Introduction
The KBPC5010 is a single-phase full bridge rectifier with a high surge current capability and an electrically isolated metal case for efficient heat dissipation. It is designed to convert AC voltage into DC voltage.
To rectify both half-cycles of a sine wave, the KBPC5010 full bridge rectifier uses four diodes, connected together in a “bridge” configuration. The secondary winding of the transformer is connected on one side of the diode bridge network and the load on the other side. The image below shows the bridge rectifier circuit, and the resulting input and output voltage waveforms. To smooth the resulting pulsating DC current use a filter, most often a high-capacity capacitor, connected to the output.

Pinout and Mechanical Specifications
Mounting
- Safety First: Ensure the power is off before beginning installation.
- Thermal Compound: Apply a thin, even layer of silicone thermal compound between the metal case of the rectifier and the mounting surface. This is crucial for efficient heat transfer.
- Mounting: Bolt the rectifier to the mounting surface using a screw through the center hole.
- Torque: Tighten the mounting screw to a maximum torque of 20 in-lb. Over-tightening can damage the device.
Wiring
The KBPC5010 has four terminals: two for AC input and two for DC output. The terminals are typically marked with symbols:
- ~ (AC): Connect the AC input voltage to these terminals.
- + (DC): Connect the positive DC output to this terminal.
- – (DC): Connect the negative DC output (ground) to this terminal.
Important: Verify the polarity of the DC output before connecting to your load. Incorrect polarity can damage the load.
Operating Conditions
Current: Do not exceed the maximum average forward rectified output current
Temperature: Ensure the operating temperature remains within the specified range of -55°C to +150°C.
