Working Principle

The SMAJ4749CE3/TR13 works on the concept of Zener breakdown. When a voltage is applied to the component, the electrons in the conduction band of the device will get accelerated across the junction and a current should flow across the component. When the applied voltage reaches a certain limit, known as the Zener voltage, the current flow quickly increases in a phenomenon known as Zener breakdown. This sudden increase in current, which is accompanied by a decrease in voltage, is what helps to regulate and protect circuits from voltage spikes.

Conclusion

The SMAJ4749CE3/TR13 is a single zener diode component which is used in a variety of applications and industries. It helps to regulate the voltage in electrical and electronic devices, and also helps to protect circuits from sudden spikes in voltage. It works on the phenomenon of Zener breakdown, where a sudden increase in current is accompanied by a decrease in voltage, helping to protect circuits from voltage spikes.
