KBJ401G Discrete Semiconductor Products

KBJ401G is a type of diode bridge rectifier which is used in numerous commercial and industrial applications. It is one of the most common rectifier types and is used in most applications requiring DC power from an AC source. It is cost effective, has low power dissipation, and provides reliable operation with little or no maintenance.

A bridge rectifier is a type of rectifier that is used to convert alternating current (AC) to direct current (DC). It is composed of four diodes arranged in a bridge configuration that produces an output which is a DC voltage equal to or greater than the AC input. The KBJ401G is a specific type of bridge rectifier with a full-wave rectification, meaning that it will rectify both the positive and negative cycles of the AC input resulting in an output which is always positive.

The KBJ401G is a four-terminal bridge rectifier which consists of four copper heat sinking fin structures, two anode terminals, one cathode terminal, and one electric connection terminal. These copper heat sinking fin structures ensure that the device can dissipate the heat generated during operation and remain within the normal operating temperature range. Additionally, the placement of the terminals allows for a low profile and linear thermal dissipation.

The KBJ401G has a maximum junction temperature of 150°C and a frequency of 50/60Hz. It can handle peak currents of up to 400 Amps and voltage of up to 400V. It does not require the use of a snubber network and is designed to reduce common-mode noise, surge currents, and electromagnetic interference (EMI).

The working principle of the KBJ401G is based on the process of rectification. Rectification is a process of converting alternating current (AC) to direct current (DC). In a bridge rectifier, four diodes are arranged like a bridge where the alternating current (AC) is then passed through the circuit and rectified. The operation of the KBJ401G bridge rectifier is to pass current through 4 diodes, arranged in a bridge configuration and the alternating current is then converted to direct current.

The output voltage of the KBJ401G is not the same as the input voltage. The output voltage is dependent on the type of diode Bridge rectifier used, and is usually lower than the input voltage. This is due to the forward voltage of the diodes which is around 0.7 volts, meaning that for each diode the voltage will drop by 0.7 volts, resulting in a total drop of 2.8 volts. In addition to this, the bridge rectifier will also experience voltage losses due to the internal resistance and capacitance of the rectifier.

The KBJ401G has a wide range of applications. It is used in power supplies, dedicated power supplies, and battery chargers. It can also be used in DC motor controls, AC motor control circuits, and even in lighting applications. It is also used in the automotive industry for applications such as junction boxes and ECM control relays.

In conclusion, the KBJ401G bridge rectifier is a cost effective and reliable solution for many commercial and industrial applications. It offers high current handling capability, low power dissipation, and a wide range of applications. With its low profile and linear thermal dissipation, the KBJ401G is an effective solution for many applications.
