MTZJ4V7SB R0G

Introduction

The MTZJ4V7SB R0G is a Zener diode designed for single applications and is typically used to protect components from transient spikes in low-voltage circuits. This type of diode has the ability to regulate a voltage to a predetermined level and break the circuit should that voltage become too high. Depending on the application, this diode can also be used to reverse the current flow and to protect circuits from any type of fault current.

Working Principle

The working principle of MTZJ4V7SB R0G is based on breakdown voltage in Zener diodes. This type of diode utilizes a semiconductor p-n junction. The traditional semiconductor p-n junction is known to be affected by applied voltage. The voltage drop across it transcends the barrier height, allowing the two semi-conductors to be in contact and generate current flow.

In the MTZJ4V7SB R0G, the applied external voltage is higher than the breakdown voltage, which results in an increase in the electric intensity of the junction. This causes Zener breakdown, which activates an avalanche effect that further enhances the current flow in the system. As the current increases, the applied voltage increases as well and the impedances across the diode drop to zero, allowing for a continuous current flow.

Typical Characteristics

The MTZJ4V7SB R0G has a breakdown voltage of 6.2V - 7.2V and a maximum zener impedance of 5.0 ohms. The diode also has a typical thermal resistance of 20oC/W. The typical forward current of the diode is 2.0A. In terms of power dissipation, the diode can handle up to 500mW.

Application Fields

The MTZJ4V7SB R0G is a versatile device that can be used in a variety of low-voltage circuits. It can be used to protect against transient spikes in systems such as electrical motor controllers, as well as for reverse current and insulation/protection circuits. In addition, the diode can be used in ripple control, optical equipment, isothermal control, and audio/video equipment.

Conclusion

In summary, the MTZJ4V7SB R0G is a diode designed for single applications and is typically used to protect components from transient spikes in low-voltage circuits. The diode works by utilizing breakdown voltage in Zener diodes with a breakdown voltage of 6.2V - 7.2V and maximum zener impedance of 5.0 ohms.
