Single Diodes Procurement Notes

Verify the specific ordering suffix '-F' confirms lead-free and RoHS compliance as documented in the manufacturer's datasheet. Confirm the package type matches SOD-123 requirements for your PCB layout. Ensure the component meets UL flammability classification rating 94V-0 standards if required by your design specifications. Cross-reference the date code and type code markings against official documentation to verify authenticity.

Single Diodes Selection Notes

Select this component when a low forward voltage drop and fast switching speed are required in a compact surface mount form factor. The 30 V reverse voltage rating suits low-voltage DC blocking and rectification tasks. Consider the 200 mA continuous current limit and 200 mW power dissipation capabilities during thermal analysis. Verify compatibility with automated assembly processes due to the SOD-123 package design.
