Diodes - Zener - Single

The MTZJ11SB R0G is a single zener diode of the standard 1/2 watt series. It has a maximum power dissipation of 500 mW, and a maximum reverse voltage of 11 V. The device has two main application fields, which are the protection of circuits from voltage spikes and the regulation of voltage in power supplies.

Application Field

The MTZJ11SB R0G can be used in circuit protection applications. When large voltage spikes or noise voltage appear, a zener diode can protect other components such as transistor, operational amplifiers, etc. It can also serve as a switch when connected in parallel with a signal line in order to prevent the current from going beyond a certain voltage level.

The diode can also be used in power supply applications. By connecting the diode in series with the line, it is possible to regulate the voltage that is output from the power source. The voltage will not exceed the zener voltage.

Working Principle

When forward biased, the MTZJ11SB R0G behaves as an ordinary diode and primarily passes current in one direction. When reverse biased, the diode will not conduct normally, but will conduct when the reverse voltage exceeds the zener breakdown voltage. At this point, the diode will start to conduct in reverse and pass the current.

When the zener breakdown voltage is reached, the voltage will remain unchanged even if the current changes. This is because the zener diode maintains a constant voltage across the diode and will not allow the voltage to rise (or drop) even if the current increases.

The MTZJ11SB R0G is of the single zener type, which means that it contains one zener diode. It is used in applications which require one controlled voltage source, such as power supplies and circuit protection. It can be used with other diodes in a circuit in order to provide more than one regulated voltage.

Conclusion

The MTZJ11SB R0G is a single zener diode of the standard 1/2 watt series. It has a maximum power dissipation of 500 mW, and a maximum reverse voltage of 11 V. The device has two main application fields, which are the protection of circuits from voltage spikes and the regulation of voltage in power supplies. It behaves as a normal diode under forward bias, but will conduct when the reverse voltage exceeds the zener breakdown voltage. This allows the diode to regulate a voltage across the diode and hold it at a constant level.
