Single Diodes Procurement Notes

Verify the specific ordering code matches the required packaging option, either tape and reel or ammo pack. Confirm that the component meets material categorization compliance standards defined by the manufacturer. Ensure the design accounts for the thermal resistance junction to ambient air value when calculating power dissipation limits under specified operating conditions.

Single Diodes Selection Notes

Select this component for designs requiring a small signal Schottky diode with low forward voltage drop and fast response times. The DO-35 package suits through-hole assembly processes. Consider the 30 V reverse voltage limit and 200 mA current rating to ensure adequate margins for the intended application environment and load requirements.

Single Diodes Part Context
