5 FAQs of Diode Bridge Rectifier KBJ408 Bridge Rectifier

The KBJ408 is a bridge rectifier diode. It changes AC voltage to DC voltage. People often ask these questions about it.

What does the KBJ408 bridge rectifier do? វាបំប្លែងចរន្តឆ្លាស់ (AC) ចូលទៅក្នុងចរន្តផ្ទាល់ (ឌី.ស៊ី). This is needed for many electronic devices running on DC power. It combines four diodes in one package.

What voltage can the KBJ408 handle? Its maximum input AC voltage is 400 វ៉ុល. Its maximum average forward current is 4 amps. These limits are important. Exceeding them damages the component.

How do I connect the KBJ408? It has four pins. Two pins are for the AC input voltage. You connect your AC source here. The other two pins give the positive and negative DC output. You connect these to your circuit. Check the pinout diagram carefully.

Does the KBJ408 need a heatsink? It depends on your current draw. Running near its 4A limit requires a heatsink. Using it without a heatsink at high currents causes overheating. Overheating leads to failure.

What happens if the KBJ408 fails? A failed rectifier often causes no DC output. Your device stops working. Sometimes you see excessive heat. Sometimes you smell burning. Check its input and output voltages. Replace it if faulty.
