KBL403G

Overview

The KBL403G is a single-phase standard bridge rectifier manufactured by GeneSiC Semiconductor. It utilizes silicon technology and features a through-hole KBL package with four pins. The device supports an average forward rectified current of 4 A and offers a maximum repetitive peak reverse voltage of 300 V. Key electrical parameters include a forward voltage of 1.1 V at 4 A and a reverse leakage current of 5 µA at 300 V. It operates within a junction temperature range of -50°C to 150°C and has a maximum non-repetitive peak forward surge current of 120 A.

Feature Summary

• Glass passivated junctions for enhanced stability and reliability under varying conditions.
• High surge current capability designed to withstand transient overload events during operation.
• Compliant with international standards including IEC 60134-1 and UL recognition.

Applications

• AC-DC power supply circuits requiring reliable bridge rectification.
• Battery charging systems utilizing low-voltage AC inputs.
• General-purpose DC power supplies in consumer electronics.

Procurement Notes

Verify the manufacturer designation on official datasheets, as distributor listings may occasionally display conflicting brand names such as Navitas Semiconductor due to corporate acquisitions. Confirm the specific suffix 'G' indicates glass passivation and compliance with RoHS directives. Ensure the ordering information matches the KBL package style and pin configuration required for the target PCB layout.

Selection Notes

Select the KBL403G when a 300 V reverse voltage rating is necessary for the application's peak inverse voltage requirements. The 4 A current capacity suits moderate power loads compared to lower-rated variants like the KBL402G or higher-rated options like the KBL604G. Consider the thermal management capabilities inherent to the KBL through-hole package for heat dissipation needs.

Part Context

The KBL403G belongs to the KBL series of single-phase bridge rectifiers from GeneSiC Semiconductor. This series provides standardized solutions for general-purpose rectification tasks. The component shares physical dimensions with other KBL models but differs in voltage ratings, allowing designers to select appropriate breakdown voltages while maintaining consistent mounting footprints across different power stages.

Replacement Considerations

Compatible substitutes include the KBL403 from other manufacturers offering identical 4 A and 300 V specifications. Verify that alternative components maintain the same KBL package outline and pinout to ensure mechanical compatibility without PCB redesign.
