Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and tape specifications. Confirm RoHS compliance status and environmental declarations directly from the manufacturer datasheet prior to procurement. Ensure the selected variant matches the required voltage tolerance and thermal performance parameters for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 47 V reference is required in a compact surface-mount form factor. Consider the 3.0 W power handling capability relative to available board space and thermal resistance to the mounting plane. Verify that the DO-216AA footprint aligns with the PCB layout requirements and that the operating temperature range meets system specifications.

Single Zener Diodes Part Context

This part belongs to the Microsemi (now Microchip) Powermite series of low-noise Zener diodes. The series spans voltages from 3.3 V to 200 V in the DO-216AA package. These devices serve as surface-mount equivalents to larger through-hole packages while offering superior thermal dissipation through their unique tab design.

Single Zener Diodes Replacement Considerations

Compatible replacements within the same series include 1PMT5940B and 1PMT5942B for adjacent voltage ratings. Cross-manufacturer equivalents may exist but require verification of pinout, thermal resistance, and electrical tolerances against the original datasheet specifications.
