KBPF306G

Overview

The KBPF306G is a high-voltage, fast-recovery planar passivated silicon bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak reverse voltage of 600V and an average forward rectified current rating of 3A at 75°C. The device utilizes a glass-passivated junction for enhanced stability and includes a molded epoxy body compliant with UL flammability standards (UL94 V-0). Key electrical characteristics include a maximum RMS blocking voltage of 420V, a surge forward current capacity of 100A, and a low forward voltage drop of 1.1V at rated current. Reverse leakage current is specified at a maximum of 5µA at 600V.
