KBPF305G B0G

Overview

The KBPF305G B0G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a glass-passivated junction within a KBFP package, designed for surface-mount applications on printed circuit boards. The device supports a repetitive peak reverse voltage of 600 V and an average forward rectified current of 3 A. Key electrical characteristics include a maximum forward voltage of 1.1 V at 1.5 A and a surge peak forward current capability of 80 A. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Utilizes glass passivation for the chip junction to ensure reliability and low leakage current.
• Constructed with molded plastic technique for reliable, low-cost assembly suitable for automated placement.
• Features matte tin-plated leads that are solderable per J-STD-002 standards.

Applications

• General purpose AC/DC bridge full wave rectification
• Switching Mode Power Supplies (SMPS)
• Space constrained appliance applications

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to confirm packaging details. The datasheet indicates standard packing in tubes of 35 units. Confirm compliance requirements such as RoHS and halogen-free status based on the suffix definitions provided in the mechanical data section before finalizing procurement specifications.

Selection Notes

Select this component when a 600 V blocking voltage and 3 A continuous current rating are required for PCB-mounted bridge rectification. Consider the thermal resistance values for heat dissipation planning in enclosed spaces. Ensure the application does not involve medical or life-sustaining systems, as these devices are explicitly excluded from such usage scenarios.

Part Context

This part belongs to the KBPF304G through KBPF307G series from Taiwan Semiconductor. The series shares identical physical dimensions and electrical performance limits regarding current and thermal handling, differing primarily in their maximum repetitive peak reverse voltage ratings. The KBFP package provides a compact footprint ideal for modern electronics manufacturing.

Replacement Considerations

Direct substitutes within the same series include KBPF304G, KBPF306G, and KBPF307G. Selection depends strictly on matching the required reverse voltage rating to the circuit design. Other manufacturers producing KBFP-style bridge rectifiers may serve as alternatives if pin compatibility and thermal characteristics align.
