Diodes – Zener – Single

BZG03C11TR3 is a single zener diodes, providing a direct current application in low power requirements. It is a low voltage diodes, outputting 11 volts with a current of 100 mWatts. It is available in SOT-23 package.

Application Field

As the BZG03C11TR3 is a low voltage, low power diode, it is best suited for applications where low power and low voltage is required. Different examples of application include small audio amplifiers, power supplies, electro-mechanical relays, low dropout linear regulators, alongside switching environments.

Because of its low power, BZG03C11TR3 can provide a smoothing capability to prevent voltage fluctuations when applying multiple voltage sources or varying loads in a circuit.This makes them perfect for telecom and wireless applications, as well as applications in other industries that include motor speed, power conditioning and computer power.

Working Principle

When a diode is forward-biased (meaning the diode is connected in the same direction as the voltage source), current flows from the anode (the positive side) to the cathode (the negative side) of the diode. This means that the diode acts as an open switch in forward-biased mode. This forward-biased status is important for both power flow and switching applications.

In reverse-biased mode, electric current flows from the cathode to the anode, which produces a voltage drop known as the “reverse breakdown voltage,” often abbreviated as VBR. VBR depends on the amount of reverse bias voltage applied to the diode, and is an important specification to consider when using diodes. In reverse-biased mode the BZG03C11TR3 behaves as a Zener diode. Because the reverse breakdown voltage is a fixed voltage, the Zener diode is an ideal choice for voltage regulation.

Issues such as leakage current and noise can occur, however, because the Zener diode doesn’t regulate all frequencies equally. High-frequency noises are released from the diode during when the voltage is not reverse-biased (open switch status), leading to cross-talk of signals and noise in lower power systems. The BZG03C11TR3 is designed to minimise these issues.

Conclusion

In conclusion, the BZG03C11TR3 is a low-power, low-voltage single Zener diodes, best suited for applications where low power and low voltage are desired. Its usage is in low dropout linear regulators, smoother power flow, audio amplifiers, power supplies and electro-mechanical relays. It is most suitable among other diodes because of its reduced effect of power leakage and noise.
