Procurement Notes
Verify the specific part number suffix against official documentation to confirm compliance with RoHS directives and material categorization standards. Ensure that the ordering code matches the required delivery mode, such as ammo pack packaging, as specified in the manufacturer's ordering information. Cross-reference technical parameters with the latest datasheet revision to validate suitability for the intended operating conditions.
Selection Notes
Select this component based on its 1000 V reverse voltage rating and 1.0 A continuous current capacity. Consider the 175 °C maximum junction temperature for high-thermal environments. Evaluate the 25 A peak forward surge current capability for transient protection requirements. Confirm that the DO-41 through-hole package aligns with the printed circuit board layout constraints.
Part Context
This device is part of the 1N4942GP through 1N4948GP family of glass passivated junction fast switching plastic rectifiers. The GP designation indicates the use of the Superectifier structure. The E3 suffix denotes RoHS compliance and JESD 201 class 1A whisker test qualification. The /73 suffix specifies the ammo pack delivery mode with a base quantity of 3000 units.
Replacement Considerations
Other members of the 1N494xGP series may serve as substitutes if the reverse voltage rating meets or exceeds the application requirement. Verify that alternative components maintain equivalent thermal resistance and package dimensions for direct replacement.
