TVS - Diodes are an important component of an electronic circuit which are used for protecting the valuable component from energy spikes or high voltage transients.

A SMBJ9.0A-E3/5B is a type of TVS (Transient Voltage Suppressor) diode which is specially designed for ensuring the safety of the circuit in high voltage applications.

The SMBJ9.0A-E3/5B is a unidirectional device which is capable of dissipating up to 10W peak pulse power in the typical applications. It provides ESD (Electro-Static Discharge) protection in accordance with IEC 61000-4-2 standards. Also, it provides over-voltage protection to the valuable component in the circuit from voltages exceeding the maximum rated value. The device is operated at FEP (Forward Voltage Experience Integrity) and has a surge capability 15A (8/20 μs).

The SMBJ9.0A-E3/5B is best suited for use in circuitry to protect them against high voltage transients and power surges. The device can be mounted on board or in a socket, and it is suitable for reflow soldering. It is available in a variety of voltage ratings from 6.0V to 400V.

The working principle of the SMBJ9.0A-E3/5B is as follows: The diode is placed across the source of the high voltage transient and acts as a short between the two points. The diode then quickly breaks down when the voltage across it exceeds the maximum rated value, thus diverting the energy spike away from the system. This is done to protect the system from any harm due to the energy spike.

In conclusion, the SMBJ9.0A-E3/5B is an ideal component for high voltage applications as it ensures the safety of the circuitry by providing temporary protection against voltage and power surges.
