• High-reliability electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm compliance requirements. Ensure the selected variant matches the required screening level, such as JAN, JANTX, or JANTXV, if applicable. Confirm RoHS status by checking for the 'e3' suffix in the part number. Validate that the package outline corresponds to the DO-213AB MELF specification before procurement.

Single Zener Diodes Selection Notes

Select this component when a surface mount solution is required for voltages up to 200 V with a 1.5 W power rating. Consider the DO-213AB package dimensions for PCB layout compatibility. Evaluate the thermal resistance of 120°C/W junction-to-ambient on FR4 for heat dissipation planning. Verify that the 180 V breakdown voltage aligns with the circuit's regulation needs.

Single Zener Diodes Part Context

This device belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface mountable Zener diodes. The series serves as a surface mount equivalent to the JEDEC registered 1N3016 through 1N3051 axial lead devices, offering higher power ratings in a compact form factor. The product line supports various screening options via prefix modifications for military specifications.

Single Zener Diodes Replacement Considerations

Equivalent axial lead parts are available as 1N3050B. Surface mount equivalents include MLL3050B. Screening prefixes MQ, MX, MV, or MSP may be used to obtain JAN, JANTX, JANTXV, or JANS variants respectively.
