SMCJ26CA-M3/57T is a TVS-diodes consisting of a diode-connector in which the diode structure is a discrete, ultra low-capacitance, low-capacitance, low-leakage ESD protection diode. It is designed for use in protecting applications sensitive to Electro-statically Discharge (ESD) and electrical overstress protection, as well as for providing applications with a degree of electrical noise reduction.  The SMCJ26CA-M3/57T is composed of a diode and its necessary external circuit connections, forming a single terminal device. Construction is optimized for low-capacitance, high-frequency, low-voltage ESD power supply backup applications. The main application for the SMCJ26CA-M3/57T is as a surge suppressor in automotive, industrial and consumer applications. It can be used in automotive alternators, backup systems, protection of antenna ports, electronic control units (ECUs), motor controllers, and consumer power supplies and device connectors.The working principle of the SMCJ26CA-M3/57T is to provide electrostatic discharge (ESD) protection by shunting the transient voltage to ground. This protection is provided through a wide dynamic range, allowing the diode to act as an effective ESD protection structure. When a transient voltage applies to the diode, the diode captures the voltage, conducts it to ground, and dissipates it as heat energy. During operation, the diode effectively reduces the voltage levels and changes the wave shape from overvoltage levels to within acceptable voltage limits. In some cases, it is also possible to attenuate ESD transients to harmless levels.Additionally, the SMCJ26CA-M3/57T has a good high-frequency response and low capacitance, allowing for good noise reduction. This is especially important in systems where the risk of signal integrity loss due to interference is present. In summation, the SMCJ26CA-M3/57T diode is an excellent device for ESD and electrical over-voltage protection in a variety of applications. Its low capacitance and effective clamping result in a very reliable, low loss, and low noise diode that can provide solid protection for sensitive devices and systems.
