Single Zener Diodes Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Vishay General Semiconductor. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory. Engineers must confirm the specific ordering suffix matches the required tape-and-reel configuration. Replacement strategies should prioritize the recommended substitute part numbers provided by the manufacturer to ensure functional compatibility.

Single Zener Diodes Selection Notes

Designers selecting this component should note its specific 24 V Zener rating and 1.25 W power handling capability within the SMA footprint. The ±2% tolerance makes it suitable for precision applications requiring stable voltage references. Consideration of the AEC-Q101 qualification is essential for automotive projects. Due to the discontinued status, alternative sourcing channels or direct substitution with the recommended Vishay part number are necessary for new production runs.
