ZMC9.1

Single Zener Diodes Overview

The Diotec Semiconductor ZMC9.1 is a surface-mount planar Zener diode housed in a MicroMelf (Quadro Glass Case) package. It features a nominal Zener voltage of 9.1 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -50°C to +175°C. Electrical characteristics include a dynamic resistance of less than 10 ohms at 1 kHz, a reverse leakage current of under 50 µA at the rated voltage, and a test current of 5 mA.

Single Zener Diodes Feature Summary

• Sharp Zener voltage breakdown for precise regulation
• Low leakage current performance
• Compliant with RoHS directives without exemptions

Single Zener Diodes Applications

• Voltage stabilization circuits
• Electronic regulators

Single Zener Diodes Procurement Notes

Verify the specific datasheet version and revision date before finalizing designs, as Diotec reserves the right to modify product information without notice. Confirm that the commercial/industrial grade reliability meets your application requirements, as this component is not AEC-Q101 qualified. Ensure compliance with REACH regulations and conflict mineral sourcing standards during the procurement process.

Single Zener Diodes Selection Notes

Select the ZMC9.1 when a compact SMD Zener solution is required for standard voltage reference applications. This component is suitable for designs needing a 9.1 V reference with a 500 mW power rating in a small glass case. Note that it is not automotive-grade; use the MM3Zxx-AQ series if AEC-Q101 qualification is mandatory for the target environment.

Single Zener Diodes Part Context

This component belongs to the ZMC2.4 through ZMC75 series of SMD Planar Zener Diodes produced by Diotec Semiconductor. The series utilizes a MicroMelf or Quadro Glass Case package, offering a standardized footprint for surface-mount assembly. These devices are designed for general-purpose voltage regulation tasks in commercial and industrial electronic equipment.

Single Zener Diodes Replacement Considerations

For automotive applications requiring AEC-Q101 qualification, the MM3Zxx-AQ series is the recommended alternative from Diotec. Verify pinout compatibility and thermal resistance specifications when substituting with other manufacturers' MicroMelf packages.
