Bridge Rectifier Diode KBPC3510 (35A, 1000V)

Description

The KBPC3510 Bridge Rectifier Diode is a heavy-duty, single-phase electrical component designed to convert alternating current (AC) into direct current (DC). Engineered for high-power applications, this rugged rectifier can safely handle a maximum forward continuous current of 35 Amps and a peak reverse voltage of up to 1000 Volts (1kV).

Encased in a durable, electrically isolated metal housing, the KBPC3510 features a central mounting hole. This design allows it to be easily bolted directly to a heatsink or metal chassis to ensure optimal thermal dissipation during high-load operations. It utilizes standard 1/4" (6.35mm) fast-on spade terminals for quick and secure wiring. It is an essential component for building robust power supplies, heavy-duty battery chargers, and industrial motor control circuits.

Frequently Asked Questions (FAQ)

Q: Do I need to use a heatsink with this rectifier?
A: Yes. If you are drawing continuous currents above a few amps, the internal diodes will generate significant heat. It is highly recommended to bolt this rectifier to an appropriately sized aluminum heatsink using thermal paste to prevent thermal runaway and component failure.

Q: How do I wire the four terminals?
A: The top of the metal casing is marked with symbols. The two terminals marked with a tilde (~) or "AC" are where you connect your alternating current input. The terminal marked with a plus (+) is your positive DC output, and the unmarked terminal diagonally opposite to the positive pin is your negative (-) DC output.
