When purchasing the DF60BA80 power diode module, consider the following factors to ensure compatibility and optimal performance for your application:
• Voltage & Current Rating - Handles 800V and 60A make sure it matches your system’s needs.
• Heat Management - Generates heat, so check if a heatsink is needed. Works best within safe temperature limits don’t overload it.
• Installation & Size - Check if it fits your setup (PCB or panel mounting). Some models use screw terminals for easy installation.
• Speed & Performance - Works well in rectifiers, inverters, and motor drives. If used in high-frequency circuits, check how fast it switches.
• Protection & Durability - Has a built-in diode to help prevent damage. Might need extra protection against short circuits.
• Buying from the Right Source - Avoid fake parts buy from trusted sellers such as IC-Components. Check pricing and availability before ordering.
The circuit diagram shown represents the internal structure of the DF60BA80 three-phase bridge rectifier module. This module is designed to convert an AC input into a DC output using six internally connected diodes arranged in a three-phase rectifier configuration.
At the top, terminals 1~, 2~, and 3~ serve as the three-phase AC input connections. Each of these inputs is connected to a pair of diodes in a bridge arrangement. The diodes are oriented to allow current to flow in only one direction, ensuring rectification of the AC waveform. The cathodes of the upper diodes and the anodes of the lower diodes are connected to the DC output terminals.
The +4 terminal represents the positive DC output, where the rectified voltage is collected, while the −5 terminal serves as the negative or ground connection. This configuration ensures that the module efficiently converts three-phase AC into a stable DC supply, making it suitable for industrial motor drives, power supplies, and other high-power rectification applications.

The DF60BA80 mechanical dimensions and mounting details provide information for proper installation and integration into electrical systems. The module has an overall width of 80 mm and a height of 35 mm, with a base width of 60 mm, ensuring a compact yet robust design for industrial applications.
The top view shows the layout of the terminal connections, spaced 21.5 mm apart, with a central spacing of 10 mm between specific terminals. The module includes five M5 screw terminals, which provide secure electrical connections for both AC input and DC output. The mounting holes are positioned 67 mm apart, with 1.1 mm offsets for alignment.
The side profile reveals a mounting base of 3.2 mm thickness, ensuring stability when secured to a heatsink or panel. With a height of 25 mm from the base to the top terminals, the module maintains a low-profile design, aiding in heat dissipation and mechanical durability. These dimensions are great for ensuring proper fitment in power electronics assemblies, specially in rectifier circuits and motor drives.

• Connect the AC Power
- Find the AC input (from mains or a transformer).
- Connect one wire to AC1 and the other to AC2.
• Connect the DC Output
- Find your DC-powered device (motor, LED, battery charger, etc.).
- Connect the + terminal to the positive side of your device.
- Connect the - terminal to the negative side of your device.
• Prevent Overheating
- Attach a heatsink to the rectifier to avoid overheating.
- Use thermal paste for better cooling.
• Add Extra Protection (Optional but Recommended)
- Fuse → Protects from too much current.
- Capacitor → Reduces voltage fluctuations.
- Surge Protector → Prevents voltage spikes.
• Power On and Test
- Double-check your connections.
- Turn on the AC power.
- Use a multimeter to check the DC output voltage.
