- Power supply rectification
- Inverter circuits
- General-purpose switching applications
Procurement Notes
Verify the specific datasheet revision and electrical parameter tolerances against the manufacturer's official documentation before integration. Confirm that the DO-201 through-hole package aligns with the target PCB footprint and assembly requirements. Ensure compliance with relevant RoHS and REACH directives as specified in the product data sheet.
Selection Notes
Select this component for designs requiring high-speed rectification with moderate current capacity. The DO-201 package facilitates easy manual or automated through-hole assembly. Consider the 400 V reverse voltage rating to ensure adequate margin for the circuit's peak inverse voltage conditions.
Part Context
This component belongs to Diotec Semiconductor's discrete diode portfolio, specifically categorized under fast recovery rectifiers. It serves as a standard solution for general-purpose power electronics where rapid switching and reliable conduction are required.
Replacement Considerations
Cross-reference with other 400 V, 3 A fast recovery diodes in the DO-201 package. Verify pinout compatibility and thermal resistance values when substituting with equivalent parts from other manufacturers.
