The MBR30200CT is a Schottky barrier rectifier diode module, designed for high-efficiency power rectification in power supply circuits. It features two diodes in a common cathode configuration, making it suitable for applications like power supplies, battery chargers, and other high-current DC circuits.

Key Specifications

Features

• Low Forward Voltage Drop: Reduces power losses and improves efficiency.
• High Current Capability: Suitable for high-current applications up to 30A.
• Fast Switching: Ideal for high-frequency circuits.
• Common Cathode Configuration: Two diodes share the cathode, simplifying circuit design.
• Thermal Efficiency: Compatible with heatsinks for improved thermal performance.

Applications

• DC-DC Converters: Used in output stages for rectification.
• Power Supplies: Provides efficient AC-to-DC conversion.
• Battery Chargers: Ensures low power loss and high efficiency.
• Solar Inverters: Utilized for rectification in renewable energy systems.
• Motor Control: Works as freewheeling diodes in motor drivers.

Pin Configuration (TO-220AB)

1. Anode 1 (A1): Connected to the first diode's anode.
2. Anode 2 (A2): Connected to the second diode's anode.
3. Cathode (K): Common cathode for both diodes.

Circuit Example

To use the MBR30200CT in a power supply rectification circuit:

1. Connect the AC voltage source to the anodes (A1 and A2) through a transformer (if necessary).
2. Connect the common cathode (K) to the positive DC output.
3. The negative DC output connects to the transformer's center-tap or AC source ground.

Design Considerations

1. Heat Management:
   • Use an appropriate heatsink with the TO-220 package to dissipate heat effectively.
2. Voltage Ratings:
   • Ensure the reverse voltage does not exceed 200V to avoid breakdown.
3. Current Ratings:
   • Keep the average rectified current below 30A (15A per diode) for safe operation.
4. Capacitor Smoothing:
   • Add a capacitor across the DC output for smoothing the rectified signal.
