ZMC47

Single Zener Diodes Overview

The ZMC47 is a surface-mount planar Zener diode manufactured by Diotec Semiconductor in the MicroMelf (DO-213AC) package. It provides a nominal Zener voltage of 47 V with a tolerance range of 44 V to 50 V at a test current of 5 mA. The device features a maximum power dissipation of 500 mW and operates within a junction temperature range of -50°C to +175°C. Key electrical characteristics include a dynamic resistance of less than 110 Ohms, a reverse leakage current of 100 nA at 36 V, and a thermal resistance from junction to ambient of less than 300 K/W.

Single Zener Diodes Procurement Notes

Verify that the specific order matches the ZMC47 part number and the standard E24 ±5% tolerance grade. Confirm compliance requirements such as RoHS and REACH status directly with the manufacturer or authorized distributor. Ensure the procurement documentation references the correct datasheet version to validate the specified electrical parameters and mechanical dimensions.

Single Zener Diodes Selection Notes

Select this component when a 47 V reference is required in a compact SMD form factor. The MicroMelf package supports automated assembly and offers a high operating temperature capability up to 175°C. Verify that the circuit design accommodates the 500 mW power dissipation limit and the specific dynamic impedance values provided in the datasheet for the intended load conditions.

Single Zener Diodes Part Context

This component belongs to the ZMC series of SMD Planar Zener Diodes produced by Diotec Semiconductor. The series spans voltages from 2.4 V to 75 V and utilizes the Quadro Glass Case construction. These devices are designed for commercial and industrial applications requiring standard reliability levels and are supplied in taped and reeled packaging for efficient surface-mount processing.

Single Zener Diodes Replacement Considerations

For automotive-grade applications where AEC-Q101 qualification is mandatory, the MM3Zxx-AQ series is the designated alternative. For other uses, verify pinout compatibility and ensure equivalent voltage and power ratings before substituting with components from different manufacturers.
