Bridge Rectifier Diodes
🔥 25A 400V Bridge Rectifier Diodes – Heavy Duty Power Conversion for DC Projects
These KBPC2504 bridge rectifiers are workhorses in the world of high-current DC conversion. Rated for 25 Amps and up to 400 Volts, they’re perfect for applications where you need to take AC input and turn it into smooth, usable DC power.
⚙️ What it does:
This full-wave silicon rectifier takes your AC input and flips the negative half of the wave positive, giving you pulsating DC. Add a capacitor bank and you’re on your way to clean DC voltage, ready to power motors, drives, or control circuits.
🔧 My Use Case:
I use these specifically in builds where I retrofit treadmill motors (90V DC rated) with aftermarket servo driver boards. These boards are DC-in / DC-out, so I use the KBPC2504 to convert standard AC wall power (120V or 220V depending on the setup) to DC before feeding the driver. These things hold up under load and don’t blink when motors start drawing surge current.
📐 Tech Specs:
- Max Repetitive Reverse Voltage: 400V
- Average Forward Current: 25A
- Peak Forward Surge Current: 300A
- Mount Style: Chassis mount or bolt-through heat sink
- Compact square-body design with faston tabs for easy hookup
🧠 Why it matters:
If you’re running DC motor controllers, LED power systems, battery chargers, or any DC electronics from an AC line, you need a solid bridge rectifier. The KBPC2504 gives you the current handling you need without the bulk of a full SMPS or the fragility of underspec diodes.
