Overview
The B4S-G is a single-phase bridge rectifier manufactured by Comchip Technology, utilizing Silicon MBS (Miniature Bridge Structure) technology. It features a peak reverse voltage of 400 V and an average forward rectified current of 800 mA. The device exhibits a maximum forward voltage of 1.1 V at 800 mA and a leakage current of 5 µA at 400 V. Designed for surface mount installation, it operates within a junction temperature range of -55°C to +150°C. The component is housed in a TO-269AA package, also referred to as MBS, ensuring compact integration into electronic circuits.
Feature Summary
- Utilizes Miniature Bridge Structure (MBS) technology for compact footprint
- Supports surface mount installation via TO-269AA package
- Rated for high junction temperatures up to 150°C
Applications
- General purpose AC to DC conversion in power supplies
- Bridge rectification in compact electronic devices
- Surface mount circuit design requiring small form factor
Procurement Notes
Verify the specific ordering suffix and manufacturer part number against official Comchip Technology documentation before procurement. Confirm RoHS compliance status and environmental certifications required for the target application. Ensure the supplier provides valid traceability documents and datasheets matching the exact component revision to avoid discrepancies in electrical characteristics or packaging specifications.
Selection Notes
Select this component when a single-phase bridge rectifier with 400 V reverse voltage and 800 mA current capacity is required in a surface mount configuration. Consider the MBS package size constraints and thermal management capabilities relative to the expected operating environment. Verify that the 1.1 V forward voltage drop aligns with the efficiency requirements of the specific power supply design.
Part Context
The B4S-G belongs to the B4S series of bridge rectifiers from Comchip Technology. This series focuses on providing reliable rectification solutions in miniature packages suitable for modern surface mount assembly processes. The MBS technology allows for higher density PCB layouts compared to traditional through-hole bridge rectifiers while maintaining standard electrical performance ratings for general-purpose applications.
Replacement Considerations
Comchip Technology lists B4S-HF as a manufacturer-recommended alternative. Verify electrical compatibility and package dimensions before substitution.
