Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging configuration. The datasheet indicates availability in tape and reel or ammopack formats. Ensure that the procurement specifications align with the required mechanical dimensions and thermal resistance parameters defined in the manufacturer's technical data sheet.
Selection Notes
Select this component when a high-voltage small signal diode with fast switching capabilities is required. The DO-35 package provides through-hole mounting compatibility. Consider the 175 °C maximum junction temperature rating for thermal management. Verify that the 150 V reverse voltage rating meets the circuit requirements.
Part Context
This component belongs to the Vishay BAY series of small signal switching diodes. The series includes variants designed for general-purpose applications with varying voltage and current ratings. The BAY80 specifically targets applications requiring robust performance under high reverse voltage conditions while maintaining low capacitance for signal integrity.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the DO-35 package, 150 V reverse voltage rating, and 50 ns reverse recovery time specifications.
