Single Diodes Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to ensure correct packaging and compliance status. Confirm RoHS and material composition declarations via the manufacturer's Material Composition Declaration (MCD) resources prior to integration. Cross-reference datasheet revisions to validate electrical parameters and mechanical dimensions for your specific production batch.

Single Diodes Selection Notes

Select this component when a small surface-mount diode is required for high-voltage switching tasks. The SOD-123 package offers a balance between current handling capacity and footprint size. Ensure the application voltage does not exceed the 250 V rating and that the thermal environment supports the 200 mA continuous current limit without excessive junction temperature rise.

Single Diodes Part Context

This part belongs to onsemi's high voltage switching diode portfolio, often derived from established SOT-23 technologies adapted for surface mount formats. It serves as a robust solution for replacing through-hole components in modern PCB layouts where space optimization and high voltage isolation are critical design constraints.

Single Diodes Replacement Considerations

Check for compatible substitutes such as the BAS21AMR6T, which also offers high voltage switching capabilities. Verify pinout compatibility and electrical parameter overlaps before substitution to ensure circuit integrity and performance consistency in existing designs.
