Rectifier Bridge KBP307 3A 700V

The Rectifier Bridge KBP307 3A 700V is a single-phase full-wave bridge rectifier that packs four diodes into one compact package with four in-line leads. It converts AC, for example from a transformer, into DC with an average output current of up to 3 A. The 700 V in the name is its maximum RMS input voltage, while the peak repetitive reverse voltage rating is 1000 V.

Rectifier Bridge KBP307 3A 700V Specifications

Rectifier Bridge KBP307 3A 700V Applications

• DC power supplies built with a mains transformer
• Battery chargers and LED drivers
• Polarity protection on DC inputs, so a device works with either wire order
• Repair of power boards, adapters and appliances
• Power electronics labs and student projects

What's in the Box

• 1 × KBP307 bridge rectifier

Tip: The + and − leads are marked on the body; the two ~ leads go to the AC source. Add a smoothing capacitor after the bridge: the DC output peaks at about 1.41 × the AC RMS voltage minus about 2 V for two diode drops, so 12 V AC gives about 15 V DC. Allow cooling when running near 3 A.
