Overview
The BAW62,143 is a high-speed switching diode manufactured by NXP USA Inc. It utilizes planar technology and is encapsulated in a hermetically sealed leaded glass SOD27 (DO-35) package. The component features a maximum repetitive peak reverse voltage of 75 V and an average forward rectified current of 250 mA. It is designed for fast recovery applications with a specified speed class.
Feature Summary
- High-speed switching capability fabricated using planar technology
- Hermetically sealed leaded glass construction for environmental protection
- Axial leaded package design suitable for through-hole mounting
Applications
- General purpose high-speed switching circuits
- Voltage regulation applications
- Fast recovery rectification tasks
Procurement Notes
Verify the specific ordering code BAW62,143 to ensure compatibility with NXP specifications. Confirm that the ALF2 package variant matches your board layout requirements. Check for updated datasheets reflecting any recent company name changes from Nexperia to NXP Semiconductors to ensure accurate technical reference during integration.
Selection Notes
Select this component when a hermetically sealed axial diode with 75 V reverse voltage rating is required. The 250 mA current capacity suits moderate power switching needs. Ensure the DO-35 footprint aligns with existing PCB designs. Consider the planar technology benefits for consistent performance in high-speed environments compared to older junction types.
Part Context
This part belongs to the BAW series of high-speed diodes produced by NXP Semiconductors. The series includes various variants optimized for different voltage and current ratings within the same hermetically sealed glass package family. The BAW62 specifically targets applications requiring reliable fast recovery characteristics in a standard axial form factor.
Replacement Considerations
The 1N4148 is a common alternative for general-purpose switching, though it differs in package and specific electrical limits. Verify that substitute components meet or exceed the 75 V reverse voltage and 250 mA forward current requirements while maintaining comparable switching speeds.
