BZG03C16-HM3-18 Application Field and Working Principle

The BZG03C16-HM3-18 is an individual Zener diode specifically engineered for applications where the tightest regulation and excellent temperature stability are desired. This diode provides a voltage regulation in the range of 3.3 volts due to the very low maximum voltage 2.8V. It can be used to protect sensitive electronic components from excessive run over voltages and consequent destruction by maintaining a regulated output voltage.

• Data communications
• Telecommunications
• Industrial control systems
• Consumer electronics

Working Principle

The BZG03C16-HM3-18 functions as a Zener diode. When working as a Zener diode, it is connected with the anode and cathode towards a single direction and no regular voltage is applied to the diode. However, when a voltage is applied from the anode to the cathode greater than the Zener breakdown voltage, the diode will start conducting and will limit the voltage across the diode to the Zener voltage.

The BZG03C16-HM3-18 Zener diode itself is a type of diode that operates reverse biased, and it is made to contain a thin lightly doped p-type region between its n-type layers. This thin lightly dopedP-type layer allows electric field concentration when enough reverse voltage is applied, hence resulting in a Zener breakdown. This Zener breakdown turns the diode conductive, resulting in the diode clamping the bridge voltage to the diode\'s Zener voltage.

Furthermore, the BZG03C16-HM3-18 Zener diode typically operates in the forward-biased region during normal operation. During this region, a small reverse current will flow through the diode, typically required for regulating its voltage accurately. This leakage current is known as the Zener current.

Since the BZG03C16-HM3-18 is specifically engineered for applications where tight regulation and excellent temperature stability are required, the diode has a tight tolerances for Zener voltage and leakage current. Its Zener voltage is ±2.2mV between -55°C and +125°C, which means that the diode will be able to maintain its regulated output voltage in both hot and cold temperature conditions.

Conclusion

The BZG03C16-HM3-18 is a Zener diode specifically engineered for applications where tight regulation and excellent temperature stability are desired. It features an excellent flicker noise immunity, very sharp temperature coefficient, high regulation accuracy, and low power consumption. It is primarily used in data communications, telecommunications, industrial control systems, and consumer electronics. When functioning as a Zener diode, the BZG03C16-HM3-18 will create a Zener breakdown to turn the diode conductive and clamp the bridge voltage to the diode\'s Zener voltage. With its tight tolerances for Zener voltage and leakage current, the diode will be able to maintain its regulated output voltage in both hot and cold temperature conditions.
