• High-density circuit board mounting
• Voltage regulation over broad operating currents and temperatures

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm screening levels and compliance options. The base part number indicates standard commercial availability, while prefixes such as MQ, MX, or MV denote equivalent screening to JAN, JANTX, or JANTXV standards per MIL-PRF-19500/115. Ensure the RoHS compliant 'e3' suffix is included if lead-free terminals are required for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a robust surface mount Zener diode is needed for voltage regulation in harsh environments. The DO-213AB package offers a higher power rating compared to traditional axial equivalents. Consider the metallurgically enhanced contacts for improved thermal performance and the inherent radiation hardness for specialized aerospace or defense applications where long-term stability is critical.

Single Zener Diodes Part Context

This device belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface mountable Zener diodes. It serves as the surface mount equivalent to the JEDEC registered 1N3016B through 1N3051B axial lead devices, adapted for the DO-213AB outline. The series provides a wide selection of voltages from 6.8 to 200 volts, maintaining the reliability characteristics of the original axial family in a compact form factor.

Single Zener Diodes Replacement Considerations

Equivalent axial lead versions include the 1N3047B. Surface mount alternatives within the same series include MLL3047B.
