TVS – Diodes are used to protect electronic circuits against over-voltage related damages such as transient voltage spikes and over-voltage transients. The SMBJ20A-Q is a unidirectional transient voltage suppression (TVS) diode that is designed to protect electronic components from transients that can cause significant damage. It is rated for a maximum forward current of 20 Amps (A), peak pulse current of 40 Amps (A) at a working voltage of 20 volts (V).

The SMBJ20A-Q application field includes but is not limited to DC power lines, automotive and industrial power lines, and hundreds of other applications. Its main purpose is to protect electronic components from over-voltage transients, and it is most commonly used to protect automotive electronics, industrial control systems, and in consumer electronics applications. As a TVS diode, it is also widely used to protect against electrostatic discharge (ESD) and to limit the propagation of strong surge events.

The SMBJ20A-Q transient voltage suppression diode works by providing a path for current to drain from high voltage transients. It has a breakdown voltage of 28 volts (V) and a working voltage of 20 volts (V). The TVS diode is designed to protect the sensitive components that may be connected to the DC power lines, automotive and industrial power lines, and hundreds of other applications, as listed above. This particular TVS diode has a low stand-off voltage, which helps to prevent the transients from damaging the sensitive components that are connected to it.

The SMBJ20A-Q is internally heat-sinked, which helps to dissipate the excess power generated by the high current transients. It has a high immunity to over-powering, and it is also insensitive to reverse power. This means that it can be used in applications where there is a risk of back-emf (electromotive force) or reverse power, which could cause damage to the component. This also makes the SMBJ20A-Q ideal for automotive electronics, industrial control systems, and consumer electronics applications where reverse power or back-emf could be a problem.

The TVS diode is relatively easy to install and use, and it does not require any special circuitry to be used. It is usually mounted onto a PCB using standard surface mount technology (SMT). In addition to this, the SMBJ20A-Q is RoHS compliant, which means that it can be used without having any impact on the environment.

Overall, the SMBJ20A-Q is a highly reliable and cost-effective transient voltage suppression diode that is designed specifically to protect electronic components from over-voltage related damage. It is highly suitable for DC power lines, automotive and industrial power lines, ESD protection, surge protection, and more. The SMBJ20A-Q is a reliable and easy-to-use TVS diode that offers a great amount of protection for a wide variety of applications.
