MTZJT-7230B

Diodes - Zener - Single

MTZJT-7230B is a typical Zener diode. It is mainly composed of a PN junction. It is a kind of overload protection element under the category of sand diodes, and also belongs to semiconductor devices.

The MTZJT-7230B Zener diode belongs to the 3.3V voltage regulator, and its maximum reverse breakdown voltage is 3.3V. Its working principle is very simple, under normal pressure, the current is blocked, and when the voltage is higher than the voltage of the Zener diode in the reverse direction, the Zener diode will be inversely conducted, the current flows from its cathode to its anode, and the voltage maintains at its reverse breakdown voltage, that is, the Zener breaks down in this zone.

The application field of MTZJT-7230B mainly includes power supply voltage stabilization, protection circuit, and voltage regulator. It is widely used in electronic equipment, computer electronic and military communication.

When the MTZJT-7230B Zener diode is used as a power supply voltage stabilizer, it should be connected in parallel with the load in series with the power supply. When a slight voltage fluctuation occurs in the power supply, the Zener diode can cause conduction and discharge the overload voltage in time, so as to effectively reduce the voltage variation on the load. When the voltage is shorted to prevent the circuit from burning out and protect the equipment, the MTZJT-7230B Zener diode is usually connected in series with the power supply or circuits being protected. During a voltage or current surge, Zener diode will be burnt out, so as to protect the other circuits. When the MTZJT-7230B Zener diode is used as a voltage regulator, its anode is connected with the power supply, its cathode is connected with the regulated circuit, and its two ends should be connected with a stabilizing resistor between its two poles, so as to make the Zener diode function normally.

In summary, the MTZJT-7230B Zener diode belongs to the 3.3V voltage regulator, mainly used in power supply voltage stabilization, protection circuit and voltage regulator. Its working principle is simple, using reverse breakdown to maintain a stable voltage.
