Diodes - Rectifiers - Arrays

The 403DMQ100 is a diode array, made up of four individual silicon diodes connected in parallel. It is designed for use in applications such as motor control, high voltage battery protection, AC/DC converters, and switching power regulators. The main purpose of this part is to provide high-speed switching power conversion and protection against overvoltage conditions.

Design and Components

The 403DMQ100 is a four-anode diode array made up of four individual one-pole diode devices. Each device has two pins, a common anode and a cathode. It is rated for a voltage of 400V and a sustained reverse current of up to 10mA. Its dimensions are 1x2x3.8 mm.

The 403DMQ100 is made up of individual non-polarized polysilicon diodes which are connected in parallel. This allows for a high current capacity – up to 1A – with no increase in voltage drop or power loss. The diode array also provides very fast switching times and low-power operation.

Application Field and Working Principle

The 403DMQ100 is used in applications where a high speed switch is required and/or overvoltage protection is necessary. Common uses of this diode array include motor control, AC/DC converters, switching regulators, and battery protection.

The 403DMQ100 operates on the principle of forward bias. When the anode is connected to a voltage source, electrons flow into the diode structures in a nondirectional manner, and this causes the diode to become forward-biased. This allows current to pass through and form a current path between the anode and the cathode. When the voltage across the diode reaches a certain threshold, the diode starts to conduct current and the switch is open.

At reverse bias, the diode is forced into a non-conducting state and acts as a protector against overvoltage conditions. It is this reverse-bias feature provides the diode array an effective protection against overvoltage conditions by limiting the voltage to a safe level.

The 403DMQ100 is also used in LED TV and LED lighting applications. In these applications, it provides a superior erodibility, high switching frequency and high switching current capacity. It is also used as a protection device in AC/DC converters.

Advantages of 403DMQ100 Diode Array

The 403DMQ100 diode array offers several advantages compared to single diodes or multiple diodes connected in series. Firstly, it provides high current capacity of up to 1A, with low voltage drop and power loss. Secondly, it can provide quick response time and low power operation. Finally, it is able to protect against overvoltage conditions with its reverse-bias feature.

The 403DMQ100 diode array is an ideal part for applications that require high-speed switching and protection against overvoltage conditions. It can be used in motor control, AC/DC converters, switching regulators, battery protection, and LED TV and LED lighting applications.
