MUR2540 is a diode and rectifier device in the form of a single, axial leaded, add-on package. It is a part of a larger range of rectifiers and diodes and is developed especially for applications in the heavy industrial and automotive sectors and is ideal for applications where there are high shock and vibration levels. The device can operate temperatures of up to 150°C and has a low forward voltage drop of 1.1V.

MUR2540 features a stud cathode and cathode pin connections, allowing fast assembly and secure connection to the circuit board. The diode is designed to withstand high surge forward and reverse currents while cutting off reverse voltages. It is also designed to be highly resistant to surge currents, making it an ideal diode and rectifier device for applications with high power requirements.

The MUR2540 has a wide operating temperature range of -40°C to 150°C and an effective power rating of 1.3kW, making it a reliable device for applications that require high current or power. It also has a breakdown voltage rating of 600V. The device is capable of handling peak reverse voltage of up to 400V and a peak forward current of 1.5A.

MUR2540 is a surface mounted device, with a slim profile that enables high density board layouts. The device is highly stable under varying temperatures and is self-limiting, meaning that its electrical resistance remains constant over a range of current and temperature values. This device also features fast reverse recovery time and excellent junction temperature. Additionally, it can withstand multiple reflow soldering cycles, offering reliability and repeatability.

The MUR2540 device is suitable for both commercial and industrial applications. It is widely used in automotive lighting systems and power supplies, residential and commercial lighting, industrial motors and generators, solar power systems, and power adapters. The device is also used in AC/DC and DC/DC power supplies, and has been tested and verified in applications such as motor control, solar power, and lighting.

The working principle of the MUR2540 is based on junction technology and it forms a diode bridge rectifier. The device has a forward biased PN junction and a reverse biased PN junction. When a voltage is applied to the PN junction, current begins to flow in the forward direction causing the diode to conduct and the output voltage to be rectified. As the voltage applied to the PN junction exceeds the threshold voltage of the diode, the diode becomes fully forward biased and can withstand a peak reverse voltage of up to 400V.

When the PN junction is forward biased, the rectified output is known as the half-wave rectified voltage. The rectification of the output voltage takes place when the input voltage is greater than the threshold voltage of the diode and the output voltage is double the input voltage. This double voltage rectification is known as the full-wave rectification.

The MUR2540 diode and rectifier device is an economical and reliable choice for applications that require high current or power, as well as those that require fast setup times and secure connection to the circuit board. The device has a wide operation temperature range and is highly stable under varying temperatures and can withstand multiple reflow soldering cycles for repeatability. Its low forward voltage drop and high surge forward and reverse current capabilities make it an ideal choice for automotive, residential, and commercial lighting, and power adapter applications.
