Single Zener Diodes Procurement Notes

Verify that the ordering suffix M3 confirms halogen-free compliance and industrial grade status as specified in the datasheet. Confirm AEC-Q101 qualification requirements if deploying in automotive environments. Ensure the DO-215AA (SMBG) package dimensions align with the target PCB footprint layout before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when an 18 V regulation point is required in a compact surface-mount form factor. The SMBG package supports up to 1500 mW power dissipation. Verify that the 12 Ω maximum dynamic impedance meets the circuit's ripple rejection requirements. Consider the -55 °C to +150 °C operating range for harsh environmental conditions.

Single Zener Diodes Part Context
