MMBZ5256BLT1G application field and working principle

Introduction

The MMBZ5256BLT1G is a low power zener diode developed by ON Semiconductor. It is a package of a single diode with a voltage rating from 2 to 200 V and a power rating of 0.5W. This diode can be used in many applications, from low-power regulated power supplies to high-voltage protection.

Application fields

The most common application for the MMBZ5256BLT1G is as a shunt regulator for low-voltage power supplies. By connecting the diode across a voltage load, the voltage is regulated to the desired level. This makes it an ideal choice for low-voltage regulated power supplies in consumer electronics, medical and automotive applications.

The MMBZ5256BLT1G can also be used as a voltage reference. By connecting the diode in series with a load, a precise reference voltage is obtained. This is commonly used in operations amplifiers and adjustable circuits.

The MMBZ5256BLT1G can also be used as a protection device. It is often used in devices such as power supplies, which require protection from overvoltage and transients by limiting the voltage. The zener diode has a reverse breakdown voltage, which prevents excessive voltage from traveling further into the circuit.

Working Principle

The MMBZ5256BLT1G is a low-voltage diode and uses a simplified version of the PN junction. In this structure, the forward voltage drop is approximately 0.7V. When the reverse voltage increases beyond 6V, the zener effect comes into play, whereby the voltage across the diode is limited to a predetermined value.

In addition, the MMBZ5256BLT1G diode also has a low dynamic resistance, which enables it to respond quickly to changes in voltage. This property makes it an ideal choice for protection and regulation circuits, as it can quickly limit the voltage when the applied voltage exceeds a certain threshold.
