3N246-E4/72

Diodes - Bridge Rectifiers

A bridge rectifier is an arrangement of four diodes in the form of a bridge, so that two diodes are connected in series for each polarity of the input voltage and can be used for AC/DC conversion. The 3N246-E4/72 is a bridge rectifier used for power-supply applications where enhanced voltage spike alertness is desired. It features high surge current and temperature capability, low forward voltage drop, automotive temperature range, and ceramic fusing.

Application Field

The 3N246-E4/72 bridge rectifier can be used in several different applications such as in power supply and switching power supplies. It is also used in automotive power systems such as power window motors, wiper motors, and start/stop mechanisms. In addition, it can be used to provide motor control in appliances such as refrigerators and washing machines, and has also been used in telecommunications equipment.

Working Principle

The 3N246-E4/72 bridge rectifier works in the following way: the input voltage is applied across the two input terminals of the bridge. As the voltage alternates between positive and negative polarity, the diodes that are connected in series switch on and off in pairs, effectively rectifying the input voltage waveform. The rectified voltage is thereafter obtained at the output terminals and is then provided to the motor, the appliance, etc.

The 3N246-E4/72 bridge rectifier is designed to have low forward voltage drop so that it consumes less power. This helps to increase the efficiency of the bridge rectifier by as much as 10%. Additionally, the 3N246-E4/72 bridge rectifier features an enhanced temperature range, which helps it to withstand high temperatures in automotive applications. The ceramic fusing further protects the bridge rectifier from potential damage caused by voltage spikes or power surges.

The 3N246-E4/72 bridge rectifier is an efficient, cost-effective solution for automotive and power supply applications. Its versatile features make it suitable for a wide range of applications and its robust design helps prevent damage from voltage spikes or power surges.
