Working Principle of SMAJ4749E3/TR13

The SMAJ4749E3/TR13 is a Zener diode, which is a component that conducts electricity in one direction when forward bias is applied, and in the reverse direction when the reverse bias is applied. It works on the tunneling principle, which means that electrons jump through the so-called \'potential barrier\', which appears when a voltage is applied across a diode. The diode then acts as a regulator and regulates the current, preventing it from exceeding the voltage rating of the diode.

When a reverse bias is applied to the diode, the electric field created by it creates a tunneling effect which causes the electrons to move through the barrier. This creates a voltage drop across the diode, which is known as the \'Zener voltage\'. This voltage is used to help maintain the voltage across the diode as constant, thus providing a stable current. This is the working principle of a Zener Diode.

Conclusion

The SMAJ4749E3/TR13 is a single Zener diode commonly used for various applications such as power supplies and portable electronic devices. It has a reverse voltage of 47 volts and a forward voltage of around 1.1 volts, with a maximum operating temperature of 175°C. The Zener diode works on the tunneling principle and regulates the current when a reverse bias is applied. This ensures a stable flow of current and voltage, thus providing a stable output.
