Diodes - Zener - Single are an important component in complicated circuits. Generally, they are designed to control the voltage within a certain range. A 2M91ZHB0G diode falls into this family of components. This article will explain the application field and working principle of the 2M91ZHB0G.

Applications

2M91ZHB0G is a Zener diode that is used for voltage regulation purposes, controlling the output voltage in devices like voltage regulators, mains transformers, and batteries. It is also typically employed in power supplies, signal processing and audio circuits. The maximum sustained voltage of this component is 91 V, and the maximum surge voltage limit is 110 V. The device can sustain a maximum power dissipation of 300 mW, and an up to 5.6 V reverse voltage.

Working Principle

In normal operation, a Zener diode allows electric current to flow in one direction while blocking any current to flow in the opposite direction. This is known as a ‘blocking’ operation. This behavior is due to the physical composition of the component, which includes a junction-terminal that separates the two electrodes. When a reverse bias is applied to the component, the built-in junction field blocks the reverse current flow. When a forward bias is applied, it allows current to flow from the anode to the cathode.

When a Zener diode is in an unregulated circuit, the voltage increases to a point when the built-in electric field causes a breakdown of the junction barrier between the two electrodes. This is known as the ‘zener effect’, and results in the control of the output voltage. The 2M91ZHB0G voltage regulator is designed for this very purpose, to limit the output voltage to within a certain range. In this way, the 2M91ZHB0G can be used as a voltage stabilizer or surge protector.

Conclusion

The 2M91ZHB0G diode from the Diodes - Zener - Single family is designed for voltage regulation purposes, controlling the output voltage in devices like voltage regulators, mains transformers, and batteries. Additionally, its conventional ‘blocking’ behavior separates a forward bias from a reverse bias. The unique ‘zener effect’ prevents the output voltage from getting higher than the regulated value. This makes the 2M91ZHB0G diode suitable for various applications in power supplies, signal processing, audio circuits, and other electrical devices.
