MB4S

The MB4S is a bridge rectifier diode produced by ON Semiconductor, a leading semiconductor manufacturer. This diode is designed to rectify alternating current (AC) voltage into direct current (DC) voltage in electronic circuits, making it suitable for various applications where AC to DC conversion is required.

Key Features:

• Bridge Rectifier Configuration: The MB4S diode is configured as a bridge rectifier, consisting of four diodes arranged in a bridge configuration. This configuration allows for full-wave rectification of AC voltage, resulting in a smoother output voltage compared to half-wave rectification.

• Low Forward Voltage Drop: The diode features a low forward voltage drop, which is the voltage drop across the diode when it is conducting current in the forward direction. A low forward voltage drop reduces power losses and improves the efficiency of the rectification process.

• High Surge Current Capability: ON Semiconductor designs its bridge rectifier diodes with high surge current capability, allowing them to withstand short-duration overcurrent conditions without sustaining damage. This feature ensures reliability in applications where transient current spikes may occur.

• Fast Reverse Recovery Time: The MB4S diode has a fast reverse recovery time, which is the time taken for the diode to switch from the conducting to the non-conducting state when the voltage polarity across it changes. A fast reverse recovery time minimizes switching losses and improves the efficiency of the rectifier circuit.

• Surface-Mount Package: The diode is housed in a compact surface-mount SMB (DO-214AA) package, which is suitable for automated assembly processes and space-constrained PCB layouts. The surface-mount package facilitates easy integration into electronic designs without the need for through-hole mounting.

• Wide Operating Temperature Range: The MB4S diode is designed to operate reliably over a wide temperature range, typically from -55°C to 150°C, ensuring suitability for various environmental conditions and industrial applications.

• RoHS Compliance: The diode complies with the Restriction of Hazardous Substances (RoHS) directive, ensuring that it meets environmental standards for the elimination of hazardous materials in electronic components.

Applications:

• Power Supplies: Used in AC to DC power supply circuits, battery chargers, and voltage regulator modules to convert AC voltage from the mains power supply into DC voltage for electronic devices and equipment.

• Consumer Electronics: Integrated into consumer electronics products such as LED lighting fixtures, home appliances, and audio equipment for rectifying AC voltage from the mains power grid or external adapters.

• Industrial Automation: Deployed in industrial control systems, motor drives, and PLCs (Programmable Logic Controllers) for converting AC voltage to DC voltage in various automation and manufacturing processes.

• LED Drivers: Utilized in LED driver circuits for converting AC voltage to DC voltage to power LEDs in lighting applications such as LED bulbs, strips, and luminaires.

• Battery Chargers: Incorporated into battery charging circuits for rectifying AC voltage from the mains power supply to charge rechargeable batteries in mobile devices, power tools, and electric vehicles.
