What is SMC5K16A-M3/I?

SMC5K16A-M3/I is a TVS (Transient Voltage Suppression) diode which is designed to protect a circuit or component from high voltage or high energy transient overvoltage. It is able to handle a wide range of voltage or energy transients, ranging from 5V to 36V. It is also able to handle extremely high power pulses up to 5 kiloamps, making it very versatile and suitable for a variety of applications.

Application Field of SMC5K16A-M3/I

SMC5K16A-M3/I is ideally suited for use in applications such as automobiles, industrial equipment, and other consumer appliances. It is especially suitable for applications where transients occur frequently such as in power converters or switching power supplies. This diode is also well suited for electrical and electronic circuits that use IGBTs or MOSFETs. Its low capacitance and high dV/dt rating make it ideal for situations where high frequency switching is required.SMC5K16A-M3/I can also be used in circuit protection applications such as protecting against electrical overstress due to load changes, device longevity, and electrostatic discharge protection. It is also ideal for transient voltage suppression in automotive electronic control units, airbag systems, and other safety critical applications.

Working Principle of SMC5K16A-M3/I

The main purpose of the SMC5K16A-M3/I is to protect a circuit or device from overvoltage transients. It works by automatically clamping the voltage during a high energy transient. When the voltage exceeds the diode\'s breakdown voltage, the diode\'s internal avalanche breakdown process starts. This process rapidly conducts any high energy transient back through the diode\'s anode-cathode junction, thus limiting the voltage at the anode to a safe level.When the voltage reaches the diode\'s peak power and current rating, the diode becomes saturated and starts to "open up", dissipating the excess current and preventing it from entering the circuit. When the transient has passed, the diode recovers and the voltage in the circuit returns to normal.

Conclusion

The SMC5K16A-M3/I is a great solution for a number of applications requiring protection from transient overvoltage. It is ideal for applications where power converters and switching power supplies are used, as well as for general circuit protection applications. This diode is very reliable and is well suited for a variety of applications due to its wide range of voltage and energy transients, high-dV/dt rating, and low capacitance.
