ZMD16

Single Zener Diodes Overview

The ZMD16 is a surface-mount non-planar Zener diode from Diotec Semiconductor, housed in the DO-213AA (MiniMELF) plastic package. It features a nominal Zener voltage range of 15.3 V to 17.1 V at a test current of 5 mA, with a standard tolerance aligned to the E24 series (~5%). The device supports a maximum power dissipation of 1 W and operates within a junction temperature range of -50°C to +175°C. Key electrical characteristics include a dynamic resistance of 13 Ohms at 1 kHz, a reverse leakage current of 1 µA at 500 mV, and a maximum Zener current of 58 mA at an ambient temperature of 50°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm that the required automotive grade matches the project specifications before finalizing orders. Standard commercial versions lack these specific automotive certifications.

Single Zener Diodes Selection Notes

Select this component for applications requiring stable reference voltages or regulation within the 15 V to 17 V range. Ensure the circuit design accommodates the 1 W power dissipation limit and the specified thermal resistance values. Verify that the required reliability level aligns with the standard commercial grade unless an AEC-Q101 qualified variant is explicitly needed.

Single Zener Diodes Part Context

This part belongs to the ZMD1...ZMD100 series of SMD Zener diodes utilizing non-planar technology. The series covers a broad voltage spectrum from 1 V to 100 V, all sharing the same MiniMELF package and 1 W power rating. This family is designed for general-purpose commercial and industrial electronic applications requiring reliable voltage clamping.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 1 W power rating, DO-213AA package, and similar Zener voltage tolerances. Cross-referencing should focus on components offering comparable dynamic resistance and thermal characteristics within the same voltage class.
