MURD340T4

Diodes - Rectifiers - Single

MURD 340T4 is a single diode rectifier, a semiconductor device commonly deployed in power supply applications. Diodes are devices that allow current or electricity to flow in one direction only and block its flow in the opposite direction. This action is referred to as rectification. Rectification is what enables voltage to be converted from AC or Alternating Current to DC or Direct current.

Full Wave Rectification

The MURD 340T4’s application field is around full-wave rectification. This type of rectification requires two diodes connected in series in order to convert an alternating current into direct current. This is often used in power supply applications where AC voltage is converted into DC voltage to be used by an electrical device.

The two diodes act in opposite phases of the input alternating current cycle, allowing current to flow through the circuit and providing the desired DC voltage output.

Working Principle

The MURD 340T4 works by allowing current to pass through an anode, indicated as "A”, and into its connecting circuit. The current is then blocked when attempting to flow out of the circuit by the MURD340T4 diode, which acts as a barrier at its cathode, indicated as "K”. The design of the diode ensures current will not be trapped in the circuit, as the diode provides a path for current to follow and safely leave the circuit.

The MURD340T4 is designed to withstand high temperatures and retain its properties. Its peak repetitive reverse voltage can be as high as 660V and its peak one direction surge current can be as high as 200 amperes.

The MURD340T4 is an example of a single diode rectifier that is well-suited for power supply applications. Its working principle and application field focused on full-wave rectification makes it a popular choice for converting AC voltage into DC voltage.
