A (8/20 μs) and 35A (10/1000 μs), making it ideal for use in applications with high levels of transient voltages from lightning, electro-magnetic interference (EMI), or other sources.

The MXSMBJ16CA’s low capacitance and high surge capability make it ideal for use in communications and control systems. In data transmission applications, the diode’s low capacitance allows for very fast signal transitions, which reduces the amount of distortion and interference from noise. In automation and control systems, the MXSMBJ16CA’s high surge capability provides additional protection from electrical surges, which can cause damage to sensitive components.

The MXSMBJ16CA provides a cost-effective and reliable solution for protecting sensitive electronics from transient voltages. Its very low capacitance and high surge capability make it the ideal choice for many applications, from data transmission and control systems, to consumer electronic devices and home appliances.
