SMBJ7.0CD-M3/I Application Field and Working PrincipleTVS diodes, also known as transient voltage suppressors, are semiconductor devices used to limit the voltage, current or power of a given circuit. These devices usually have two terminals, one of which is used to permit very low currents to pass while the other prevents higher voltage from entering the circuit. As such, they are used to protect sensitive devices from transients like surges, spikes, and excessive voltages. The SMBJ7.0CD-M3/I is a unidirectional TVS diode manufactured by Vishay, a major world manufacturer of electronic components. This device is widely used in automotive, communication, and consumer electronics applications that require transient voltage protection. In automotive applications, the SMBJ7.0CD-M3/I is ideal for protecting ECUs, communication lines, and other sensitive electronics from transients caused by electrostatic discharges, engine backfires, and unexpected power drops. Due to its low capacitance and low leakage, it is well-suited for data line protection in cars. It is typically used in the power lines of automotive power systems as well as in car audio systems to protect tweeters, mid-woofers, and other sensitive components from voltage spikes. In communication applications, the SMBJ7.0CD-M3/I is usually used in Ethernet line networks to protect high-speed data transmission from transients and voltage surges. The working principle of the SMBJ7.0CD-M3/I revolves around reverse breakdown voltage. The device has two terminals: an anode and a cathode. When a transient voltage is applied across its terminals, the voltage on the anode side increases above the normal level, triggering a sudden flow of electrons between the anode and the cathode. This reduces the voltage on the anode side to a safe level, effectively protecting the connected electronic components from permanent damage. In summary, the SMBJ7.0CD-M3/I is a unidirectional stateof-the-art transient voltage suppressor (TVS) diode that can be used in numerous automotive, communication and consumer electronics applications. Its working principle is based on reverse breakdown voltage, which allows it to protect connected components from transients, spikes and excessive voltages.
