TVS - Diodes

TVS (transient voltage suppressor) diodes have been around for decades, but their popularity in the modern era has skyrocketed due to the increasing prevalence of electronic devices in day-to-day life. Benefits of using these diodes include the protection of sensitive components from power surges and protection from electro-magnetic interference (EMI). One of the most widely-used TVS diodes is the SMBJ24A-TP, which offers a wide range of useful features.

Applications of the SMBJ24A-TP

The SMBJ24A-TP diode is used extensively in a variety of industries and products. It is a primary component in the protection of circuit boards from line transients and peak operating voltages. The device has been designed to be compatible with the most common logic families and provides low capacitance to suppress ringing and reduce the probability of a false switching event. In addition, it is suitable for circuits requiring ESD protection, power cross-protection, and lightning rectifications. Since the device has a low maximum operating voltage, it is also an ideal choice for protecting circuits from surge voltages.

The SMBJ24A-TP diode is often used in the protection of consumer electronics, such as game consoles, cell phones, tablets, and computers. It is also used in a wide variety of automotive electronics, such as airbag systems, engine control systems, and ABS systems. Finally, the SMBJ24A-TP is frequently used in the telecommunications, industrial, and aerospace industries.

Working Principle of the SMBJ24A-TP

The working principle of the SMBJ24A-TP diode is relatively simple. It consists of two p-n diodes connected in "back-to-back" orientation. This structure creates a highly symmetrical, two-terminal structure which is able to protect against transient voltage disturbances. When a voltage perturbation (surge, transients, etc) is applied to an input circuit, the diode responds by dissipating the excess energy to its outputs at a much lower voltage level than that of the input. As the diode responds to the voltage perturbation, it behaves as an "open-circuit" and does not allow a flow of current to continue flowing in the circuit. This preventative measure effectively stops the surge from further damaging the circuit.

The SMBJ24A-TP diode is also designed to have a low capacitance, which helps to reduce the possibility of false switching events. The device is capable of suppressing transients up to 150W peak pulse power (10/1000µs waveform). This makes it an ideal choice for use in a wide range of power distribution systems, as well as in consumer electronics.

Conclusion

TVS diodes are an essential component in the protection of electronic circuits. The SMBJ24A-TP diode from BSMCN offers a wide range of useful features, including a low capacitance, low maximum operating voltage, and the ability to protect against transient voltage disturbances. This makes the SMBJ24A-TP diode an ideal choice for use in consumer electronics, automotive electronics, power distribution systems, and other applications requiring reliable surge and transient protection.
