Product Description

Vishay KBU8K-E4/51 Bridge Rectifier is a single-phase, 4-pin component designed for through-hole mounting on printed circuit boards using the KBU package format.

This bridge rectifier converts alternating current (AC) into direct current (DC), providing full-wave rectification with the same output polarity regardless of AC input polarity. It is essential in power supply circuits, industrial equipment, and electronic devices requiring DC voltage derived from AC mains.

The device features a peak reverse repetitive voltage (Vrrm) of 800 V and can handle peak non-repetitive forward surge currents (Ifsm) up to 300 A, which makes it suitable for robust, high-load applications. The forward current rating (If) of 8 A supports continuous operation in medium power circuits.

Operating temperature ranges from -50°C to a maximum of 150°C, ensuring performance even in harsh environments. The compact dimensions of 23.7 mm length, 7.1 mm width, and 19.3 mm height allow space-efficient PCB layouts. The peak forward voltage drop of 1 V and low peak reverse current of 10 μA enable efficient power conversion with minimal losses.

Through-hole mounting for easy soldering and integration. High surge current capacity suitable for transient conditions. Compact and reliable for industrial electronic assemblies. Stable performance over a wide temperature range.

Ideal for power supplies, motor drives, and industrial automation equipment.

Vishay's KBU Series Bridge Rectifiers are well-known for their durability and performance in semiconductor power applications. This product supports engineers and designers in delivering efficient, compact, and reliable rectification solutions.
