Procurement Notes
Verify the specific ordering suffix 'TR' to confirm tape and reel packaging configuration, as standard bulk variants exist. Confirm RoHS compliance status through official documentation prior to integration. Ensure the manufacturer part number matches exactly to avoid confusion with similar series components. Check for any recent product change notices regarding manufacturing location or material composition updates.
Selection Notes
Select this component when a small signal diode requires high forward current capability combined with low reverse leakage. The wide operating temperature range makes it suitable for demanding environments. Verify that the 200 V reverse voltage rating exceeds the circuit's peak inverse voltage requirements. Consider the DO-35 package constraints for PCB layout and mounting style compatibility.
