The SMAJ28A-13 is a popular type of transient voltage suppressor (TVS) diode. It is a unidirectional component that offers a high surge protection against transient voltages. It is used in a wide range of applications, including protecting electrical circuits from damage caused by electrical surges. In this article, we will take a closer look at the application field and working principle of the SMAJ28A-13.The SMAJ28A-13\'s application field covers a wide range of industries, including automotive, telecommunications, aerospace, and consumer electronics. It is designed to provide efficient protection against fast and slow transients and can be connected in both series and parallel configurations. It can be used both as a stand-alone device and within larger protection assemblies.The basic working principle of the SMAJ28A-13 is similar to that of other TVS diodes. It has two distinctly different roles in protecting a circuit. The first role is to clamp high voltage transients, while the second role is to dissipate fast and slow transients. When a high voltage transient enters the circuit, the diode will clamp it to a predefined threshold voltage. This limits the current flow and prevents it from damaging the sensitive elements of the circuit.The device also acts as a resistor when there are slow transients, allowing some current to flow. The peak current flow is limited by the measured transient voltage and the junction capacitance of the device, by a mechanism called "avalanche breakdown". When a fast transient enters the circuit, the avalanche breakdown mechanism dissipates the energy, protecting the circuit from damage.The SMAJ28A-13 is designed to provide protection against both fast and slow transients up to a rated voltage of 14 volts. The device is highly reliable and capable of handling surge currents up to 5kA (8/20uS). It has an operating temperature range of -65°C to +175°C and a storage temperature range of -55°C to +175°C.Overall, the SMAJ28A-13 is a dependable and cost-effective solution for protecting sensitive electrical circuits from transient voltages. It is highly reliable and offers a wide range of protection capabilities for different types of transient conditions. It is designed for use both in series and parallel configurations, making it a versatile and attractive choice for applications that require surge protection.
