1N4007 AC to DC Power Conversion Module

1N4007 AC to DC Power Conversion Module provides a robust, pre-built solution for rectifying standard AC power into pulsating DC voltage, forming the foundation of any non-regulated power supply. This module specifically utilizes the universally popular 1N4007 silicon rectifier diode, delivering a high maximum repetitive peak reverse voltage rating. Therefore, engineers typically select this device for applications connected directly to the 220V/120V AC mains supply after a step-down transformer. It effectively manages the current flow, blocking reverse voltage spikes up to 1000V. Consequently, this essential component simplifies prototyping and deployment in various consumer electronics and industrial control systems where reliability and cost-effectiveness are crucial design factors.

Key Features:

• High Voltage Handling: The core 1N4007 diode offers a high Maximum Recurrent Peak Reverse Voltage (V_RRM) of 1000V, ensuring safe operation on standard AC lines.
• Modular Design: The pre-assembled module simplifies integration into existing circuits, eliminating the need for manual diode wiring and soldering.
• Forward Current Capacity: It consistently handles an average rectified forward current (I_F(AV)) of 1.0 A, making it suitable for low to medium-power supplies.
• Low Forward Voltage Drop: The diode exhibits a low typical forward voltage drop, hence minimizing power loss and heat generation during operation.
• Universal Application: You can apply this module universally in half-wave or full-wave rectifier configurations (with an external center-tap transformer or bridge configuration).

Pinout and Wiring:

• Input (AC/Transformer): Connect the module’s input pins (or the diode’s anode in half-wave) to the AC source or transformer secondary winding.
• Output (+DC): This terminal supplies the pulsating positive DC voltage to the load or smoothing capacitor.
• Ground/Return (GND/DC-): Connect this pin to the circuit ground or the negative return line.
• Wiring Note: Always pair the rectifier module with a smoothing capacitor to convert the pulsating DC into stable DC voltage for sensitive loads. In addition, you must use a fuse for line-side protection.
