• Hermetically sealed leaded glass package
• High switching speed capability
• Planar technology fabrication

Applications

• High-speed switching

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, as the base part number may correspond to different reel or tape configurations. Confirm that the component status remains active for new designs by consulting the most recent manufacturer documentation before initiating procurement processes.

Selection Notes

Select this component when a hermetically sealed axial leaded package is required for high-speed signal processing. Ensure the design accommodates the 100 V reverse voltage rating and the 500 mW thermal dissipation limits under expected operating ambient temperatures.

Part Context

This component belongs to the 1N4148/1N4448 series of high-speed diodes manufactured by Nexperia USA Inc. It shares the same physical package and general electrical characteristics as the 1N4148 but is distinguished by specific forward voltage parameters defined in the product data sheet.

Replacement Considerations

The 1N4148 serves as a direct functional substitute within the same series. Verify that any replacement maintains the required hermetic sealing and axial leaded package specifications.
