The SMF51AHRVG is a unidirectional Transient Voltage Suppressor (TVS) Diode array component that is designed to help protect electronics from voltage and current transients. It is a low-cost component that works according to the principle of suppression of over voltage or over current impulses.

The SMF51AHRVG TVS diode array consists of 4 diodes connected in series with a common cathode connection. It is typically used in applications such as IC protection, and protection from secondary over voltage transients from the primary power rail. The component is rated for 55V Breakdown Voltage (BV) with the internal diode junction voltage at 70V. It has a power dissipation rate of 120W, and a responses time of less than 1 nanosecond.

The SMF51AHRVG TVS diode array is well suited for applications in consumer, industrial, automotive, telecommunications, and other markets. It can be used in circuits to protect low voltage and high speed ICs from over current and over voltage, and ESD damage. It is also suitable for use in AC/DC transient pulse suppression circuits, in order to protect circuits from destructive over voltage transients. The SMF51AHRVG TVS Diode array is also suitable for various military and aerospace applications.

The working principle of the SMF51AHRVG TVS Diode array is based on a combination of avalanche breakdown and Zener effect. When over voltage or current impulse is supplied, the internal diode junction voltage across the SMF51AHRVG component starts to increase. If this voltage is higher than the breakdown voltage, the diode will start to avalanche, resulting in a low impedance sink for the applied voltage.

The avalanche effect of the SMF51AHRVG TVS diode array allows for a very quick response time, typically less than 1 nanosecond. This allows the component to effectively suppress over voltage and current transients, thereby protecting the underlying electronics from damage. Additionally, the device can be used in AC/DC transient pulse suppression circuits, allowing it to suppress transients in both AC and DC power systems.

In summary, the SMF51AHRVG TVS Diode array is a cost-effective component that is well suited for a wide range of applications in both AC and DC power systems. It is a low power component that works on a combination of avalanche breakdown and Zener effect to suppress over voltage and current transients. This makes it well-suited for use in a variety of consumer, industrial, automotive, military, aerospace, and telecommunications applications.
