KBPF407G

Overview

The KBPF407G is a bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a single-phase full-wave configuration with four elements integrated into one package. The device provides a peak repetitive reverse voltage of 400 V and a maximum average forward rectified current of 1 A at 75 °C. It utilizes a DO-201AD (DO-15) axial leaded plastic encapsulation. Key electrical parameters include a non-repetitive peak forward surge current of 30 A and a maximum RMS isolation voltage of 2500 Vrms. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Single-phase full-wave bridge rectification
• High thermal stability for demanding environments
• Robust mechanical construction for through-hole mounting

Applications

• General-purpose power supply circuits
• Battery charging systems
• DC power adapters

Procurement Notes

Verify the manufacturer part number against official Taiwan Semiconductor documentation to ensure authenticity. Confirm that the DO-201AD package dimensions match your PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to your specific manufacturing process or end-use application.

Selection Notes

Select this component when a compact, single-phase bridge rectifier is required for low-to-medium current applications. Ensure the circuit's peak inverse voltage does not exceed the 400 V rating. Verify that the expected forward current remains below the 1 A limit under worst-case thermal conditions to maintain reliability and prevent overheating.

Part Context

This component belongs to the family of general-purpose silicon bridge rectifiers designed for AC-to-DC conversion. It serves as a fundamental building block in electronic power supplies, offering a reliable solution for converting alternating current into direct current in consumer electronics and industrial control equipment.

Replacement Considerations

Consult official cross-reference lists from Taiwan Semiconductor for verified equivalents. Ensure any substitute matches the 400 V reverse voltage, 1 A current rating, and DO-201AD package form factor.
