MM5Z4V7B

Single Zener Diodes Overview

The MM5Z4V7B is a surface-mount planar Zener diode manufactured by Diotec Semiconductor, housed in an SOD-523 package. It provides a nominal Zener voltage of 4.7 V with a tolerance range of 4.55 V to 4.75 V at a test current of 5 mA. The device features a sharp breakdown characteristic and low leakage current. Power dissipation is rated at 200 mW or 300 mW depending on copper pad area. Operating junction temperature ranges from -55°C to +150°C.

Single Zener Diodes Feature Summary

• Sharp Zener voltage breakdown for precise regulation
• Low reverse leakage current
• ±2% tolerance on Zener voltage
• RoHS compliant without exemption

Single Zener Diodes Applications

• Voltage stabilization circuits
• General-purpose voltage regulators
• Commercial and industrial grade electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -Q or -AQ) if automotive AEC-Q101 compliance is required, as standard versions lack this qualification. Confirm power dissipation requirements against your PCB copper pad layout, as ratings vary between 200 mW and 300 mW based on thermal conditions. Ensure the component meets RoHS standards without exemptions for your manufacturing process.

Single Zener Diodes Selection Notes

Select the MM5Z4V7B when a stable 4.7 V reference is needed in compact designs. Consider the ±2% tolerance for high-precision applications. Evaluate the thermal resistance values (620 K/W or 350 K/W) relative to your board's copper area to ensure safe operation within the 150°C junction limit. Verify that the dynamic impedance fits your circuit's noise requirements.

Single Zener Diodes Part Context

This component belongs to the MM5Z series of SMD Planar Zener Diodes from Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 47 V in the SOD-523 package. The MM5Z4V7B specifically targets applications requiring tight voltage tolerances and reliable performance in space-constrained commercial and industrial environments.

Single Zener Diodes Replacement Considerations

Check for exact voltage match and package compatibility. Verify if AEC-Q101 qualification is mandatory; if so, source parts with the -Q or -AQ suffix. Ensure thermal dissipation capabilities align with your design constraints.
