Applications

• High-speed rectification circuits
• Power Schottky applications requiring fast recovery
• Electronic circuit components in surface mount assemblies

Procurement Notes

Verify the specific suffix (e.g., AS vs UTK3) against official Microchip documentation to ensure correct package and tape/reel specifications. Confirm RoHS compliance status directly from the manufacturer datasheet as availability varies. Cross-reference the part number with authorized distributors to validate current production status and lead times before procurement planning.

Selection Notes

Select this component when a surface-mount Schottky rectifier with fast recovery characteristics is required. Ensure the application voltage and current ratings align with the 1N6942 series specifications. Consider the epitaxial structure and guard ring protection if reverse energy handling is critical for the circuit design.

Part Context

This part is part of the broader 1N6940–1N6942 series managed by Microchip Technology. It falls under the category of Schottky Diodes & Rectifiers.
