Overview
The KBL404-G is a silicon bridge rectifier diode manufactured by Comchip Technology. It features a 4 A average forward current rating and a maximum repetitive peak reverse voltage of 400 V. The device utilizes a glass passivated chip junction for enhanced reliability. It operates within a temperature range of -55 °C to +150 °C. The component is housed in a plastic KBL SIP-4 package, designed for surface mount applications with high surge current capability.
Feature Summary
- Glass passivated chip junction ensures high reliability and stable performance under varying conditions.
- Low profile package design offers improved thermal resistance and reduced board space requirements compared to standard packages.
- High surge current capability provides robust protection against transient voltage events.
Applications
- General purpose power supply rectification
- DC-DC converter input stages
- Battery charging circuits
Procurement Notes
Verify the specific manufacturer datasheet for the KBL404-G to confirm RoHS compliance status and exact pinout configuration. Ensure the supplier provides traceable documentation matching the Comchip Technology part number. Cross-reference the package dimensions with the official mechanical drawing to guarantee compatibility with existing PCB footprints.
Selection Notes
Select this component when a 4 A current rating and 400 V reverse voltage are required in a low-profile surface mount format. Consider the operating temperature range and thermal management needs for the specific application environment. Compare surge current ratings against potential load transients to ensure adequate safety margins during operation.
Part Context
This component belongs to Comchip Technology's Low Profile Rectifier series, which includes general purpose, fast recovery, and ultra-fast recovery variants. These devices share common design features such as glass passivation and high surge capability, differentiated primarily by their switching speed and voltage ratings within the same compact package family.
Replacement Considerations
Direct substitutes include other 4 A, 400 V bridge rectifiers in the KBL package, such as the KBL406 or KBL408 from various manufacturers. Verify that replacement parts maintain identical pin configurations and thermal characteristics to ensure seamless integration without PCB redesign.
