ZMD11

Single Zener Diodes Overview

The ZMD11 is a surface-mount non-planar Zener diode manufactured by Diotec Semiconductor in the DO-213AA (Plastic MiniMELF) package. It features a power dissipation of 1 W and operates within a junction temperature range of -50°C to +175°C. The nominal Zener voltage is 11 V, with a tolerance band from 10.4 V to 11.6 V at a test current of 5 mA. Dynamic resistance is specified as 6 Ohms at 1 kHz, while maximum reverse leakage current is 1 µA at 75% of nominal voltage. Maximum Zener current is 86 mA.

Single Zener Diodes Procurement Notes

Verify the specific suffix when ordering. Suffix -Q indicates AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm that the component meets commercial or industrial grade requirements. Ensure the design accounts for standard E24 voltage tolerances unless otherwise requested. Check datasheet notes regarding production date codes and reverse voltage specifications.

Single Zener Diodes Selection Notes

Select this component for applications requiring high power dissipation in a compact Plastic MiniMELF form factor. Consider the thermal resistance values when designing PCB layouts. Verify if automotive-grade reliability is required to determine the appropriate suffix. Evaluate the dynamic resistance and leakage current against circuit sensitivity requirements.

Single Zener Diodes Part Context

This device belongs to the ZMD1 through ZMD100 series of SMD Zener diodes. The series utilizes non-planar technology and offers a wide range of Zener voltages from 1 V to 100 V. All variants share the same DO-213AA package and general mechanical characteristics, differing primarily in their specific voltage ratings and corresponding electrical parameters.

Single Zener Diodes FAQ

How is the cathode identified on the ZMD11?

The cathode is indicated by one blue ring on the component body.

What is the operating mode of the ZMD1?

The ZMD1 is operated in forward mode; therefore, all parameter indices use 'F' instead of 'Z', and the cathode must be connected to the negative pole.
