Single Diodes Procurement Notes

Verify the specific manufacturer datasheet for the 1N4148-G variant to confirm electrical tolerances and thermal characteristics. Ensure the DO-35 package dimensions match the target PCB layout requirements. Confirm RoHS compliance status directly with the supplier documentation before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with a 100 V reverse voltage rating is required. The 150 mA forward current limit suits low-power signal processing tasks. The wide operating temperature range up to 200°C allows use in demanding thermal conditions where standard 175°C rated parts may fail.

Single Diodes Part Context

This part belongs to the widely used 1N4148 family of small signal switching diodes. It serves as a general-purpose replacement for legacy designs requiring fast recovery characteristics. The DO-35 axial leaded package facilitates easy integration into through-hole manufacturing processes.

Single Diodes Replacement Considerations

Standard equivalents include the 1N4448 and generic 1N4148 variants. Verify that substitute components meet the same 100 V reverse voltage and 150 mA forward current specifications to ensure circuit compatibility.
