Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm RoHS compliance status, as the base part number includes both compliant and non-compliant variants. Confirm that the /TR suffix indicates tape and reel packaging rather than bulk supply. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for this JEDEC registered component.

Single Diodes Selection Notes

Select this component when a low-cost, high-speed switching diode with a 35 V reverse voltage rating is required. It is suitable for decoding or encoding applications where fast response is critical. Consider the DO-35 package constraints for board layout. Verify that the 200 mA average current rating meets the circuit requirements before finalizing the selection.
