SMBJ20A-13

The SMBJ20A-13 is a Uni-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes. It uses the Zener breakdown mechanism to provide overvoltage protection, and is most commonly used to protect essentially DC powered applications from high-voltage transients such as those caused by lightning or high-energy switching. This part of the series is designed to protect components from voltages as high as 20V. Like many TVS diodes, the SMBJ20A-13 is designed to operate within an extremely wide range of conditions including temperature, current, and voltage.

The SMBJ20A-13 is an ideal solution for the protection of components such as switches, relays, and microcontrollers, from overvoltage transients. It can also be used to protect I/O circuits in computers and digital equipment, and any other applications that require overvoltage protection. This TVS diode is designed to clamp transient currents and protect sensitive components from voltage spikes through its Zener breakdown mechanism.

The SMBJ20A-13 features a low and unrestricted current carrying capacity, making it suitable for a variety of applications. Its large surge current capability is also suitable for protecting a multitude of components and circuits from the damaging effects of transient overvoltage. The SMBJ20A-13 can be used in a number of different systems and applications where overvoltage protection is needed, but it is most typically found in automotive and industrial applications.

The working principle of the SMBJ20A-13 is relatively simple. When the device is exposed to a voltage higher than its breakdown voltage, usually increased by an overvoltage transient, it will conduct current. This current is then diverted away from the sensitive components connected to the diode, preventing them from harm. The SMBJ20A-13 clamps the voltage at the breakdown voltage, and all excess current is then dissipated. This process is commonly referred to as Zener breakdown.

The SMBJ20A-13 is a cost-effective and reliable solution for overvoltage protection in sensitive electronic systems. Its low capacitance, large surge current capabilities, and low thermal resistance, make it a highly versatile solution for many different applications. Its compact size also makes it suitable for installation in tight spaces, making it ideal for a wide range of industrial, automotive, and consumer applications.

In summary, the SMBJ20A-13 is a cost-effective TVS diode designed for use in systems where overvoltage protection is needed. It works by clamping transient voltages at the breakdown voltage and dissipating any excess current. This device is most commonly used in automotive, industrial, and consumer applications, and can be used in a wide range of conditions. The SMBJ20A-13 is a reliable and effective solution for providing overvoltage protection in any application.
