MURS105T3G Discrete Semiconductor Products

The MURS105T3G is a single, general-purpose rectifier typically used in power-supply applications. It’s a popular, cost-effective choice and is designed to support commercial, industrial, and consumer applications, among many others. The device’s design allows current to flow in one direction only and is used to convert an alternating current (AC) to direct current (DC).

Operation and Design

To understand the working principle behind the MURS105T3G, one must firstly understand the diode. A diode is an electronic component formed from two p-n junctions and can be thought of as an electrical valve; allowing current to pass in one direction but not in the other.

The MURS105T3G is housed in a 2-pin SOT-23 package measuring in at only 2mm x 1.25mm x 0.85mm. The device’s total forward voltage drop operates at 0.39 volts and its maximum forward-voltage drop holds between 0.55-0.61 volts. Furthermore, the device can withstand a maximum reverse breakdown current between 5-12mA.

The device contains an integrated bypass diode, which allows any reverse current to be handled by the diode without damaging the component. The MURS105T3G is capable of handling up to 105mA of continuous current with a maximum power heat dissipation of 400mW max.

Applications

The MURS105T3G is found in a wide range of applications including power supply, voltage regulation, and reverse-polarity protection. It also finds use in AC to DC rectification and radio frequency (RF) interference suppression.

In power-supply applications, the diode can be used to convert AC to DC at various voltages, allowing the device voltage to match the output voltage requirements of the application. This function of the component is used in UPS systems, home electronic goods and automotive applications.

The component is also used in voltage regulation circuits that ensure the voltage levels remain constant while the current is fluctuating. The component\'s bypass diode also offers reverse-polarity protection, preventing any damage if the device is connected incorrectly.

The MURS105T3G is also used in converter circuits, used to convert AC power to DC power - such as in applications powering low-current electronic devices such as tablets and small laptops.

Finally, the MURS105T3G is widely used for RF interference suppression. It offers protection from radio-frequency noise, which can cause data corruption from exposure to electromagnetic fields.

Summary

In conclusion, the MURS105T3G is a single, general-purpose rectifier used in a range of applications. Its design allows for current to flow solely in one direction and it allows for the direct current (DC) voltage to be equal to the input AC voltage. The device offers ultra-low forward voltage drop, integrated bypass diode, and enhance thermal performance -allowing it to be used in a range of applications, such as power supply, voltage regulation, and RF interference suppression.
