Procurement Notes

Verify the package type against project requirements, as distributor listings may indicate surface mount variants while official datasheets specify through-hole configurations. Confirm RoHS compliance status directly with the manufacturer, as regulatory markings can vary by production batch. Ensure the ordering suffix matches the required lead time and packaging format. Cross-reference the specific revision level of the datasheet to confirm electrical parameters align with design constraints before finalizing procurement.

Selection Notes

Select this component when a fast recovery rectifier with a 100 V rating and 2.5 A continuous current capacity is required. The low reverse leakage current makes it suitable for sensitive circuitry. Consider the thermal management capabilities given the wide operating temperature range. Evaluate the package style compatibility with the printed circuit board layout, ensuring the chosen variant matches the assembly method specified in the design documentation.

Part Context

The 1N5804 belongs to the family of fast recovery rectifiers manufactured by Microchip Technology.
