Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the packing method, as bulk, ammo pack, and tape-and-reel variants exist within the same part family. Ensure the selected packaging aligns with automated assembly requirements or manual handling needs. Confirm RoHS compliance status through official datasheets before procurement.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with high speed and low capacitance is required. The DO-35 package suits through-hole designs where space allows. Compare the 100 V reverse voltage limit against circuit peak voltages to ensure adequate margin. Consider the 4 ns recovery time for frequencies exceeding typical general-purpose diode capabilities.

Single Diodes Part Context

This component belongs to the 1N91x and 1N4x48 series manufactured by onsemi. It shares electrical characteristics with the 1N914 but offers optimized switching parameters. The series includes various packaging options such as SOD-80 surface mount devices, providing flexibility for different board layout constraints while maintaining consistent core performance metrics.

Single Diodes Replacement Considerations

The 1N914 serves as a direct functional equivalent within the same product family. Surface-mount alternatives include the FDLL4148 in the SOD-80 package. Verify pinout compatibility and package dimensions when substituting between axial lead and surface mount technologies.
