Single Diodes Procurement Notes
Verify the manufacturer part number against official Microchip Technology documentation to ensure authenticity. Confirm that the DO-21 package type and press-fit termination match your board design requirements. Check for specific datasheet revisions or ordering suffixes that may affect electrical parameters or packaging details before finalizing procurement decisions.
Single Diodes Selection Notes
Select this component when a high-current rectifier with moderate reverse voltage blocking is required. Ensure the thermal management system can handle the power dissipation associated with a 35 A forward current. Verify that the press-fit mounting style is compatible with the target PCB layout and assembly process compared to through-hole alternatives.
Single Diodes Part Context
This component belongs to the 1N34 series of rectifiers, which are widely used in various semiconductor applications. Microchip Technology produces this specific variant, distinguishing it from similar parts made by other manufacturers like Motorola.
