MUR2505 is a schottky rectifier diode designed to limit the reverse recovery time of the diodes and provide high forward surge current capabilities. The high speed and low forward voltage drop of this discrete technology makes the MUR2505 a perfect application for battery charging, automotive and industrial systems.

MUR2505 diodes are mainly suitable for AC-DC, DC-DC and pulse applications, DC power supply, low power electronics and light fixtures. The diode’s rugged construction and fast reverse recovery time makes them ideal components for high-frequency switching circuits such as solar cells, switching regulators, and DC to DC converters.

The MUR2505, like all Schottky diodes, has anode and cathode terminals which are made from a combination of materials including a metal and a semiconductor. The metal acts as the anode and the semiconductor the cathode. When a voltage is applied between the two terminals, current will flow from the anode to the cathode and the diode will allow current to flow unidirectionally only.

In terms of resistance, the MUR2505 rectifier diode is a low-resistance semiconductor device. It has a typical forward voltage drop of 0.45 volts. The forward surge current specification is 7A at 20µsec and the reverse recovery time is 40nsec. The device specified operating temperature range is -55°C to +125°C.

The most important factor to consider when applying these MUR2505 diodes is the heat dissipation. Designers should ensure sufficient air flow and heat sinking of the device to create a proper working environment and enable reliable operation over the intended temperature range.

In order to maximize efficiency and enable the diode to survive any surge or reverse spike current, a flyback diode should be placed across the load along with the Schottky diode. This will protect against any accidental high current conditions.

The MUR2505 is an ideal device for any application requiring high-level accuracy, reliable operation and fast switching capabilities. Its small size and fast forward recovery time make it an ideal component for any power switching system, or for any industrial or automotive application.
