MMBZ5225B-E3-18

Introduction

MMBZ5225B-E3-18 is a part of the single Zener diodes. It is manufactured by ON Semiconductor with a total power of 0.25Watts. It allows a reverse current from 3V to 18V with a voltage drop of 62mV at a rated 75mA power.

Application Field

MMBZ5225B-E3-18 can be used for a variety of applications. In the industrial sector, it can be used for noise reduction, voltage regulation, and circuit protection. For example, it can be used to limit the voltage across an LED, from a power source, in a lighting control system. The MMBZ5225B-E3-18 can also be used in audio and RF circuits to ensure stable output levels.

In the electronic industry, the MMBZ5225B-E3-18 can be used as a level shifter, voltage supervisor or noise suppressor. The diode has a low reverse current leakage and can be used for precision current limiting and voltage regulation in complex circuit designs. The low reverse current allows for a highly-accurate regulation even when subject to higher currents or temperatures.

Working Principle

The MMBZ5225B-E3-18 works in the same way as other ordinary diodes. It is a two-layer chip which allows current to either flow or not between the two layers based on the voltage applied across the two diodes (anode-cathode). The diode functions with a reverse current by blocking current in the reverse direction, but when the connection is in the forward direction (from anode to cathode) it allows current to flow.

When the voltage across the diode is between 3V and 18V, the MMBZ5225B-E3-18 works in zener mode. It limits the voltage by passing a low amount of current until the voltage reaches the zener breakdown. The current passing through the diode is proportional to the voltage applied. This device offers a regulated and safe flow of current even when subject to higher power or temperature. It also offers high-temp stability and low zener impedance.

Conclusion

MMBZ5225B-E3-18 is a part of single Zener diode. It features a total power of 0.25 Watts, reversing current from 3V to 18V, and a voltage drop of 62mV at 75mA power. It can be used in different applications including industrial purposes, level shifting, and circuit protection. In addition, it works by blocking current in the reverse direction, and allowing it to flow in the forward direction when the voltage between the two diodes is between 3V and 18V, in the zener mode.
