Single Zener Diodes Procurement Notes

Verify the specific suffix M3-08 to confirm lead-free compliance and tape-and-reel packaging configuration. Ensure the DO-214AC footprint matches the design layout. Confirm availability status as manufacturing statuses may change without notice.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V Zener voltage is required in a SMA package. Consider the 1.25 W power rating for thermal management. Verify that the ±2.09% tolerance meets circuit requirements. Check if the 13 Ω impedance is suitable for the application's dynamic load conditions.

Single Zener Diodes Part Context

This part belongs to the BZG05 series of high-power Zener diodes from Vishay. The series offers various voltage options within the DO-214AC package. The M3 suffix indicates RoHS compliance and halogen-free construction. The -08 suffix typically denotes tape-and-reel packaging for automated assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 3.9 V Zener voltage, 1.25 W power rating, and DO-214AC package. Verify pinout compatibility and electrical characteristics such as impedance and leakage current before substitution.
