FR12MR05

Diodes - Rectifiers - Single

The FR12MR05 is a single Rectifier Diode module. It is a low-profile silicon device, ideal for use in high-density surface mount applications. These rectifier diodes are used to convert Alternating Current (AC) to Direct Current (DC). It is a two-terminal device with a positive (anode) and negative (cathode) end. When a voltage south of its rated value is applied at the anode, the diode will conduct and produce current flow through the device. When a voltage is applied exceeding its rated value, the diode will not allow current to flow, thus becoming an open circuit.

The FR12MR05 is composed of two separate single rectifier diodes contained in an integrated package. The two anodes are connected together and the two cathodes are connected together. This allows the device to provide higher current flow than one single rectifier whereas it eliminates the need for multiple separate diodes.

Applications

The FR12MR05 can be employed in a large array of applications. Some of the applications that these diodes can be utilized in include:

• DC-DC converters
• Battery chargers
• DC input systems
• Switching controllers
• Current regulators
• High-efficiency motors
• Dynamic brake circuits
• Heater controls

Features and Benefits

The FR12MR05 features several benefits that makes it a prime choice for rectifying AC to DC current. Some of these features include the following:

• Compact size and low profile
• A wide operating temperature range
• High surge forward current capability
• High current forward rectification capability
• Low forward voltage drop
• High current reverse rectification capability
• Lower reverse leakage current
• Easy installation

Working Principle

The FR12MR05 works on the principle of PN junction diode. When a voltage is applied across the device, the anode will become positively charged, while the cathode will become negatively charged. A voltage that is south of the rated voltage of the diode will be allowed to pass through, while a voltage higher than the rated voltage will not be allowed to pass through. This is because the PN junction will become an open circuit when a positive voltage is present on the anode.

The FR12MR05 is also designed to provide high current rectification capability. This is because of the two separate diodes are connected together in a single package. This causes the diode to provide a higher current flow which can be used for a variety of applications.

The FR12MR05 is a great choice for applications that require reliable rectification due to its high current and low leakage capability.
