Single Diodes Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant in available documentation. Confirm lead times directly with the manufacturer due to potential supply chain variability. Ensure the ordering suffix matches the required packaging configuration. Validate that the DO-205AA package dimensions align with the target PCB or chassis mounting constraints before finalizing procurement.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 150 A continuous current capacity are required. The stud mount configuration necessitates appropriate heatsinking infrastructure. Consider the 1.1 V forward voltage drop for thermal management calculations. Verify that the standard recovery speed meets the circuit switching requirements without generating excessive electromagnetic interference.
