ON Semiconductor KBU4D Bridge Rectifier

The KBU4D is a single-phase silicon bridge rectifier from ON Semiconductor, renowned for its high efficiency and reliability in converting alternating current (AC) to direct current (DC). This component is designed to suit a wide array of applications, ranging from power supply units to lighting systems, and is particularly well-suited for use in consumer and industrial environments.

Key Features:

• High Current Capability: The KBU4D can handle a high forward current of up to 4A, making it suitable for circuits with higher current demands.
• Peak Repetitive Reverse Voltage: It is capable of withstanding peak repetitive reverse voltages (VRRM) up to 200V, ensuring stability and protection against voltage spikes.
• Low Reverse Leakage Current: Exhibits low reverse leakage current, which enhances its efficiency and reduces power loss.
• High Surge Current Capability: The device can manage a surge overload rating of 150A, providing robustness against short-term overcurrent conditions.
• Isolation Voltage: With an isolation voltage of 1500V from case to leads, it offers additional safety for the user and protection for the device.

Package and Mounting:

The KBU4D comes in a KBU package, which is a standard size for bridge rectifiers. Its through-hole mounting design allows for easy installation onto printed circuit boards (PCBs). The package is designed for optimal heat dissipation, ensuring the bridge rectifier operates within its intended temperature range even under full-load conditions.

Applications:

• Switching power supplies
• Adapters
• Motor controllers
• Audio equipment
• Other electronic devices requiring rectification

The KBU4D is a testament to ON Semiconductor's commitment to providing components that blend performance with practicality, offering designers a reliable and cost-effective solution for their rectification needs.
