Bridge Rectifier 50V 3A (DOD803)

A bridge rectifier is an electronic component used to convert AC (alternating current) into DC (direct current). It contains four diodes arranged in a bridge configuration to provide full-wave rectification.

 Key Specifications

• Maximum Reverse Voltage: 50V
• Maximum Forward Current: 3A
• Type: Full bridge rectifier
• Terminals: 4 (AC ~, AC ~, +, −)
• Mounting: Through-hole (common types like W04, KBP, or similar)

 How it works

It converts both halves of the AC waveform into DC output:

VDC≈2VpeakπV_{DC} approx frac{2V_{peak}}{pi}VDC​≈π2Vpeak​​

👉 This results in a smoother DC output compared to half-wave rectifiers.

 Common Applications

• Power supply circuits
• Battery chargers
• LED drivers
• DIY electronics projects
• Converting transformer output (e.g., 12VAC → DC)

Typical connection

• ~ ~ (AC inputs): Connect to transformer output
• + (positive): DC output positive
• − (negative): DC output ground

👉 Often used with:

• Transformer (e.g., 12–24VAC)
• Smoothing capacitor
• Voltage regulator

 Important Tips

• Choose voltage rating higher than your AC input peak
• Add a heatsink if running near 3A
• Use a filter capacitor to smooth DC output
