SMF8V5A-E3-18 Application Field and Working Principle

Transient Voltage Suppressor (TVS) diodes are an efficient device to protect electrical and electronic circuits from potential damages caused by transient voltages. They are also known as clamp diodes and consists of crucial components that allow them to protect against electrostatic discharges (ESD), overvoltage transients from power induction, and lightning transients. A SMF8V5A-E3-18 is one type of TVS diode and boasts a capability to dissipate up to 8 Watts of power in applications with a maximum working voltage of 5 volts and an EFT energy of 18 Joules.

The applications of SMF8V5A-E3-18 are numerous and can be found within various industries. This diode is mainly utilized in automotive related and consumer electronics such as navigation systems, camera modules, and infotainment systems. Additionally, they can be employed in all kinds of batteries including secondary, solar, industrial, and medical.

Working Principle

TVS diodes basically act like a short circuit once a surge or spike of voltage reaches a certain predetermined level. This is brought about by the junction breakdown component of the SMF8V5A-E3-18. The voltage relating to the breakdown event of the diode is known as its breakdown voltage or Vbd. When the surge voltage is equal to or higher than the Vbd of the diode, a large quantity of electric current flows through the diode, discharging the source quickly and harmlessly.

The voltage clamping effect of the SMF8V5A-E3-18 is also essential to protect the circuit against excessive voltage. In cases of a voltage spike, the diode will simply reduce the voltage clamping the peak voltage level and limits the current. The diode then absorbs the excessive voltage and energy in the form of heat and dissipates it outwards. This protects the connected equipment from damages thus ensuring its long life.

Ultimately, SMF8V5A-E3-18 devices are effective, reliable, and cost-efficient solutions to secure electrical circuits from potential voltage transients, ensuring safety as well as the long-term performance of the system.
