Working Principle of SMBJ5333B/TR13

The SMBJ5333B/TR13 diode is an N-type diode, which means it has two electrodes, an anode and a cathode. When forward biasing, the forward u-shaped curve flows through the diode, allowing current to pass from the anode to the cathode. When reverse bias, the Zener voltage Vz sets the maximum voltage drop at the anode and cathode. This means that the SMBJ5333B/TR13 diode acts as a voltage regulator, offering a stabilized and accurate power source.

During saturation, the diode is reverse biased, meaning that no current will flow through it. The PN junction of the diode is on the anode side, and the anode voltage is the same as the Zener voltage, Vz. This voltage regulation stability is important in the application areas of the SMBJ5333B/TR13 device, enabling it to be used in high-accuracy circuits.

Conclusion

The SMBJ5333B/TR13 diode has a Zener voltage of 5.3V ± 5%, and has a reverse breakdown voltage of 5.5V ± 10%. This allows the device to be used in a wide range of applications and is a suitable choice for applications requiring precision voltage stabilization and voltage clamping. Furthermore, its stability and accuracy are maintained even when exposed to high temperatures.
